Stainless Steel Butt Welding Fitting
Types of Fittings: Stainless steel butt welding fittings come in various types to accommodate different piping configurations. Common types include elbows, tees, reducers, caps, stub ends, crosses, and lap joint stub ends. These fittings allow changes in direction, branch connections, size transitions, and closure of pipe ends.
Butt Welding: Butt welding is a welding technique used to join stainless steel pipes or components. It involves aligning the ends of the pipes or components, applying heat and pressure, and welding the joint. Butt welding provides a strong and continuous connection with excellent structural integrity.
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.
