Alloy steel socket weld pipe fittings are available in grades F5 / F9 / F11 / F12 / F22. F means forging, so that we can also call it as forged steel fittings which standard is ASME B16.11
ASTM A182 standard specification covers forged or rolled alloy and stainless steel pipe flanges, forged fittings, and valves and parts for high-temperature service. After hot working, forgings shall be cooled to a specific temperature prior to heat treatment, which shall be performed in accordance with certain requirements such as heat treatment type, austenitizing/solution temperature, cooling media, and quenching.
Zizi Engineering is one of the top manufacturer, exporter and supplier of steel pipe fittings & flanges which are available in various sizes, dimension and shapes according to our client’s requirement.
Specification
Standard | ASTM A182, ASME B16.11 |
Size | 1/8” NB to 4” NB |
Pressure | Class 2000lbs, 3000lbs, 6000lbs, 9000lbs |
Type
Socket Weld Elbow
There are two types that 90 degree elbow and 45 degree elbow.
Socket Weld Tee & Cross
Compare run pipe with branch pipe size, we can divided into socket weld equal tee & cross and reducing tee & cross.
Socket Weld Cap
It is used to insert a pipe into socket and then weld it for sealing the end of pipeline.
Socket Weld Coupling
There are four types that full coupling, half coupling, straight coupling and reducing coupling. It is used to connect two pipes or tubes whatever the diameter size is same or not.
Socket Weld Union
It is a pipe attachment detail in which a pipe is inserted into a recessed area of a Valve, fitting or flange.
