A socket weld union is a weld used when attaching socket flanges to iron pipe. The socket flange allows two different-diameter pipes to be connected together and retain a high-flow characteristic. Exactly as the name implies, the socket weld union actually welds a pipe into a recessed socket fitting in the socket flange, creating a high-strength socket weld union capable of withstanding high pipeline pressure without connection failure. Once the pipe is pushed into the flange, the socket weld union is used to surround the outside diameter of the pipe, fusing the two components together as a single component. The weld varies from a common butt weld in that it surrounds a small-diameter pipe where it enters a larger-diameter pipe, instead of simply joining two equally-sized surfaces together. When making a socket weld union, it is imperative that the inner pipe not be pushed completely into the larger pipe so that it bottoms out in the socket. Failure to pull the inner pipe slightly off of the bottom surface of the socket can result in stress failure of the socket and the weld. This damage occurs when the heat from the welding procedure causes the two pipes to expand. Without a small gap between the bottom of the inner pipe and the bottom of the socket, the two could make contact and push against each other, thereby compromising the integrity of the socket weld union.

When selecting a stainless steel flange connection with fasteners, pipeline operating pressure, operating temperature ought to be considered at the same time, medium type and gasket type and other factors. Gasket type and operating pressure, operating temperature, directly to the fastener material strength of duplex stainless steel flange requirements are put forward. For example, the spiral wound gasket seal of low toxic medium pipeline flange connection, although the pipeline operation pressure and temperature is not high, but because of the spiral wound gasket needed to form the initial seal than pressure, which requires fastener load is big, Therefore, in this case requires fasteners with high strength alloy steel materials. Alloy steel stud shall adopt high quality steel. The material mark after all should add letters A, such as 35 crmoa, 25 crmova according to different structure, the bolt can be pided into hexagon head bolts and stud (also known as the stud) two kinds, the stud is pided into two kinds of harness and the harness. Hexagon head bolts: often used with stainless steel flat welding flange and non-metallic gaskets with milder conditions for operation. Commonly used material is BL3 or hex head bolt is Q235B; Stud: often used with butt welding flange at the operating condition is harsh working conditions, among them, because there is no cross section shape on the harness type stud, so its bearing capacity is strong. Rather than type harness stud is relatively weak bearing capacity. Nut materials often according to and cooperate with bolt material, these combinations have provisions in the general standard. Under normal circumstances, the nut material should be slightly below the bolt, and ensure the nut hardness is lower than bolt hardness HB30 around.

There are three kinds of flange sealing surface model: planar seal face, is suitable for the occasion of pressure is not high, medium non-toxic; Concave-convex sealing surface, suitable for pressure slightly higher occasion; Mortise sealing surface, suitable for flammable, explosive, toxic medium and high pressure situation. Gasket is a kind of can produce plastic deformation, and has certain strength rings made of materials. Most gaskets from non-metallic plate cutting down, or produced by professional factory in accordance with the provisions, the size, the material of asbestos rubber sheet, asbestos board, PE board, etc.; Also useful sheet metal (tin, stainless steel) will be made of asbestos etc. Nonmetal material wrapped metal gasket. Another with steelskin belt with asbestos tape winding of spiral wound gasket. Ordinary rubber gasket is suitable for the occasion of temperature below 120 ℃; Asbestos rubber gasket suitable for vapor temperature below 450 ℃, the oil temperature is below 350 ℃, pressure is lower than 5 mpa, for general corrosive medium, the most commonly used is acid-proof asbestos board. According to the connection parts of flange and flange can be pided into the container. According to the structure, special steel flange with integral flange, flange and threaded flange. Common integral flange are flat welding flange and butt welding flange. It can be made of casting and become, also can be made up of threaded connection or welding. By a flange (flange, flange connection to be), a gasket and a number of bolt and nut. The gasket in between the two flange sealing surface and tighten nut, washer on the surface of a pressure deformation after reaching a certain value, fill and seal surface uneven, not to join together. Flange connection is a detachable connection.
