Description

Stainless Steel (SS) Weld Neck Flange - ½” to 24” - Raised Face - Class 150/300/600/900 & PN16/PN40
Description:

Stainless Steel Weld Neck Flanges are engineered for high-stress and high-pressure piping applications. Featuring a long tapered hub, these flanges provide exceptional reinforcement at the flange-to-pipe junction, reducing stress concentration and ensuring reliable, leak-proof connections.

Constructed from premium stainless steel materials such as ASTM A182 F304 or F316, these flanges offer excellent corrosion resistance, durability, and mechanical strength in demanding environments including petrochemical, power generation, oil and gas, and marine industries.

Available in sizes ranging from ½ inch to 24 inches, these Weld Neck Flanges come with a Raised Face (RF) for enhanced sealing performance with gaskets. They comply with a broad range of pressure classes, including ANSI Class 150, 300, 600, 900, and DIN PN16, PN40, making them suitable for both low and very high-pressure systems.

Manufactured in accordance with international standards ANSI B16.5, ASME, DIN, and EN1092, these flanges ensure precise dimensions, bolt hole alignment, and weld compatibility.

The combination of the tapered neck and robust stainless steel construction ensures minimized flange deformation and extended service life under thermal and mechanical stresses.
