Upgrade Your Piping System with Long Weld Neck Flanges

Engineered for Strength, Durability, and Precision

Long Weld Neck (LWN) Flanges are the ideal choice for high-performance piping systems, delivering superior strength, reliability, and long-term performance. Unlike standard weld neck flanges, the extended hub acts as an extension of the pipe bore, providing enhanced structural integrity and improved stress distribution.

Versatile Applications, Exceptional Performance

Designed for use in pressure vessels, columns, and barrels, our Long Weld Neck Flanges are available in a wide range of materials, including ASTM A105, ASTM A350 LF2, and ASTM A694. With sizes ranging from 1/2″ to 24″, they integrate seamlessly into demanding piping systems across various industrial applications.

Engineered for Maximum Performance

The extended hub design ensures a strong, leak-resistant connection, while both Heavy Barrel (HB) and Equal Bore (E) configurations provide additional reinforcement for superior durability. Choose our Long Weld Neck Flanges to maximize the performance, safety, and service life of your piping system with uncompromising quality and precision.
