Single Jackscrew Chain Clamp

General Information

The Single Jackscrew Chain Clamp reforms the mating side of the weld gap and is capable of reforming up to Schedule 40 pipe.* Each jackbar is equipped with its own jackscrew to exert pressure on the high points of the mating pipe, eliminating “Hi-Lo” as pipe and fittings are aligned. Pipe with wall thickness to Schedule 80 can be aligned with the Single Jackscrew Chain Clamp.* The Level and Support Device of the Chain Clamp allows elbows, tees, flanges and other fittings to be held safely and securely for alignment and welding. The Single Jackscrew Chain Clamp is available in nickel plated carbon steel chain and stainless steel chain versions to fit pipe from 1” to 54” (25 mm to 1372 mm) in diameter. Although all Mathey Dearman Chain Clamps feature stainless steel Jackscrews, Jackbars and Main Blocks, stainless steel chain should always be used for stainless steel and specialty alloy applications to avoid potential contamination.
