DN15-DN600 stainless Steel Weld Neck Flange

DN15-DN600 stainless Steel Weld Neck Flange is a premium, high-integrity pipe connector designed to be butt-welded directly to a pipe or fitting. Its defining feature is a long, tapered hub that distributes stress evenly and resists distortion, making it the industry standard for high-pressure, high-temperature, and hazardous systems.   Specification: 1. DN15-DN600 2. Pressure Classes: Commonly rated from Class 150 to Class 2500 3. ·Available in Raised Face (RF), Flat Face (FF), and Ring Type Joint (RTJ) depending on the required gasket seal. 4. Materials: carbon steel (e.g., ASTM A105), stainless steel (304/316), and other alloy steels. 5. For example: SS316（UNS S31600 / 1.4401 / SUS316）,chemical composition: (wt%)，ASTM/EN standard: C：≤ 0.08 Si：≤ 1.00  Mn：≤ 2.00 P：≤ 0.045 S：≤ 0.030 Cr：16.0–18.0 Ni：10.0–14.0 Mo：2.0–3.0   Features: · High Joint Integrity: The butt-welded connection prevents leakage and ensures maximum structural strength. · Reduced Turbulence: The flange's b…
