Class 150 Forged Carbon Steel Socket Weld, Raised-Face Flange for Schedule 160 Pipe
Class 150 A105/SA-105 Socket Weld Flange for Schedule 160 Pipe
The Class 150 ASTM A105 / ASME SA-105 ASME B16.5 Forged Carbon Steel Socket Weld Raised-Face Flange for Schedule 160 Pipe provides a compact, durable connection for heavy-wall industrial piping systems. Combining forged carbon steel construction, a precision-machined socket, and raised-face sealing surface, this flange delivers dependable performance in demanding commercial and industrial piping applications.
ASTM A105 / ASME SA-105 Forged Carbon Steel
Manufactured from ASTM A105 / ASME SA-105 forged carbon steel, this Class 150 socket weld flange provides excellent mechanical strength, toughness, and durability. A105/SA-105 is widely specified for pressure-containing components used in oil and gas, petrochemical processing, refineries, power generation, chemical processing, manufacturing, utilities, and industrial process piping systems.
The Class 150 designation represents an ASME pressure class rather than a maximum working pressure of 150 PSI. Actual allowable pressure depends on material, operating temperature, and applicable pressure-temperature ratings.
Socket Weld Design for Schedule 160 Pipe
A socket weld flange incorporates a recessed socket designed to receive the connecting pipe. The Schedule 160 pipe is inserted into the socket, positioned with the required installation clearance, and permanently secured using an external fillet weld.
Schedule 160 identifies a heavy pipe wall thickness. For a given nominal pipe size, increasing the pipe schedule reduces the inside diameter while the outside diameter remains unchanged. The socket is therefore sized for the applicable nominal pipe outside diameter.
Raised-Face Flange Construction
The raised-face (RF) flange features an elevated gasket seating area surrounding the bore. Concentrating bolting force over this gasket area helps establish a dependable seal between compatible mating flanges.
Manufactured to applicable ASME B16.5 requirements, these Class 150 forged carbon steel flanges provide standardized dimensions and pressure-temperature ratings.
When ordering, verify nominal pipe size, Schedule 160 pipe dimensions, socket size, Class 150 rating, raised-face configuration, A105/SA-105 material, and ASME B16.5 requirements for reliable industrial piping system compatibility.
