Pipe Bending Tooling
All Huth tooling is machined to specific tolerances from solid steel. After it is machined, it is gas-carburized and oil quenched to a minimum hardness of 58 Rockwell “C” scale. All Huth tooling is available from shelf stock. However, Huth will manufacture custom tooling to your specification for sizes not listed in this schedule.
Fabricators commonly work with schedule 40, schedule 80 or schedule 10 pipe due to their outstanding strength characteristics. Bending these pipes is easy with the Huth Fabrication bender, as well as other models as well (check the bending capacity specifications for your bender).
