Weld neck flanges feature a tapered hub design that effectively transfers stress to the pipes, reducing high-stress concentration at the flange base. Manufactured from forging and welded directly to pipes, these flanges provide exceptional structural strength and reliability.
The raised face design concentrates pressure on a smaller gasket area, significantly enhancing the pressure containment capability of the joint. This configuration supports various gasket designs including flat ring sheet types and metallic composites.
- Enhanced stress distribution through tapered hub design
- Superior pressure containment with raised face configuration
- Compatible with multiple gasket types for versatile applications
- Manufactured to strict ANSI B16.5 dimensional standards
