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 superior performance in demanding applications.
The raised face design concentrates pressure on a smaller gasket area, significantly enhancing the joint's pressure containment capability. This configuration supports various gasket types including spiral wound and double jacketed designs.
- Enhanced pitting corrosion resistance in chloride environments
- Available in sizes from 1/2" to 24" with Class 150 pressure rating
- Compatible with various gasket designs for optimal sealing
- Manufactured to strict ASTM and ANSI standards
- Ideal for chemical processing, oil & gas, and industrial applications
