To improve the performance of the sheet metal, usually by heat treatment process, through the different annealing, tempering and quenching, change the plate inside the atomic distribution, in the forging and stamping process, cold processing, thereby improving the performance of the sheet metal. The flange is usually the most widely used to start from here, to improve the metal performance of flange by different processing. First of all, to understand the performance of flange. The flange workpiece exposed to air, oxidation often occurs in stainless steel flange. Decarburization (i.e. the carbon content of steel parts surface, the lower) after heat treatment of parts surface properties have very adverse effects. The flange metal should normally be controlled atmosphere or protective atmosphere. Melting salt and vacuum heating, can also be used to paint or packaging methods to protect the heating. And then through the heat treatment process, generally including heating, heat preservation, cooling three processes, heating and cooling of the two processes. The general annealing cooling speed, normalizing cooling speed, quenching speed. But also because different types of steel have different requirements, such as empty steel can be used as the cooling rate of normalizing quenching. Flange these processes are connected with each other, can not be interrupted. Finally, the importance of the heat treatment process of the flange is emphasized. The selection and control of heating temperature are the main problems to ensure the quality of heat treatment. The heating temperature is processing of metal materials and heat treatment purposes vary, but generally are heated to above the phase transition temperature for high temperature structure. Special steel flange heating is one of the important processes of the heat treatment. A lot of the flange metal heat treatment method, the first is the use of charcoal and coal as a heat source, then application of liquid and gas fuel. In addition, the flange can be applied at high temperature and high pressure, high corrosion and other harsh environment. Change the performance of metal heat treatment on the flange so clearly every time, find out the most suitable flange.

Threaded flange‘s English name: threaded flange that is connected to the equipment or pipe thread flange. 1. Chromium stainless steel flange pipe sclerosing beautiful mark after welding flange is bigger, is easy to crack. If using the same type of chromium stainless steel electrode (G202, G207) welding, must be above 300 ℃ preheat and 700 ℃ or so slow cooling after welding. If stainless steel flange welding cannot be heat treatment after welding, should choose stainless steel flange pipe fittings electrode (A107, A207). 2. Stainless steel threaded flange, in order to improve the corrosion resistance and weldability and increasing stability element Ti, Nb, Mo and so on, some good weldability is chromium stainless steel flange. Using the same type of chromium stainless steel flange welding electrode (G302, G307), should be above 200 ℃ preheat and around 800 ℃ tempering treatment after welding. If cannot undertake the weldment heat treatment, should choose stainless steel flange pipe fittings electrode (A107, A207). 3. The threaded flange pipe fittings, stainless steel flange welding rod has good corrosion resistance and oxidation resistance, widely used in chemical, chemical fertilizer, oil, medicine, machinery manufacturing.

For stainless steel flange plane milling, the milling efficiency and service time are the decisive factors in the economic impact of a compromise. Have a kind of mixing equipment company, to test the process of machining, can find a significant improve the rigidity and toughness of high quality stainless steel milling efficiency. Forging ring with the material of 1.4462 the usage of package materials by shoveled a square cutter mixed funnel. And at right angles to a side of face milling cutter transition section milling Mixing and the field of mineral processing technology, is located in, burns wilsonpipeline is the world’s largest a supplier of stainless steel flange. Cutting composition must be economic and technical improvement of the exploration, the company with particular emphasis on chemical and high temperature resistant stainless steel flange bags. In the operation, must be in a very short period of time to achieve a lot of cutting ability, but at the same time to achieve a longer tool life. Therefore, in the past the use of high speed steel cutter and cutter, duplex stainless steel flange to live longer, more reliable performance tools to replace. The first stage of the experiment Ingersoll milling machine, choose to use common steel 1.4462 bags, such as 10 meters in the ladle and a diameter of 250 mm need shaft centrifuge. A total of 10 steel bag shape can be mixed according to the corresponding mixture and shovel. Two special shape steel rings on both sides of the bag seal on the backbone. In both the steel pocket, a milling to mix a bucket specifications square support. So far has been the use of a diameter of 50 mm nested end mill, but in the cutting efficiency and surface quality and the service life of the results is not too big. Choose five adjust the blade Angle of 90 degrees, at right angles to a diameter of 50 mm 2 j1c eng stainless steel flange surface knife, to achieve 84.24 m3 / min cutting ability, more than 6% higher than competitors. These achievements mainly due to 53 m/min cutting speed, feed 0.1 mm/teeth, 10 mm, 50 mm cutting depth of the successful application of cutting width. Feed through three, twist the ladle receive wet milling. Copying milling cutter blade with excellent heat resistance. Compared with competitors orthogonal face milling cutter, long service life, in the same cutting condition similar by Ingersoll rectangular plane milling machine processing of three parts, the main processing time 50%, therefore, the ability of additional equipment in six hours. wilsonpipeline case processing, the company’s future plans, the most important thing is nested in wet milling cutter with high temperature tolerance. Through good Angle and the sharp cutting blades, in the processing of stainless steel, can realize the feed quantity of 10 mm. As a first step after two nested 5 w7k type by a knife was tested. First, using tool steel 66 mm in diameter. The first knife knife to take the standard trajectory, so the following data and synchronize milling appearance: cutting speed 120 m/min, cutting depth is 2 millimeter, cutting width 50 mm, promote the quantity of each tooth of 0.5 mm. In the first test, and the ladle 15 wet feed, then ten times dry milling. In the longer run during this time there will be a knife after tumor free surface and minor wear and tear, so in the future all ladle wet processing. And the use of a diameter of 80 mm, there are six effective by a cutter blade. In the same numerical cutting, the cutting machine at the top of the flat bag 16.7 min dry milling, cutting machine with the CD’s rivals, which greatly improve the life of cutter.

A pipe end is the description of how the section of pipe ends.  There are three main types of pipe ends: beveled, threaded or plain.  Understanding pipe ends is important when designing a piping system since it would be inappropriate for the designer to specify a threaded connection for a large diameter pipe or to specify a welded end when connecting to a threaded component. BEVEL END A bevel is a surface that is not at a right angle (perpendicular) to another surface. The standard angle on a pipe bevel is 37.5° but other non standard angles can be produced. Beveling of pipe or tubing is to prepare the ends for welding. However, it can also be used for deburring the cut ends for safety or aesthetic reasons. Bevel End is abbreviated on drawings as BE. The beveling process is generally automated. This is because a pipe beveling machine can cut the bevel much faster than hand grinding, flame cutting or turning the pipe on a lathe. Further, the automated process ensures that there is an accurate and consistant pipe bevel each time. The automated process is much safer as operating personnel are not exposed to the same hazards as a person beveling the pipe. This is the most commonly used end and is used on pipe, pipe nipples, and swage nipples. THREADED END Typically used on pipe 3″ and smaller, threaded connections are referred to as screwed pipe. With tapered grooves cut into the ends of a run of pipe, screwed pipe and screwed fittings can easily be assembled without welding or other permanent means of attachment. In the United States, the standard pipe thread is National Pipe Thread (NPT). The reason for this is that as NPT connections are assembled, they become increasingly more difficult for the process to leak. The standard taper for NPT pipe is 3/4″ for every foot. Threaded End is abbreviated on drawings as TE. Threaded fittings have threads that are either male or female. Male threads are cut into the outside of a pipe or fitting, while female threads are cut into the inside of the fitting. As screwed pipe and fittings are assembled, two pieces are pulled together. The distance that is pulled together is called the thread engagement. PLAIN END A pain end pipe is a pipe that has been cut at 90° perpendicular to the pipe run. The reason pipe would be specified as plain end rather than beveled end is when the pipe will be used in a socket weld connection or for use with a Slip-on Flange. ABBREVIATIONS Common abbreviations for the types of pipe ends are as follows.  In general, these are used to describe pipe nipples on drawings.

Everyone know large (large diameter) stainless steel flange processing and transportation are the need for welding process, but because of the toughness of the stainless steel flange is poorer, if direct welding process, welding deformation is bound to, affect the overall performance of the flange. So according to the welding deformation of the stainless steel flange, here share with you how to ensure the flange after welding of stainless steel product performance. Usually refers to stainless steel flange welding deformation, including two aspects: one is the processing before the welding deformation of blank is processed for stainless steel flange and vessel compound welding when the welding deformation. Deformation of the former besides literature described two kinds of deformation, there are stainless steel flange section distortion and change of ovality stainless steel flange ring; In addition to the literature, the latter deformation of two kinds of deformation, still exist on the surface of the stainless steel flange Angle deformation and the change of the stainless steel flange ovality. Both in the former and the latter, education affects the flange welding processing and use. Therefore, it is important to prevent welding deformation of the flange. Enough margin to scrap ware, according to our long-term production practice experience, to prevent the deformation, mainly from the following several aspects. First is groove machining: stainless steel flange flat-fell seam should be processed into groove shape, large diameter welding blank flange welding, can make full use of the material, considering the manufacturing process of its corresponding standards, clearly stipulated in the “lunch with the steel plate welding is allowed,” and then to make 100% flat-fell seam nondestructive inspection milk can. Welding of stainless steel flange, general machining process is: the row of shallow gas cutting blanking and bevel cutting, sanding groove and the French who, according to the technological requirements flat-fell seam welding, flange a nondestructive inspection, correction to eliminate stress a machining heat treatment. In addition, the blank flange of stainless steel welding process, welding sequence does not occur right or as the corresponding anti-deformation measures, lead to the stainless steel flange deformation is too large, all of these in the usual manufacturing process to avoid.

Stainless steel flange during processing, in addition to go through multi-channel heat treatment process, also need to use machining process, the main tool is cutting blades, etc., but for the cutting of the stainless steel flange material is not very simple, here share with you the points for attention during the cutting of stainless steel flange. First of all, should consider when cutting the hardness of the stainless steel flange, and the resulting cutting hard to break, increasing the difficulty of cutting, so should consider three aspects. First, it is according to the stainless steel flange and hardness of various types of blank to select cutting parameter; Second, it is according to the cutting tool material, the welding quality and tool grinding conditions to select the cutting parameter; The thread rolling machine Third, the diameter is according to the parts, precision lathe and machining allowance to choose cutting parameter. Reasonable choice of the cutting parameter of the stainless steel flange size, the size of the cutting parameter will directly affect the production efficiency and processing quality of the stainless steel elbow. So, choose reasonably stainless steel flange cutting when the cutting dosage, can guarantee the production efficiency and processing quality, also can do a good job in the subsequent welding process accordingly.
