Socket Weld Flange

• Design: A Socket Weld Flange has a cylindrical socket that fits over the end of the pipe. The pipe is inserted into the socket, and a fillet weld is made around the joint to secure it. The flange is then bolted to another flange or fitting.


• Applications: Ideal for small-diameter high-pressure piping systems. It is used where strong joints are required, often in chemical processing, petrochemical, and high-pressure steam applications.


• Installation: The pipe is inserted into the socket, which is then welded around the circumference. This design minimizes the risk of stress concentration and provides a smooth flow path.

Notes:

• Chemical Composition: Indicates the elements present in the material, such as chromium and nickel in stainless steels, which enhance properties like corrosion resistance.


• Yield Strength: The stress level at which a material starts to permanently deform.


• Tensile Strength: The maximum stress a material can withstand while being stretched or pulled before breaking.


• Elongation: Represents the material’s ductility, indicating how much it can stretch before failure
