D711-5056M Mega Rim Clamp 50" - 56"

Mathey Dearman D711-5056M Mega Rim Clamp is a heavy-duty precision alignment and reforming tool designed for quick and efficient pipe fit-up in welding, fabrication, and industrial piping applications. Constructed from high-strength steel with stainless steel contact surfaces for corrosion resistance, this mega rim clamp ensures accurate reforming of out-of-round pipes from 50" to 56" (1270 mm to 1422 mm), correcting conditions up to 2" (51 mm) while keeping all areas accessible for welding and grinding without releasing pressure. Ideal for high-tensile strength X65, X70, and X80 pipes with wall thicknesses up to 7/8" (22 mm), it excels in high-pressure repair and structural fabrication.
