ASME B16.11 – 2021 Edition – Forged Fittings, Socket-Welding and Threaded

ASME B16.11 is a standard published by the American Society of Mechanical Engineers (ASME) titled “Forged Fittings, Socket-Welding and Threaded.” This standard covers the design, materials, dimensions, tolerance, marking, and testing of forged fittings used for socket-welding and threaded connections. These fittings are commonly used in piping systems for various industrial applications.

Key points covered by ASME B16.11 include:

Scope: ASME B16.11 applies to forged fittings used with threaded or socket-welding ends. The standard covers a range of materials and pressure ratings.

Fitting Types: The standard addresses various types of forged fittings, including elbows, tees, couplings, unions, plugs, and bushings, among others.

Materials: ASME B16.11 specifies the materials that can be used for the manufacturing of forged fittings, taking into account factors such as pressure, temperature, and the nature of the fluids being conveyed.

Design Requirements: The standard provides design criteria for forged fittings, ensuring their structural integrity, reliability, and compatibility with piping systems.

Dimensions and Tolerances: ASME B16.11 outlines the dimensions and tolerances for forged fittings, ensuring their compatibility with pipe dimensions and proper assembly within a piping system.

Testing and Inspection: The standard includes procedures for testing and inspecting forged fittings to verify compliance with specified requirements, ensuring their quality and performance.

Marking and Identification: ASME B16.11 provides requirements for marking and identifying forged fittings, allowing users to easily determine their specifications, size, and other essential information.

ASME B16.11 is commonly referenced in industries where threaded or socket-welded connections are prevalent, such as oil and gas, petrochemical, chemical, and power generation. It helps ensure the reliability and safety of piping systems by providing standardized requirements for the manufacturing and use of forged fittings.
