Weld Neck Flange Design Features
Weld neck flanges, also known as tapered hub flanges or high-hub flanges, are engineered to transfer stress to connected pipes, significantly reducing high-stress concentration at the flange base. These forged components feature a round fitting that extends beyond the circumference rim and are permanently welded to pipes for maximum integrity.
Long Weld Neck Flanges (LWN)
Long weld neck flanges serve as high-hub flanges specifically designed to transfer stress to the pipe while minimizing stress concentration. Primarily used in pressure vessel construction as nozzles, LWN flanges attach directly to vessels, functioning as integrally reinforced nozzles that eliminate additional welding seams and provide built-in reinforcement.
Reducing Weld Neck Flanges
Reducing weld neck flanges feature a neck with decreasing diameter to accommodate smaller pipe sizes. These specialized flanges enable diameter reduction within the pipeline system while saving valuable space in crowded installations compared to traditional reducer fittings.
Application Benefits
- Superior corrosion resistance in marine and chemical environments
- Enhanced stress distribution and reduced concentration points
- Space-saving design for compact installations
- Direct vessel attachment capability for pressure applications
- Comprehensive size range from 1/2" to 48"
- Multiple pressure class options up to 2500
