ASTM A403 ASME B16.9 BW Stainless Steel Butt Welding Fittings
Product Information
Stainless steel butt weld fittings provide a robust and durable connection between pipes. The welded joint has strength comparable to the pipes themselves, ensuring long-lasting performance even under high-pressure or high-temperature conditions.
Stainless steel butt weld fittings offer excellent resistance to corrosion, making them suitable for use in corrosive environments or media. The stainless steel material provides protection against rust, oxidation, and chemical attack, ensuring the fittings maintain their integrity over time.

Stainless Steel Butt Welding Fitting
The butt welding fittings are made of pipe, tubing, plate, or forging. The fittings can be made from a hot forming or cold forming process, in welded or seamless pipe. It may be a standard fitting that meets all dimensional requirements of ASME B16.9 and or customized fitting in conformance with ASME B16.9, except that dimensional requirements are as agreed between customer and manufacturer.
The standard butt welding fittings can be furnished in various forms covering elbow (90°, 45°, long radius, short radius, 3D radius, reducing), 180° return (long radius,short radius), tee & cross (straight or reducing), lap joint stub end (long pattern , short pattern), cap, reducer (concentric or eccentric). The wall thickness of the fitting is often specified by a schedule number, which is a dimensionless number that is widely used as a convenient designation for use in ordering pipe and fittings.
