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.
