UNMARKED SA105 466 B16.5 PIPE FLANGE

Description:

The UNMARKED SA105 466 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:

UNMARKED SA105 466 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. Manufactured from forged carbon steel ASTM A105 material and conforming to ASME B16.5 dimensional standards, these flanges are designed for use with valves, pumps, and process piping in demanding industrial environments. Class 300 flanges are widely used for medium- to high-pressure applications and are available in weld neck, slip-on, blind, threaded, and socket weld configurations.
