Socket weld fittings are a type of pipe connection method that uses a seal welding process. Here are some key points about socket weld fittings:

1. :

   Materials:

   • Carbon steel, alloy steel, and stainless steel are commonly used for socket weld fittings.

   • Standards include ASTM A234 WPB/WPC, ASTM A105 (carbon steel), ASTM A234 WP5/WP9/WP11/WP22/WP91 (alloy steel), and ASTM A403 WP304/304L, WP316/316L (stainless steel)

   • Socket weld fittings involve inserting a pipe into a recessed area of a valve, fitting, or flange.

   • They are mainly used for small pipe diameters (typically NPS 2 or smaller) in what’s known as “small bore piping.”

   • Fillet-type seal welds are applied to join the pipes or valves to other sections of the pipe.

2. Industries and Applications:

   • Socket weld fittings find applications in various industries, including:

     • Oil and gas

     • Petrochemicals

     • Medical science

     • Power stations (electric or nuclear)

     • Environment control

     • Aerospace constructions

     • Fire protection systems

     • Mining slurry

     • Shipbuilding

   • These industries often require higher precision parts and handle high pressures
