Features: Our pipe bending sets are built to last. For Hydraulic Pipe Bending Machines 6-20, 16-30, 22-36, 32-42, 48-60 Full bending sets, dies (only), and liner sets are available for use with all standard bending machines, for pipe diameters from 4 inches to 60 inches. Bending sets and dies are available bare or with linings, to correspond to the coating on the pipe (see bending set recommendations below). Liners can be supplied as spray, poured or strip urethane, copper, brass or stainless steel. A separate bending set (or die only for the maximum diameter the bending machine will accept) is required for each diameter of pipe. Standard bending sets will accommodate pipe manufactured to API-5L standards. Special order bending sets and dies are available for non-standard diameters and/or pipe coatings.
