Weld Neck Flange Types
Standard Weld Neck Flange
Also known as tapered hub flange or high-hub flange, designed to transfer stress to connected pipes and reduce high-stress concentration at the flange base. Available in two designs for pipe connections and process plant applications.
Long Weld Neck Flange (LWN)
High-hub flanges engineered for optimal stress transfer to pipes while minimizing stress concentration. Primarily used as pressure vessel nozzles, eliminating additional welding requirements and providing integral reinforcement.
Reducing Weld Neck Flange
Features a reducing diameter neck for welding to smaller pipes, functioning as a reducer fitting. Ideal for space-constrained installations where traditional reducer configurations are impractical.
Manufacturing Process
Our alloy steel flanges undergo rigorous manufacturing processes including forging, precision machining, and comprehensive quality testing to ensure dimensional accuracy and material integrity.
Applications
- Water distribution systems
- Oil and gas pipelines
- Chemical processing plants
- Food production facilities
- Power generation systems
- Marine and offshore installations
