ASME B16.5 ASTM A105 Carbon Steel Socket Weld Flange Class 150-2500 Forged High Pressure Piping

The Socket Weld Flange is a specialized forged carbon steel piping component designed for small-diameter, high-pressure applications. Manufactured from ASTM A105 forged carbon steel, this flange features a socket bore into which the pipe is inserted before being fillet welded. This design provides excellent flow characteristics and is widely used in chemical injection, hydraulic, and high-pressure utility systems.

• Socket Bore Design: Counter-bored socket accepts the pipe end with a gap to prevent weld-induced stress at the pipe face
• High-Pressure Rated: Ideal for small-bore piping operating at Class 150 through Class 2500 pressure ratings
• Forged Carbon Steel: ASTM A105 material delivers exceptional strength and impact resistance
• Smooth Internal Flow: The socket design eliminates flow restrictions and turbulence at the connection point
• ASME B16.5 Compliant: Manufactured to rigorous ASME/ANSI B16.5 dimensional specifications

• Superior high-pressure performance in small-diameter applications
• Lower risk of weld penetration into the bore compared to slip-on flanges
• Internal socket gap compensates for thermal expansion during welding
• Excellent fatigue resistance under cyclic pressure loading
• Widely used in chemical injection, hydraulic, and instrument lines

• Chemical injection systems
• Hydraulic control lines
• High-pressure utility stations
• Instrumentation and sampling systems
• Small-bore process piping
