ASME B16.25 – 2022 Edition – Buttwelding Ends

ASME B16.25-2022 is a standard published by the American Society of Mechanical Engineers (ASME). Its full title is “ASME B16.25-2022: Buttwelding Ends.” This standard specifies the dimensions, manufacturing requirements, and inspection methods for buttwelding ends used in piping systems.

Specifically, ASME B16.25-2022 covers the following aspects:

Dimensions and Tolerances of Ends: It specifies various dimensions and tolerance requirements for buttwelding ends, including diameter, wall thickness, length, etc.
Manufacturing Requirements: It provides guidance on the manufacturing process of buttwelding ends, including material selection, fabrication, welding methods, etc.
Inspection and Acceptance: It stipulates the inspection methods and acceptance criteria for buttwelding ends during the production process to ensure compliance with specified quality requirements.
Marking and Identification: It requires proper marking and identification of buttwelding ends to facilitate their use, installation, and maintenance.

The ASME B16.25-2022 standard plays an important guiding role in the design, manufacturing, and installation of piping systems. It ensures the quality and dimensional consistency of buttwelding ends, thereby improving the reliability and safety of piping systems.
