Stainless Steel Weld Neck Flange is a premium piping component with a continuous tapered neck, enabling seamless fusion with pipes for a robust structure. Made of high-grade 304/316L stainless steel (316L excels in chloride and acid resistance), it’s designed for critical extreme-condition applications like offshore oil & gas platforms, refineries, nuclear power plants and heavy chemical facilities.
Its key advantage is optimized stress distribution. The tapered neck design eliminates stress concentration points common in high-pressure, high-temperature (HPHT) environments, avoiding fatigue failure. The seamless weld strengthens connections, reduces fluid turbulence and pressure drop, while raised face/RTJ sealing ensures airtight performance, preventing costly media leakage.
Our flanges comply with ASME B16.5, EN 1092-1 and JIS B2220 standards, ensuring precise dimensions and global compatibility. We offer diverse configurations: neck lengths, pressure classes (Class 150-2500) and sizes (1/2" to 48"). Each flange undergoes rigorous non-destructive testing (ultrasonic, radiographic) to verify weld integrity and quality, meeting industrial safety regulations.
As a leading industrial flange manufacturer, we use advanced forging and machining technologies. Our certified engineers provide end-to-end technical support (material selection, custom HPHT designs), plus efficient global logistics and responsive after-sales service (installation assistance, quality warranty) for a seamless experience.
For critical industrial piping requiring uncompromising strength, reliability and corrosion resistance, our Stainless Steel Weld Neck Flange is the ultimate choice. Partner with us for premium, standard-compliant flanges that boost operational safety and piping infrastructure longevity.
