UNMARKED SA A105 1954 B16.5 Pipe Flange

Description:

The UNMARKED SA A105 1954 B16.5 Pipe Flange is used in industrial piping systems to connect pipes, valves, pumps, and other equipment in high-pressure fluid handling applications. Commonly installed in oil and gas facilities, chemical processing plants, power generation systems, and water treatment equipment. Maintenance teams and system integrators use this part for repair, retrofit, or replacement of carbon steel flanged piping connections in industrial process systems.

Applications:

The UNMARKED SA A105 1954 B16.5 pipe flanges are used in industrial piping systems requiring secure, leak-resistant connections under elevated pressure and temperature conditions. They are commonly found in oil and gas pipelines, petrochemical plants, refineries, steam systems, water treatment facilities, and power generation equipment. The flange is manufactured from forged carbon steel conforming to ASTM/ASME SA A105 material specifications and ASME B16.5 dimensional standards, making it suitable for connecting pipes, valves, pumps, and process equipment in demanding industrial environments. ASME B16.5 covers flanges from NPS 1/2 through NPS 24 and pressure classes from 150 to 2500.
