Elevate Your Piping System with Long Weld Neck Flanges

Engineered for Strength, Durability, and Precision

Long weld neck flanges (“LWN”) are the superior choice for your piping system, offering enhanced performance and reliability. Unlike standard weld neck flanges, the extended neck (tapered hub) of the LWN acts as a boring extension, providing unparalleled strength and stability.

Versatile Applications, Exceptional Results

Designed for use on vessels, columns, or barrels, these flanges are available in a range of materials, including ASTM A105, ASTM A350 LF2, and ASTM A694. With sizes ranging from ½” to 24″, you can trust that our long weld neck flanges will seamlessly integrate with your specific piping requirements.

Engineered for Optimal Performance

The extended neck design of the LWN flanges ensures a secure, leak-proof connection, while the heavy barrel (HB) and equal barrel (E) types offer additional reinforcement for enhanced durability. Invest in the best for your piping system and experience the unparalleled quality and reliability of our long weld neck flanges.
