Product Description
The weld neck flange features an extended, conically tapered hub specifically engineered for butt-welding to pipes or pressure vessel nozzles. This design ensures:
- Full-penetration, circumferential butt welds for optimal mechanical strength
- Metallurgical continuity across the joint
- Gradual stress transition from flange to pipe wall
- Reduced stress concentrations
- Enhanced fatigue resistance under cyclic loading, high temperatures, and pressure
These flanges are essential for critical service applications in:
- Petrochemical processing
- Oil and gas transportation
- Offshore and subsea systems
- Thermal and nuclear power generation
Manufactured to international standards including ASME B16.5, B16.47, and EN 1092, they're available in various pressure classes and facing types. Material selection (carbon steels, austenitic/duplex stainless steels, high-performance alloys) is based on application requirements for corrosion resistance, temperature tolerance, and mechanical performance.
