Forged fittings standard including ASME B16.11, MSS-SP-79, MSS SP-83, MSS SP-95, MSS SP-97, and BS 3799 standards. They are used to build connection, between nominal bore schedule pipe and pipelines. They are supplied for extensive application range.

Forged fittings standard including typically available in two materials: Carbon steel and Stainless steel. Pressure rating: Class 2000,3000 and 6000 series.End connections of fittings are required to comply with pipe ends, either socket weld to plain end, or NPT to threaded end.

Forged pipe fittings require multiple processes, including material selection, forging, heat treatment, mechanical processing, and inspection. These fittings typically have high dimensional accuracy and surface quality, with a wide variety of fittings that can meet strict engineering requirements and usage environments.

How Many Types of Forged Fittings Standard

The production forged fittings standards include ASME B16.11; MSS SP-83; MSS SP-97; MSS SP-95, etc.

ASME B16.11 Types and Dimension

The ASME B16.11 standard is a production standard for forged high-pressure fittings published by the American Standards Institute. Specifically, the ASME B16.11 has detailed requirements for the material, size, shape, pressure rating, tolerance range, and other aspects of high-pressure forged fittings.
