Weld Socket Fittings

Weld socket fittings provide a rugged, durable connection for high-pressure piping systems, particularly for small-diameter applications. They feature a recessed socket that accepts plain-end pipe and is secured by a fillet weld around the outside of the fitting. Weld socket fittings are produced using a forging process where the steel is formed under extremely high pressure, which improves the material's grain structure, resulting in high mechanical strength and excellent resistance to high pressure and thermal cycling.

The strength and leak-proof integrity of weld socket fittings make them essential for industries where safety and reliability are non-negotiable. They are widely specified for systems transporting hazardous, high-pressure, or high-temperature fluids and gases.
 

With 30 years of focused experience, our facility is optimized for the high-volume production of quality pipe fittings. We utilize a fleet of over 50 advanced CNC machine tools to ensure every weld socket fitting meets strict dimensional tolerances, guaranteeing consistent fit-up for our wholesale clients. Our streamlined manufacturing process, overseen by a rigorous quality management system, enables us to fulfill both standard and custom orders efficiently.

Packing and Delivery

 

Our commitment to quality is demonstrated by our adherence to an ISO 9001-2015 certified quality management system. All our fittings are manufactured to meet or exceed key international standards like ASME B16.11, which dictates the dimensions, tolerances, and material requirements for forged fittings. This ensures our products are trusted for use in projects globally. To provide our partners with complete confidence, we back our products with a comprehensive 1-year quality guarantee after shipment.

1. What pressure classes are your weld socket fittings available in?
Our weld socket fittings are most commonly produced in Class 3000, 6000, and 9000 to meet the demands of various high-pressure industrial applications, as specified by ASME B16.11.
 

2. What materials are your fittings made from?
We offer fittings in a wide range of materials to suit different service conditions, including carbon steel (e.g., ASTM A105), stainless steel (e.g., A182 F304/316L), and various alloy steels for high-temperature or corrosive environments.
 

3. Does the pipe need special preparation before welding?
No, a key benefit is that pipe ends do not require beveling. The pipe simply needs to be cut square, cleaned, and fully inserted into the socket before the fillet weld is applied.
