Flow Coupling

Flow Coupling

Flow Couplings are available in 3 to 20 foot lengths, adequately covering the area most generally affected. Couplings are manufactured in either alloy steel heat-treated for maximum erosion resistance, and strength, (Hardness 30-36 RC, 110,000 MYS) or from alloy steel or stainless steel heat treated for maximum corrosion resistance, based on NACE Specifications. (Hardness is 18-22 RC, 80,000 MYS) Flow Couplings are available with special outside diameters or threads, upon request.
