Flange Types & Design Features
Standard Weld Neck Flanges
Features a long tapered hub welded directly to the pipe, providing reinforcement and preventing leakage. The tapered design facilitates smooth flow transition and reduces stress concentration at the joint.
Long Weld Neck Flanges (LWN)
High-hub flanges designed to transfer stress to the pipe, minimizing stress concentration at the flange base. Primarily used in pressure vessel construction as nozzles, eliminating the need for additional welding and providing integral reinforcement.
Reducing Weld Neck Flanges
Features a reducing diameter neck for welding to smaller diameter pipes. Ideal for installations with limited space, effectively replacing the need for separate reducer fittings and standard flanges.
Manufacturing Process
These alloy steel flanges are manufactured using advanced forging processes to ensure structural integrity and dimensional accuracy throughout production.
