Pipe tee is a pipe for pipeline branch. For using seamless tube manufacturing pipe tee is usually adopted by the process has two kinds of hydraulic bulging forming and hot pressing. A hydraulic bulging: three links of hydraulic bulging is through the metal materials of axial compensation bulge out a kind of branch pipe forming process. The process is to use special hydraulic press, with three links within the tube billet diameter equal injection liquid, through the two horizontal side of the hydraulic cylinder synchronization of the motion of tube billet, billet after squeezed smaller volume, smaller volume of liquid with the tube billet inside the tube billet and pressure, when pressure pipe tee branch pipe bulge out to the metal material in the liquid in the cylinder and the pipe pressure under the dual role of flow along the mold cavity and the branch pipe. 2. Thermoforming: pipe tee thermoforming is greater than three links of the diameter of the tube billet, flattening diameter size, about to pipe tee at the site of the tensile branch open a hole; Tube billet heating, in the forming die, and within the tube billet load stretching pipe punching die; Under the action of pressure pipe by radial compression, the radial compression in the process of metal flow in the direction of branch pipe and branch pipe formed under tensile of progressive die. The whole process of the pipe is made by the radial compression and branch pipe drawing process and forming parts. Unlike hydraulic bulge forming pipe tee, hot-pressing pipe tee branch pipe of metal is of the pipe by the radial motion compensation, so also known as the radial compensation technology.

Sanitary pipe fittings are used for a relatively high level of health fittings, the main material for the composition of stainless steel. Although it is stainless steel, stainless steel is also a time when the rust. Since it is sanitary pipe fittings, if it is rusty, then it can not be used as a health, so in the use of time must be to prevent the health of the pipe rust, the following describes several effective way to prevent sanitary pipe rust. 1, not in contact with other metals Sanitary pipe fittings will be exposed to dissimilar metals and rust, such as fixed screws. At the beginning may not be very serious, you can use the sea or cloth, plus a neutral cleaning agent to wipe, it is also easy to clear rust. After cleaning must be careful not to let the cleaning liquid to stay in the above. If the beginning did not pay attention to the late will show a serious brown rusty state. If this is the case, you can use some stainless steel cleaning solution or 15% concentration of nitric acid dilution after cleaning work. Of course, there may be a very stubborn rust, so you can use a stainless steel brush to wipe the wipe, and finally clean with a cleaning solution. 2, Sanitary pipe fittings affected by the gas caused by rust In some factories or in the streets of a large number of traffic environment, the surface of stainless steel is very easy to pollute, and sometimes will show a small spot rust. Most of these conditions are affected by cars, cold and warm gas excluded by the rust. When the pollution is mild, you can use a neutral detergent or soapy water can be cleaned, but the serious time can not be simply handled. If you use this environment for a long time, then it is necessary to regularly clean the Sanitary pipe fittings. 3, the impact of the environment Such as in the coastal area and other positive sea breeze blowing, stainless steel also hi in the short term produce red rust. But also faster than rust in other areas. If you can not avoid these problems, you can only slightly stronger corrosion resistance of 316 stainless steel, but also regularly do a good job cleaning. 4. Sanitary grade pipe attached to the cleaning solution caused by rust If the neutral detergent can not be used to clean, the use of cleaning liquid to clear. 5. Sanitary grade pipe due to hand or fingerprint caused by rust If the neutral detergent can not be used to clean, then use sponge, cloth, and so on with organic solvents (alcohol, light oil, acetone, etc.) to wipe. This method can not be completely removed, and then use stainless steel cleaning liquid to clear. In general, a variety of cleaning methods to do after cleaning, you must do a water rinse.

After processing and molding, the surface of stainless steel pipe fitting should pass a certain treatment to make more excellent performance of the stainless steel pipe fittings, say if the stainless steel pipe fittings that is not processed then its superiority is shown not to come out. So what treatment will you take to the surface of the stainless steel pipe fittings? Usually the most common surface treatment methods have several: surface color bleaching processing, surface mirror guang liang treatment, surface coloring treatment. Surface color bleaching processing: stainless steel in the process of machining, through rolled plate, edge, welding or through artificial surface fire heating processing, producing black oxide coating. The hardness of film of oxide skin mainly NiCr2O4 and NiF two EO4 composition, before the general removal using strong corrosion of hydrofluoric acid and nitric acid method. But this method cost, environmental pollution, harmful to human body, corrosion resistance, be being washed out gradually. At present to scale processing method mainly has two kinds: Sand blasting method (pill) : mainly adopt the method of spray micro glass bead, remove black oxide on the surface of the skin. Chemical method: using a non-polluting pickling passivation paste and normal temperature non-toxic cleaning fluid with inorganic additives for baptism. To achieve the aim of bleaching processing stainless steel color. Handle is largely seems to be a light color. This method is useful for large, complex products is. Mirror bright stainless steel surface treatment: according to the complexity of the stainless steel products and the user request is different respectively by mechanical polishing, chemical polishing and electrochemistry polishing method to achieve bright luster. Surface coloring treatment: stainless steel coloring stainless steel products of various colors, not only increase the designs and varieties of products, and improve the wear resistance and corrosion resistance. Stainless steel coloring method has the following kinds: 1, chemical oxidation coloring 2, electrochemical oxidation coloring 3, ion deposition oxide coloring 4, high temperature oxidation coloring 5, gas phase cracking staining method Source: China pipe fitting Manufacturer – wilsonpipeline Pipe Industry Co., Limited (www.wilsonpipeline.com)

In the purchase of stainless steel pipe fittings and other stainless steel products, usually the price of stainless steel products are measured by its weight, and sometimes we have to know its weight is not accurate, so we must through a certain method to estimate the stainless steel pipe fittings weight. Here are some of the estimated method of stainless steel weight. ● Chrome stainless steel to take 7.75 tons / M3 ● chrome-nickel stainless steel to take 7.93 tons / M3 ● iron to take 7.87 tons / M3 Standard Calculation Formula of Stainless Steel Plate Steel Product Weight Weight (kg) = Thickness (mm) × Width (mm) × Length (mm) × Density Density material 7.93 201,202,301,302,304,304L, 305,321 7.75 405, 410, 420 7.98 309S, 310S, 316S, 316L, 347 Stainless steel rods, wire, theoretical calculation formula ★ diameter × diameter × 0.00609 = kg / m (for 410 420 420j2 430 431) For example: ¢ 50 50 × 50 × 0.00609 = 15.23Kg / m ★ Diameter × diameter × 0.00623 = kg / m (for 301 303 304 316 316L 321) For example: ¢ 50 50 × 50 × 0.00623 = 15.575Kg / m Stainless steel profiles, theoretical formulas ◆ hexagonal bar on the side × opposite side × 0.0069 = Kg / m ◆ square bar wide width × width × 0.00793 = Kg / m Stainless steel pipe, theoretical calculation formula ○ (outer diameter – wall thickness) × wall thickness × 0.02491 = Kg / m For example, ¢ 57 × 3.5 (57-3.5) × 3.5 × 0.02491 = 4.66Kg / m Standard calculation formula for stainless steel pipe Pipe (outer diameter – wall thickness) X wall thickness X0.02491 = weight per meter Round steel outside diameter X outside diameter X0.00623 = weight per meter Pipe pressure = wall thickness ※ OD X416 = MPa X9.8 = kg with 30% Square tube of the formula is: 0.0246615 * (side length * 4 ÷ 3.14 – thickness) * thickness.

Stainless steel elbow is the use of stainless steel processing made of elbow, the advantages of stainless steel we all know that it is more resistant to corrosion, so the stainless steel elbow after the completion of the use and storage of which is also to pay attention to some of the problems, although stainless steel Material is more resistant to corrosion, but if the maintenance of improper storage, then it is easy to cause damage and pollution of stainless steel elbow. In the use and maintenance of stainless steel elbow need to pay attention to a lot of things, users need to follow a certain method of use, in accordance with accurate and fair method of use and maintenance. Note the following: 1, long-term storage of stainless steel elbow, should be checked regularly, often on the exposed surface to be clean, remove the dirt, cleanly stored in the indoor dry place, is strictly prohibited or open storage. Often keep the stainless steel elbows dry and breathe, keep the fixtures clean and clean, and store them in accordance with the exact storage method. 2, the installation, the stainless steel elbow can be connected directly by the way in the pipeline, according to the location of the installation. Under normal circumstances, can be installed in any position on the pipeline, but need to facilitate the operation of the inspection, pay attention to cut off the stainless steel elbow media flow should be below the vertical valve flap, stainless steel elbow can only be installed horizontally. Stainless steel elbow in the installation should pay attention to sealing, to prevent the phenomenon of thrown, affecting the normal operation of the pipeline. 3, stainless steel elbow ball valve, globe valve, gate valve use, only for full open or closed, do not agree to do with the regulation of flow, so as to avoid the erosion of the sealing surface to accelerate wear. Gate valve and the upper thread cut-off valve with inverted sealing device, hand wheel to the top position of the tightening, you can prevent the media from the filler leakage. 4, stainless steel elbow application hand wheel, do not use the lever or other tools, so as not to damage the valve. Handwheel turns clockwise for rotation, and vice versa. When you use justice, to ensure accurate use of methods and means. 5, stainless steel elbow valve packing gland bolts should be tightened evenly, should not be pressed into a crooked state, so as not to bump the stem movement or cause leakage. 6, stainless steel elbow in the use of the process, should always keep clean, the transmission thread must be lubricated on time, found fault, should immediately stop using, to identify the reasons to clear the fault.

Stainless steel pipe fittings are usually installed when the need for welding, due to the special nature of the material, stainless steel pipe fittings in the welding is different from the ordinary pipe welding. And welding finished the treatment of the weld is different, stainless steel pipe weld not only requires the beauty can not rust, then the stainless steel pipe welding and processing process is how it? As the stainless steel pipe pieces of different sizes, according to the unique place of stainless steel pipe welding, as far as possible to reduce the amount of heat input, so the use of manual arc welding, argon arc welding two methods, d> Φ159 mm using argon arc welding, Arc welding cover. D ≦ Φ159 mm full of argon arc welding, stainless steel pipe welding technical requirements are as follows: ①manual arc welding machine using DC reverse, argon arc welding with DC is followed. ②welding should be welded with stainless steel wire brush off the surface of the oxide, and acetone washing, the electrode should be 200-250 ℃ drying 1h, with the take with the use. ③Clean the oil in the range of 25 mm on both sides of the workpiece groove before welding, and wash the groove on both sides with 25 mm on both sides of the bevel. ④argon arc welding, the nozzle diameter Φ2 mm, tungsten is extremely pot tungsten, specifications Φ2.5 mm. ⑤TIG welding stainless steel, the back must be filled with argon protection, in order to ensure the back forming. Using the method of partial argon in the pipeline, the flow rate of 5-14L / min, positive argon flow rate of 12-13L / min. When welding the thickness of the weld should be as thin as possible, and the root fusion outstanding, when the arc into a slow slope, if the arc shrinkage, the application of grinding machine wear off. Must be arc in the groove arc, arc should be filled with craters, to prevent cracks in the arc. As the stainless steel pipe fittings for the austenitic stainless steel pipe, in order to prevent carbide precipitation and intergranular corrosion, should strictly control the inter-layer temperature and post-weld cooling rate, the requirements of the inter-layer temperature control between 60 ℃, Immediately water-cooled, while the use of sub-welding. This symmetrical dispersion of the welding sequence, you can increase the joint cooling rate, but also reduce the welding stress.

The use of stainless steel pipe fitting is very wide, not only because of its high corrosion resistance, stainless steel tube bright and beautiful appearance also played a certain decorative role. Usually the surface of the stainless steel pipe is bright, we feel that the better the stainless steel pipe, in addition to the late grinding treatment, what factors can affect the brightness of stainless steel pipe it? Production of stainless steel pipe fittings after annealing the brightness of the product determines the quality of the product. Affect its brightness there are many, here for everyone to talk about the most important five factors: 1, the annealing temperature is to achieve the required temperature Stainless steel pipe heat treatment is generally taken to solve the heat treatment, which is commonly known as “annealing”, the temperature range of 1040 ~ 1120 degrees (Japanese standard). You can also observe the hole through the annealing furnace observation, the annealing area of the stainless steel pipe fittings should be incandescent state, but did not appear softening spreader sagging. 2, the annealing atmosphere is generally used as the annealing atmosphere of pure hydrogen, the atmosphere purity is best to more than 99.99%, if the atmosphere is another part of the inert gas, then the purity can be lower, but definitely can not contain too much oxygen, water vapor. 3, the furnace sealed bright annealing furnace should be closed, and the outside air isolation; the use of hydrogen as a protective gas, and only one exhaust port is through (to ignite the discharge of hydrogen). Check the method can be used soap water wiping the joints in the annealing furnace joints to see whether the run; which is the most easy to run the place where the furnace into the pipe and the place where the tube, the place of the ring is particularly vulnerable to wear, Always check for regular changes. 4, to protect the gas pressure In order to prevent the occurrence of micro-leakage, the furnace gas should maintain a certain positive pressure, if it is hydrogen protection gas, the general requirements of more than 20kBar. 5, the furnace steam on the one hand to check the furnace material is dry, the first furnace, the furnace material must be dried; the second is into the furnace stainless steel pipe is too much residual water stains, special pipe above if there are holes, Do not leak into the gas, or else put the furnace atmosphere destroyed. Generally, if normal, then the furnace should be back after about 20 meters of stainless steel pipe will begin to shine, bright reflective of the kind of need to pay attention to the most important thing is that we mentioned in the above knowledge, and hope that everyone in the production When you can pay attention.

In a piping system, the elbow is a pipe fitting that changes the direction of the pipe. According to the angle, there are 45 ° and 90 ° 180 ° three kinds of the most commonly used, according to the project also includes 60 ° and other non-normal angle elbow. Elbow materials are cast iron, stainless steel, alloy steel, malleable cast iron, carbon steel, nonferrous metals and plastics. Elbow weight calculation formula: Circle volume = 2X3.14X3.14 (r ^ 2) R R – Circle radius R – Ring radius of rotation Hollow tube ring volume = 2X3.14X3.14 ((r ^ 2) – (r ‘^ 2)) R R ‘- radius of the inner circle of the ring 90,60,45 degrees elbow (elbow) volume is the corresponding hollow tube ring volume of 1/4, 1/6, 1/8. The density of steel is calculated on the basis of weight by 7.85 kg / m dm, density X volume = weight (mass). Note: 1,180 ° elbow calculated by the table 2 times, 45 ° by 1/2; 2, R1.0DN elbow weight calculated according to Table 2/3; 3, the table does not list the weight of the wall thickness, preferably with the similar two weight calculation of the average; 4,90 ° elbow calculation formula; 0.0387 * S (D-S) R / 1000 where S = wall thickness mm D = diameter mm R = bending radius mm Source: China Elbow Manufacturer – wilsonpipeline Pipe Industry Co., Limited (www.wilsonpipeline.com)

Flange manufacturing process, including forging and casting two processes, the two of them in the end what is the difference? Different in craftsmanship Forging flange process: forging is the metal heated to soften the state, through the external force hit, the formation of the required shape. Casting Farah process is: casting is the metal melt after the liquid into the mold in advance to make it cooling forming, casting process industry called Fansha. Product quality is different Forging flange than the cast flange its strength is relatively high, the quality is better, the general low-quality pipe will be used to connect the casting flange, high-quality pipeline forging flange for the connection. Use the different range Forged flange quality is better, the use of high-quality pipeline, can play a sufficient performance, is used in low-quality pipeline is of no use. Casting flange can only be used in 16Kg, normally used in 10Kg or 6Kg of the pipeline. Temperature requirements In addition to pressure requirements, the temperature can not be too high or too low. There is no general specification, but the important pipeline is recommended to use forging flange, such as some high temperature difference or pipe vibration place, casting flange quality may cause broken, crack, leakage and so on. Casting blanks due to the advantages of small margin in some unimportant occasions can also be used. Forged flanges do not have these defects, high-quality pipe installation is very common.
