Stainless Steel Butt Weld Fittings Stub Ends
A Stainless Steel Long Radius Bend is a type of pipe fitting used in piping systems to change the direction of the flow of fluids. Long radius bends are designed to have a curvature radius that is 1.5 times the nominal pipe size (NPS) of the pipe they are connected to.
Stainless Steel: Long Radius Bends are constructed from stainless steel, a corrosion-resistant alloy that is suitable for a wide range of applications, particularly where high corrosion resistance is required.
