Universal Chain Clamp

Universal Chain ClampUniversal Chain Clamps reform pipe to Schedule 20 and align pipe to Schedule 40. Available in carbon steel chain and stainless steel chain versions to fit pipe from 1” to 36” (25 mm to 914 mm). The versatile design provides the ability to accurately fit-up, weld and grind joints without removing the clamp. The Level and Support Device of the Universal Chain Clamp allows pipe, elbow, tee, flange and other fittings to be safely secured during the alignment and welding process. Although all Mathey Dearman Chain Clamps feature stainless steel Jackscrews, Jackbars and Main Blocks, stainless steel chain should be used on stainless steel or specialty alloy applications to avoid potential contamination.
