Pipe Bending Sets:

 pipeline suppliesAll Darby Bending Machines require a bending set and/or bending die (Bare or Lined) for bending a desired pipe size. A bending set and/or bending dies are required for each diameter of pipe that is bent. The largest pipe size in each pipe-bending machine requires a die only for bare pipe. Coated/lined pipe requires liners on all bending set pieces or bending machine contact points (e.g. stiff back bed, pin-up bed).

All bending sets are manufactured oversized to protect anti-corrosion coating on the pipe. If a thin-film epoxy coating is used as an anti-corrosion coating, a lined bending set is necessary.

All bending sets are designed and manufactured to conform to all API-5L pipe sizes.
