AAP socket weld flange, 2"

This AAP socket weld flange is made from carbon steel to ANSI B16.5 Class 300. It is supplied in 8 sizes from 1/2" (15mm) to 4" (100mm).

A socket weld flange has a recess that the pipe is pushed into before it is fillet welded around the outside. It is used on small bore pipework. Forged steel flanges are commonly specified in the oil, gas, petrochemical and mining sectors, where pressure, temperature and safety considerations are higher. They are hot forged and then machined. A105 forgings are not recommended for prolonged use above 427 °C.

Key specifications

Choosing the right option

Check the pipe outside diameter against the socket size before ordering, and leave the expansion gap your welding procedure calls for. Match the standard and table or class to the mating flange and compare the drilling dimensions, because flanges made to different standards are not interchangeable. Gaskets and bolting are not included.
