This clamping and welding end prep tool can bevel any angle of preparation and square the pipe ends on super duplex stainless steel, P-91, and other hard alloys in a single step.
A portable, ID clamping end prep tool that is designed for prepping hard alloy pipe for welding in situ, especially on oil rigs and in other remote locations, is available from ESCO Tool (Holliston, MA).
The Prepzilla MILLHOG® ID clamping and welding end prep tool can bevel any angle of prep and square the pipe ends on super duplex stainless steel, P-91, and other hard alloys in one step. Featuring one mandrel and eight sets of clamps to fit pipe from 1-1/2 in ID to 8-5/8 in OD, this portable tool weighs only 40 lb and requires no special operator training.
Supplied with cutting blades that transfer heat away from the pipe surface to prevent work hardening and extend blade life, the Prepzilla MILLHOG ID clamping welding end prep tool pulls a thick chip without cutting oils. Generating 1,500 ft-lb of torque at the cutting blade, this rugged tool has a 2 hp air motor supported by dual opposed tapered roller bearings.
