Socket Welding Flanges — High Integrity Joints | Ideal for Small Bore High-Pressure Systems

Socket Welding Flanges are designed for small-diameter, high-pressure piping systems, offering a strong and smooth bore connection. The pipe is inserted into the flange’s socket end and then fillet-welded around the hub, creating a reliable, leak-proof joint that ensures smooth flow characteristics and enhanced fatigue resistance.

Standards & Pressure Ratings

Socket welding flanges are manufactured according to international standards to ensure compatibility and safety:

• ASME B16.5 — Available in Class 150, 300, 600, 900, 1500
• DIN / EN 1092-1 — PN6 to PN40 depending on material and application
• Available in Raised Face (RF) or Flat Face (FF) configurations

Key Features

• Strong & Reliable Connection — Socket welding design provides excellent structural integrity for high-pressure applications.
• Smooth Bore Transition — Ensures minimal turbulence and pressure drop, ideal for critical flow systems.
• Compact Design — Perfect for small bore lines where space is limited.
• Standardized Dimensions — Fully compatible with ASME, DIN, and EN flanges and pipe standards.
• Material Versatility — Available in carbon steel, stainless steel, and special alloys for different environments.
• Raised Face Options — For improved sealing in pressurized systems.
