ASTM A182 ASME SA182F347L Weld Neck RF Forged Flange
Description
ASTM A182 F347 Weld Neck Flange is a high-performance butt-welded flange made of austenitic stainless steel (UNS S34700). It complies with the ASTM A182 high-temperature forging standard and the ASME B16.5 dimensional specification. It has excellent high-temperature oxidation resistance, intergranular corrosion resistance and high mechanical strength.
It is widely used in petrochemical, electric power and high-temperature steam pipeline systems. It is suitable for harsh working conditions with pressure levels of Class 150 to 2500. Its long-neck tapered design can effectively disperse stress and ensure sealing reliability under high-pressure environments.
