Socket weld flanges are connected to pipes using a single fillet weld executed on the outer side of the flange (different from the slip-on flange type that requires two welds).
According to ASME B31.1, to execute a flanged connection using a socket weld flange, the pipe shall be at first inserted in the socket of the flange until it reaches the bottom of the flange, then it should be lifted by 1.6 mm and finally welded.
This gap shall be left to allow proper positioning of the pipe inside the flange socket after the solidification of the weld.
Socket Weld Flanges are used for small-size and high-pressure piping that do not transfer highly corrosive fluids.
This due to the fact that these flange types are subject to corrosion in the gap area between the end of the pipe and the shoulder of the socket.
Their static strength of socket weld flanges is similar to slip-on flanges, but their fatigue strength is higher due to the presence of a single, instead of double, fillet weld.
We UNIMIX METAL CORPORATION , are one of the Leading, manufactures & suppliers of Socket Weld Flanges.
Socket welding flange, a popular type of pipe flange, was initially developed for use on small-sized high- pressure piping. The fabrication of this type of flange is similar to that of a slip-on flange. However, the internal pocket of a socket weld flange allows for a smooth bore and better fluid flow. When provided with an internal weld, the static strength of this flange is equal to slip-on flange, but the fatigue strength is 50% greater than double welding slip-on flanges. Smooth bore conditions in such a flange can easily be attained without having to bevel the flange face and, after welding, to reface the socket weld flange as would be required with slip-on flanges. For this reason, the internally welded flange is popular in chemical process

This is similar to a slip-on Flange in outline, but the bore is counter- bored to accept the pipe. The diameter of the remaining bore is the same as the inside diameter of the pipe. The Flange is attached to the pipe by a fillet weld around the hub of the Flange. An optional internal weld may be applied in high stress applications. Its biggest use is in high-pressure systems such as hydraulic and steam lines.

A socket weld flange is a type of flange that is used to connect two pieces of pipe together. It is made up of a flange body with a socket, which is a recess that the pipe is inserted into. The pipe is then welded to the flange body, creating a secure connection.
Socket weld flanges are typically used in small-diameter pipes, up to 4 inches in diameter. They are a popular choice for applications where internal welding is difficult or impossible, such as in high-pressure or high-temperature systems.
Relying on our expertise and knowhow in this field we are wellknown as one of the major organization in providing a widespread range of Socket Weld Flanges Well this type of flanges is similar like Slipon flanges in its outline However the bore is counterbored to recognize the pipe The distance across the residual bore is alike as the interior pipe diameter The Socket Weld Flange is close up to the pipe by a clean join around the core of the flange An intended gap weld might be used in high pressure applications In addition the main usage of such flanges is in their premier pressure systems are like
hydraulic and steam lines
