In connection pipes and pipe fittings which will be used to an accessory, these accessories to be called the stainless steel flange, of course, this is a little more professional, it is called, in life we may put them to look at as a joint part . In all material stainless steel flange which is best, but life is also long. First, note the use of the stainless steel flange A drain stainless steel flange parts and materials engineering are among the most commonly used, but in the process of using them to note is that under normal circumstances, the stainless steel flange can not be used alone to use, because the pipe The connection requires pairs of stainless steel flanges. stainless steel flange is used to connect two pipes of the same model. stainless steel flanged connections are also very unique, mouth end to be used in the two tubes connected together must be fitted with a stainless steel stainless steel flanges, and then connect the two tubes stainless steel flange stainless steel flange fitted sheet to that end is connected together. Second, the specific methods of stainless steel flange connection stainless steel flange is not directly connected to two pipes connected parts but a bridge, because the stainless steel flange need to be fitted into the mouth end of the two tubes, respectively, and then bonding the two pieces stainless steel flange again, if piped pressure gas or liquid is relatively small, you can also use a spiral pattern of the surface of the stainless steel flange, which is connected directly to tighten up even better. Third, the stainless steel flange affordability of gravity Compact and lightweight piece of stainless steel stainless steel flanges for pipeline gas or a liquid capacity of gravity, but very powerful. Even without the use of welding two stainless steel flanges can also withstand the pressure under normal circumstances, if the use of the welding of the way, then you’d be able to withstand over four kilograms of gravity. Want to make the connection stainless steel flange above play a more extreme effect, then select welding. stainless steel flanges connection are tips of the stainless steel flange itself is a way to connect two pipe fittings, and if you want the connections after having overall more airtight if you still need a little bit of technology and know-how. This time only two pieces of stainless steel mat in the floor mat stainless steel flange disc which is like, because this mat itself is a sealing material, it will make the gap between the stainless steel flanges have been filled.

Flange manufacture is a kind of forging industry, because the forging industry is environmental pollution, such as production will emit a lot of poisonous and harmful gas, will also release a lot of dust, in some advanced countries, requirements and regulations for the production is more, as a result, such as flange production forging industry mostly focused on developing a large number of production more. But in the international market, the demand for flange is larger, so the flange import export become one of the “industry in the world. In export flange which on the one hand, India has bigger superiority, because India’s human resources are very rich, processing the raw material of flange has very abundant, thus occupying the price is relatively cheap advantage, most of the flange on the international business from India. And this kind of situation, flange has brought great impact on China’s export. Wenzhou city of zhejiang province in our country are mainly processing flange and accounted for seventy-five percent of domestic exports of flange in the majority. At present is affected by the Indian market, wenzhou city export flange is evident in the downward trend. At present, the flange production situation appeared two outer situation, most rely on outsourcing is a raw material, the second is the product most depend on export. In view of the above situations, now mainly introduce the problems existing in the outlet flange of solving measures should be taken. Measures above one, said the flange production and export of raw materials want to rely on outsourcing situation at present, the production of products to export situation, the local government should timely adjust the enterprise’s management pattern, the structure of the assets of appropriate optimization, for example can take enterprise assets reorganization, or is the way to create a group, is the production of products in the international competitiveness. Then there is the firm’s ability to resist risks further strengthened. Measures on the development of flange forging industry, local government should take comprehensive consideration of the way, to make full of international and domestic market investigation, don’t appear in the production of blind phenomenon. Export quantity and quality of the flange must meet the requirements of the international market, make reasonable reserve flange processing equipment, is all sorts of unnecessary waste dropped to the lowest.

Who used for power station equipment decoration material, chemical, oil and other Settings. Stainless steel stamping elbow poor weldability, should be aware of before welding, heat treatment of speaking of choose suitable welding electrode. 7, electrode manipulation should link when dry, titanium calcium type should be 1 hour after 150 ℃ drying, low hydrogen type should be 1 hour after the 200-250 ℃ drying (cannot be repeated many times to dry, or coated convenient cracking flake), beware of covering viscous oil and dirt, so as not to cause weld added carbon content and affect the quality of weldment. 8, stainless steel stamping elbow, when welding the carbide precipitation by repeated heating, lower resistance to erosion and mechanical function.

Stainless steel flange is a kind of used to connect two pipes connection parts, in the entire plumbing system of stainless steel flange is just a part of the connection parts. Stainless steel flange are classified into the category of the stainless steel flange parts, flange can be connection and some of the water pump, there are some very small is similar to the valve connection device can also belongs to the stainless steel flange type, the following is about the production standards and rules for everyone to do the introduction. First, the stainless steel flange thickness have requirements Because of the different stainless steel flange have different purposes, so for the thickness of the flange itself also has the related requirements. Pipeline pressure brought by directly determines the thickness of the flange need to use. Different thickness can withstand the pressure of the pipeline is also has a very big difference. General situation, the pressure is the thickness of the stainless steel flange and pipe size has a proportional relationship, that is powerful pressure pipe need to use the thicker the thickness of stainless steel flange. Second, stainless steel flange connection mode determines the number of thread flange port stainless steel flange and pipe can use many kinds of methods, the combination of these methods directly determines the stainless steel flange port needs with many threads. If the pipe to pressure is not so big, so that it is using the screw turned the connection, this time only need to put the two pieces are bonded good stainless steel flange and two pipes respectively through positive and negative direction of the port of screw tight, this case the number of threads is more commonly. Third, stainless steel flange gaskets need to match each other in pairs Different types of flange should be carried out and the corresponding gasket to match, if pipe delivery pressure is bigger, the gasket also need to choose some heavy material. In the pipeline of the pressure particularly big, we choose the gasket material is metal, so that we can and stainless steel flange has a good auxiliary to each other. Of course according to the different levels of pressure for the classification of metal raw material of the gasket is also a choice, classification don’t deal with these materials should be in such an order, the first is the copper material, followed by aluminum, the last is the steel, made in different types of steel gasket can withstand the pressure is not the same. Stainless steel flange tie-in steel class gasket, the resistance of the role of the pressure pipeline space is one of the most obvious.

1, chromium stainless steel stamping elbow has must be corrosion resistant (oxidizing acid, organic acids, cavitation), heat-resisting and wear-resisting function. Who used for power station equipment decoration material, chemical, oil and other Settings. Chromium stainless steel stamping elbow poor weldability, should be detailed before welding, heat treatment of speaking of choose suitable welding electrode. 2, chromium nickel stainless steel stamping elbow has choiceness erosion resistance and oxidation resistance, widely used in chemical, fertilizer, oil, medicine, machinery manufacturing. 3, chrome and stainless steel stamping elbow sclerosing eve, after welding cracks easily occur. If the acceptance with typical chromium stainless steel stamping elbow electrode welding, required preheat above 300 ℃ and 700 ℃ after welding at the mercy of slow cooling treatment. If cannot undertake the weldment heat treatment after welding, should choose the chromium nickel stainless steel stamping elbow. 4, chromium nickel stainless steel stamping elbow, when welding the carbide precipitation by repeated heating, lower resistance to erosion and mechanical function. 5, chromium nickel stainless steel stamping elbow coated with titanium calcium type and low hydrogen type. Titanium calcium type can be used for ac/dc, but when the ac welding penetration, redness easily at the same time, therefore, stainless steel stamping elbow as general acceptance of dc power supply. 6, stainless steel stamping elbow manipulation should link when dry, titanium calcium type should be 1 hour after 150 ℃ drying, low hydrogen type should be 1 hour after the 200-250 ℃ drying (cannot be repeated many times to dry, otherwise the medicine skin peeling easy craze), beware of the stainless steel stamping elbow coated viscous oil and dirt, lest cause stainless steel stamping elbow add carbon content and influence welding quality of weld. 7, chrome and stainless steel stamping elbow, appropriate for the improved corrosion resistant function and weldability add adequate stability element Ti, Nb and Mo, weldability is chrome and stainless steel stamping elbow is better. Acceptance with typical chromium stainless steel stamping elbow, should be above 200 ℃ preheat and at the mercy of 800 ℃ and tempering treatment after welding. If weldment not for heat treatment, should choose the chromium nickel stainless steel stamping elbow.

Stainless steel flange is used widely in modern industrial one of a kind of material, admired for many years, also let many businesses see business opportunities, have come into the production of stainless steel flange industry. There are a lot of friends don’t really know the stainless steel flange, just feel familiar for this name. If don’t participate in industry, many industries will not be able to normal operation, our life will be hit by the very serious also. Stainless steel flange is not mysterious, just to tell you that what is called stainless steel flange. First, the classification of many Is the so-called birds of a feather flock together a person with group of points, there are certain classification, so is a stainless steel flange. For the simplest case, just as we often see the film. Movie just a broad categories, also can be pided into: thin horror film, literature and art films, comedy, martial arts films… Many branches. In stainless steel, stainless steel flange, flange, can be pided into five categories, that is the most basic of five types of stainless steel flanges, pided into: butt welding flange, screw, flat welding, socket welding… Such as flange. Different types of stainless steel flange, on the design structure is different, can play a different role. Second, design more integrity Stainless steel flange on design has more integrity, resistance to corrosion of the stainless steel itself is very strong, because of strong corrosion resistance, in order to guarantee the use of stainless steel flange normal, not rusting, beyond the general of the flange. Because of the high strength of corrosion resistant ability, structure parts can remain in the best state, the same as the original design of the complete, effectively play a biggest role. Stainless steel flange is different, but all giant won’t produce the phenomenon of corrosion or wear and tear, is the use of industrial production and use. In the design of the stainless steel flange is strong, is also a kind of the most durable of the flange, is also the most environmentally friendly material, and our life is closely linked. Can be used in pipeline engineering, can also be used in aerospace engineering, the real power. Widely used for stainless steel flange is more and more is not mysterious, gradually opened the mysterious veil themselves, let us closer to the contribution to we did a lot of stainless steel flange.

Speaking of stainless steel flange, estimates there are a lot of friends for this name is very strange, stainless steel flange is very versatile. But there are a lot of friends do not know what is its true purpose. Here, let us come into the real world of stainless steel flange, personally solve stainless steel flange of the veil for you. In the industry, we are a lot of lack of the application of stainless steel flange, such as in the construction industry. First, high temperature resistant Before the flange, can very good used in the construction industry, construction industry, the use of stainless steel flange is very broad, we can at any time on site to see the shadow of the stainless steel flange. Stainless steel flange that is fully illustrated the immortal status in the architecture, is a lot of things can go beyond. Largest stainless steel flange is a bit of high temperature tolerance, can is good enough to withstand high temperatures, therefore, stainless steel flange in industry are invincible good situation. Second, widely participate in hot water system Stainless steel flange the tolerance of heat is just has been said, is very high. Therefore, the most popular in the construction industry. Stainless steel flange to the most high quality drinking water system is very appropriate, and hot water system, stainless steel flange are widely used in the hot water system, good tolerance is used as the main reason for the hot water system. Can be the best one of a pipe, water supply system is very competitive in the market. Third, health, environmental protection In today’s society, always faces many pollution status, we emphasize on environmental protection all day, but the real to do environmental protection, we should start from the side of the small. So let the stainless steel flange on the industry market has huge competitiveness. It is also because the stainless steel flange environmentally safe, need not use there will be pollution phenomenon. The advantage of stainless steel flange, in the construction industry has a competitive enough, the heat is very good, and handling of the drinking water system perfect, its environmental security features, become the leader in the industry. The most important part of the stainless steel flange is the environmental protection, can provide human with more convenient, let our life, pollution free, live in an environment of low carbon environmental protection. Therefore, the stainless steel flange is widely application in the construction industry.

Stainless steel flanges pivotal position in the industry, its production and processing methods also have some differences, it is precisely because of the influence of the stainless steel flange itself determines the increase in manufacturers. Production of stainless steel flanges increased, but also further promote the production process, but the production process is not all manufacturers of stainless steel flanges are good, there are some gaps. In the processing of stainless steel flanges, there are some considerations, Below, to tell you some of the most simple precautions it. First, anti-corrosion treatment is not enough Not just stainless steel flanges, stainless steel products for other terms as well. As stainless steel flange, the most afraid of is the aspect of corrosion corrosion treated properly enough. On, for example, our water systems now. After the water supply system, to use a stainless steel flanges, stainless steel itself against corrosion and rust if the treatment process is not good, then use soon, it will advance the rust, people drinking rusty water, of course, sick , rust often contain many bacteria produce. Second, the surface treatment is not good, there are scratches, etc. Stainless steel products, for scratches the surface, are taboo, if the product has a scratch time, will certainly find a way to get rid off. Thus, in the scratch is likely hiding places such as bacteria, there will be the presence of impurities and other things. Long maintained, it would produce rust. Gradually expand significantly. So, once the stainless steel flanges scratches in the production and processing time, it will certainly be even dispose of, in order to avoid an even greater crisis, the quality of the product also makes highly questionable. Scratches caused by human activity is the most serious, even if the surface treatment is good, also in the late scratches, therefore, to pay more attention at the time of production, do not appear flawed. Only know the process of production of stainless steel flanges considerations of these only after manufacturing a better, more craftsmanship stainless steel flanges. In industrial production, the quality of stainless steel flanges are also extremely important, with our healthy living has great relevance, and therefore in terms of the production process of certain stainless steel flanges better, these considerations are, are to be avoided, to avoid the minefields, the improvement in the production process as soon as possible the above deficiencies.

When buying stainless steel flanges, a lot of my friends do not know how should buy. It could easily deceived. Stainless steel flange on the market is extremely strong, so many unscrupulous traders, in order to reap huge profits, what do unethical things out. This is more a test that we are not having a pair of “eyes” see through all of the scam, very good to protect their legitimate rights and avoid fooled. How reasonable choice stainless steel flanges: First, look at the price of stainless steel flanges Different flange has a different price, however, prices are not exorbitant stainless steel flange, saying the production process, brand and so has great relevance. The price is different. With a specification of the stainless steel flange prices are comparable. But if you find yourself buying stainless steel flange below the market a lot of words, do not buy, to avoid buying inferior products. Second, look at the stainless steel flanges classification Stainless steel flange is just a category, there are many small classification. Not every type of stainless steel flange price are the same, so that different types of stainless steel flange also have some differences in terms of price. So, we choose stainless steel flanges, when will certainly need to figure out their own classification. Different types of stainless steel flange price is different, in particular use also different. Third, look at stainless steel flanges brand It seems that every industry has so few relatively high profile brands. High-profile brand in terms of quality, quality, production technology, as well as other aspects of after-sales is guaranteed. Meanwhile, the stainless steel flange also has many brands, different manufacturers of stainless steel flanges in quality with quality aspects are different, performance, corrosion protection is not the same. When we buy stainless steel flanges can choose more well-known brand, so the quality is relatively very assured. Choose stainless steel flange is a technology live, but also a test of eyesight of living. A little lax, it is possible to buy substandard flange, buy quality, but off the flange. Directly affects the effects used to bring a lot of inconvenience to use, all that we choose stainless steel flange time, should pay more attention, do not blindly choose, look at the price, look at the material, look at the brand , indispensable.

Flange on some professional connection is one of the very common parts, whether it’s part of the equipment connections, or the whole pipeline connection, they all need to use this part to the flange. Water pump connection is a part of the connection, this time will need to use the stainless steel flange parts. Flange can be used in many types of connection, a little small connection valves, large connection like pipeline engineering. First, the flange gasket material The vast majority of the flange gasket is never is a chunk of metal material cutting down above, the production and the flange gasket is also need by those very professional manufacturers. Production need according to certain size because the gasket is combined with flange, so size to match the flange. Stainless steel flange gasket materials species persity, asbestos, rubber sheet, asbestos board has, and polyethylene this synthetic material. In addition to non-metallic materials and some metal materials gaskets, where metal materials are very thin metal plate (material, such as galvanized sheet and stainless steel. Second, combined flange gasket Want more good sealing performance, you will need to make their own installed for use. Of metal gasket is made and some nonmetallic material similar to that of asbestos, of this package them together is the metal package gaskets. In addition to the gasket and a spiral wound gasket. When the gasket stainless steel flange connection is also very common. This is the use of thin steel tape material and asbestos tape wrapped together is made and be become. Third, flange gasket suitable occasion Different flange gasket can be used in different environments, some common rubber gasket can be used in the environment of temperature is not particularly high, generally need to temperatures below one hundred and twenty degrees Celsius. In stainless steel flange connection of asbestos rubber gaskets are also common, their use in need of water vapor temperature below four hundred and fifty degrees Celsius. When flange connection oil temperatures below three hundred and fifty degrees, the pressure will be less than five million mpa. Those who have the corrosion performance of pipe connection in addition to the need to use to stainless steel flange, corrosion resistance of the gasket is required. Asbestos plate gasket is a very good choice, because it can resist acid erosion of the flange.

Austenitic stainless steel with solid solution treatment to soften, the steel wire are heated to a temperature of about 950 ~ 1150 ℃, heat preservation for a period of time, make the carbide and various alloy elements fully dissolved in austenite, evenly and rapid quenching water cooling, carbon and other alloying elements can not afford time to precipitate, obtain pure austenitic organization, called the solid solution treatment. The effect of solid solution treatment with three points. 1, make steel wire organization, and composition is uniform, it is especially important for raw materials, because of the hot rolled wire rod paragraphs is not the same as the rolling temperature and cooling speed, caused the organizational structure. Atomic activity increased at high temperatures, the sigma phase solubility, tend to be more uniform chemical composition, rapid cooling after get uniform single-phase organization. 2, remove the work hardening, can continue to cold. Through the solid solution treatment, skew lattice, elongation and breakage of recrystallized grains, eliminate internal stress, the steel wire tensile strength decreased, elongation increased. 3, restore the inherent corrosion resistance stainless steel. Carbide precipitation due to cold working, lattice defects, make stainless steel corrosion resistant performance degradation. Steel corrosion resistance after solid solution treatment back to his best. For stainless steel flange, the three elements of solid solution treatment temperature, holding time and cooling rate. Solid solution temperature is mainly determined according to chemical composition. Generally speaking, variety and high content of alloy elements brand, to increase solid solution temperature. Especially manganese, molybdenum, nickel, high content of silicon steel, only to improve the solid solution temperature, make it dissolves, to achieve a softening effect. But stabilized steel, such as 1 cr18ni9ti, solid solution at high temperature stabilization element of carbide dissolves in austenite, in the subsequent cooling in the grain boundary precipitates in Cr23C6 form, caused by intergranular corrosion. For the stabilizing element of carbide (TiC and NbC) decomposition, solid solution, generally USES the lower solid solution temperature.

The stainless steel products is arguably life is everywhere, and because of that, we have a lot of stainless steel. For example, is not easy to rust on the stainless steel products, stainless steel products more durable, and so on. And speaking of stainless steel flange, there are lots of people will feel this kind of things are new, after all this stuff we ordinary people in life are not commonly used. As a matter of fact, stainless steel flange have greater use in the production and life. The following is the stainless steel flange manufacturer to introduce the stainless steel flange of the related knowledge. Although stainless steel product in our production has already been widely used in life, but in stainless steel flange of the standardization of this kind of product manufacturing in China started relatively late but. Facing the current situation of the stainless steel flange is in our country, not only relatively small variety of specifications, and the production scale is small, not the circulation is not smooth, and grade of the product is very few. There also exists the cause of the enterprises with the production of stainless steel flange site too much and too scattered, this way of concentration of appeared in the social production, because it is very not easy to manage, and the result is the product quality is not up to standard. The following stainless steel flange manufacturer is based on the status quo of the above introduction of stainless steel butt welding flange used to pay attention to matters, First, the use of welding technology, through the current is not too big, under normal circumstances is 20% less than in welding, then there is operation arc not too long, as for the interlayer cold fast, can use narrow welding technology. As long as to avoid the above several kinds of circumstances, stainless steel butt welding flange will avoid corrosion phenomena. Second, the use of electrode must keep dry, if necessary, can adopt the method of drying prompted the use of the electrode in the dry state. But here, stainless steel flange manufacturer to remind is, can’t repeatedly adopt the method of drying is good to avoid the need to keep dry peeling. Third, stainless steel flange manufacturers want to emphasize is the chromium stainless steel used for welding methods, there will be a larger sclerosing American standard, and thus prone to crack. If the same type of welding electrode, the prophase work need to do is to preheat the cold treatment, to ensure the normal use of after welding of the flange.
