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

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.

Key Features
  • 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

Advantages
  • 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
Applications
  • Chemical injection systems
  • Hydraulic control lines
  • High-pressure utility stations
  • Instrumentation and sampling systems
  • Small-bore process piping
Packaging & Delivery
All socket weld flanges are treated with anti-rust oil and packed in standard shipping packages. Plastic caps protect socket bores and flange faces during transport. Available for delivery within 15-30 working days.
