Reforming Rim Clamp


Rim Clamps simplify the toughest reforming jobs and are ideal for applications requiring 100% weld and grind under clamping pressure.

Also allows for extremely accurate fit-up of large diameter pipes and shells.

Jackscrews apply pressure on specific high points to precisely reform and align the pipe or shells. Ideal for applications that require 100% weld and grind without releasing clamping pressure to prohibit cracking of partially completed welds.

The clamp can also be used to round the pipe or shell on which it is placed. All surfaces of the Rim Clamp that contact the pipe are made of stainless steel so that this clamp can be used for nuclear and other similar applications.

The Clamp will reform 45,000psi tensile strength pipes up to Schedule 80, with out-of-round conditions up to 2″ (51mm).

Features:

  • EXTREMELY ACCURATE fit-up on large diameter pipe or shells.
  • Hi-Lo—Handles out-of-round conditions up to 2″ (51mm).
  • EASY ALIGNMENT AND REFORMING—Pressure can be applied to the high point of the pipe or vessel to reform it to the required shape.
  • VERSATILE—The clamp can be used for steel or stainless steel applications.
