Stainless Steel DIN 2631 PN6 Weld Neck Flanges

Alloy Steel DIN 2631 PN6 Weld Neck Flanges

Alloy 20 DIN 2631 PN6 Weld Neck Flanges

**DIN 2631 PN6 Weld Neck Flanges** are Pressure Class 6 rated to 6 bar (87 psi) and offer sizes from DN10 through DN1000. These flanges are most commonly fabricated from carbon steel (e.g., C22.8), stainless steel (e.g., 1.4301 or 1.4571), or alloy steel, based on use. The weld neck type has a long taper hub that progressively relieves stress from the flange to the pipe, reducing thermal and mechanical fatigue risks. These flanges are butt-welded connections and create solid, permanent joints with high sealing integrity.
