Critical Alignment
The tolerance for misalignment of pipe inside or outside diameters is becoming increasingly critical as companies use automated welding processes, thinner wall pipe and attempt to improve efficiency of 
flow in the pipe or reduce deterioration of the pipe wall. Thousands of dollars in labour are lost annually by companies continuing to use old fashion methods, such as weld on lugs, hydraulic bottle jacks or ratchet cable pullers, to critically align pipe ends. Companies today cannot afford the loss in productivity or have their product rejected as it fails to meet the alignment criteria.
Mathey-Dearman clamps (or pipe fit-up tools) are designed to align and reform pipes, elbows, tees and other fittings within their range, while providing the maximum amount of safety for the welder. Mathey Dearman Inc offers 13 different models of clamps to achieve critical alignment of pipe ends. These clamps are designed to achieve the critical alignment of the outside or inside diameter of the pipe with little or no loss of labour hours. Fits pipe diameters of 3/8" (9.5mm) to 20ft (6M)
