Core Functions
Provides a secure, permanent connection in piping systems
Distributes stress evenly from flange to pipe to prevent fatigue
Ensures leak-resistant performance under pressure
Key Features
Material: High-grade stainless steel (commonly SS304, SS316, SS316L, or other alloys) with excellent corrosion resistance
Welding Neck Design: Long, tapered hub for butt weld connection to pipe, giving high mechanical strength
Standards Compliance: Manufactured to ASTM/ASME, DIN, EN, JIS, or other international standards
Pressure Ratings: Available in various pressure classes (e.g., 150 #, 300 #, 600 #, etc.) depending on system requirements
Sizes: Wide range of diameters from small-bore to large industrial piping
Surface Finish: Smooth, precision-machined flange face for effective sealing with gaskets
Durability: Excellent resistance to corrosion, oxidation, and chemical attack
Stainless Steel Welding Neck Flanges
Stainless Steel Welding Neck Flanges are premium-quality pipe fittings used to connect pipes, valves, and equipment in industrial piping systems. Their welding neck design features a long tapered hub that is butt-welded to the pipe, providing excellent structural integrity and smooth stress distribution — ideal for critical services, high temperatures, and aggressive environments.
