Forged fittings are utilized for connecting pipes, valves, pumps, and other equipment’s to make a piping system with a diameter of 1/8 to 4-inches in size.
There are two kinds of forged fittings, threaded fittings and socket-weld fittings. Socket-weld fittings connect to pipes using fillet welding while in threaded fittings, the pipe is screwed to the fittings.
It is constructed using solid steel blocks that in accordance with the tolerances established by the applicable standards and then machined to achieve the required final shape. The fitting class is the maximum pressure that the unit is able to withstand.
High pressure Forged fittings are created by connecting two forged fittings and sealing them with a gasket.
The following table is a brief introduction for Forged Fittings. The specific requirements about the Forged Fittings, welcome to contact and talk more !

Forged fittings are manufactured to meet various standards set by organizations such as ASTM, ASME, MSS, and API. The following are some common standards used for forged fittings:
| Standard | Description |
| ASTM A105 | Standard specification for carbon steel forgings for piping applications |
| ASTM A182 | Standard specification for forged or rolled alloy and stainless steel pipe flanges, forged fittings, and valves and parts for high-temperature service |
| MSS SP-83 | Class 3000 and 6000 Pipe Unions, Socket Welding and Threaded (covers forged steel fittings) |
| MSS SP-95 | Swage(d) Nipples and Bull Plugs (covers forged steel fittings) |
| ASME B16.11 | Forged fittings, socket-welding and threaded (covers both carbon and alloy steel fittings for high-pressure and high-temperature service) |
| BS3799 | Specification for steel pipe fittings, screwed and socket-welding for the petroleum industry |
Coating for forged fittings is mainly with galvanizing, anti-rust oil ....
