Stainless Steel Weld Neck Flange – High-Precision, Corrosion-Resistant for Industrial Applications
Stainless Steel Weld Neck Flanges (WN Flanges) are fundamental components in industrial piping systems, recognized for their exceptional strength, corrosion resistance, and reliable sealing performance. Manufactured from premium stainless steel alloys including 304 and 316, these flanges are engineered to endure demanding operating conditions, making them ideal for critical applications across various industries.
Superior Design & Performance
The weld neck flange features a long, tapered hub that integrates seamlessly with piping systems, distributing stress evenly across the joint and minimizing pressure concentration. This design enhances structural integrity and enables full penetration welding, creating leak-tight seals essential for high-pressure, high-temperature (HPHT) systems. Our flanges deliver consistent performance and extended service life when handling corrosive chemicals, abrasive fluids, or extreme temperature fluctuations.
Material Specifications & Applications
- 304 Stainless Steel: Excellent general corrosion resistance for food processing, water treatment, and mild chemical applications
- 316 Stainless Steel: Superior resistance to pitting and crevice corrosion for chloride-rich media, marine environments, and aggressive chemicals
Available Specifications
Our stainless steel weld neck flanges are available in comprehensive size ranges, pressure classes (150 to 2500), and finishes to meet specific project requirements.
