Single Jackscrew Chain Clamp
The Single Jackscrew Chain Clamp reforms the mating side of the weld gap only, and is capable of reforming up to Schedule 40 pipe. The jackscrews of the jackbar exert pressure on the high points of the mating pipe eliminating “Hi-Lo” as pipe and fittings are aligned. Pipe wall thickness to Schedule 80 can be aligned with the Single Jackscrew Chain Clamp.

The level and support device of the chain clamp allows the pipe, elbow, tee, flange and other fittings to be held safely and securely in place during the alignment and welding process. For stainless steel or specialty alloy applications, replace the chain of the standard chain clamp with stainless steel chain. 
 
 
Double Jackscrew Chain Clamp
 The Double Jackscrew Chain Clamp reforms Schedule 40 pipe on either side of the joint to be welded. The jackscrews of the jackbar exert pressure on the high points of both sides of the weld joint to eliminate “Hi-Lo”. Pipe wall thickness up to Schedule 80 can be aligned with the clamp.

The level and support device of the chain clamp allows the pipe, elbow, tee, flange and other fittings to be held safely and securely in place during the alignment and welding process.

For stainless steel or specialty alloy applications replace the chain of the standard chain clamp with stainless steel chain.

Available in steel and stainless steel models to fit pipe from 1" to 54" (25mm to 1372mm).
 
Dearman Light Chain Clamp
The ideal chain clamp for the welder or fitter who does not need to reform elbows, tees or other fittings. The Dearman Light series of Chain Clamps are durable and versatile and, like the original Dearman Chain Clamp, reform up to Schedule 20 and align up to Schedule 40 pipe. The jackscrews in the jackbar give the welder the ability to obtain the optimum fit-up of the pipes or fittings to be joined.

This light-weight clamp is rapidly adjusted to any pipe diameter by pulling the chain through the main block. Precision outside or inside diameter alignment can be quickly obtained without operator fatigue. 
 
 
Universal Chain Clamp
 The Universal Chain Clamp's design gives the welder the ability to accurately fit-up, weld and grind the pipe without removal of the clamp. The level and support device of the chain clamp allows the pipe, elbow, tee, flange and other fittings to be held safely and securely in place during the alignment and welding process.

Replace the chain of the Universal Chain Clamp with stainless steel chain for stainless steel or specialty alloy applications. Available in carbon steel and stainless steel models to fit pipe from 1" to 36" (25mm to 914mm).
 
Double Chain Clamp
 

The Double Chain Clamp is a heavy-duty vessel clamp designed for alignment and reforming of pipes and vessels up to 20' (6M) with Schedule 80 wall thickness. Aligns Schedule 80 pipe and over when no reforming is required.

The extra heavy-duty jackbar and main block provide the brute strength to accomplish difficult reforming jobs. Models 10" to 36" thru 10" to 54" come with level and support device and all other models come with cable hoist. The Double Chain Clamp is available in steel and stainless steel models and is shipped in a wooden storage crate.

 
Hydraulic Chain Clamp
The Hydraulic Double Chain Clamp has a power hydraulic tensioning mechanism incorporated into its design. The hydraulic cylinder of the hydraulic tensioning mechanism, which has a 5" (127mm) stroke, applies up to 10,000 lbs (4535kg) of tension to the standard Double Chain Clamp. Rapid and effortless tensioning can be applied to the Double Chain Clamp to close it on the pipe.

Hydraulic pressure is supplied to the cylinder by a hand pump with reservoir. The clamp is specifically designed to align pipe up to Schedule 120 and reform pipe to Schedule 80.
 
 
Quik Fit Clamp
The Mathey Dearman Quik-Fit Clamp offers the most advanced method of achieving quick, easy and precise fit-ups. The Quik-Fit is a tack-type clamp that requires no special training to use.

Quik-Fit is available in 3 sizes to cover a range of 1" to 12" pipes, and can be used on both carbon and stainless steel without adding special shoes or screws. The clamp will not only align pipe to pipe, pipe to fitting, pipe to tee, or pipe to flange, but can also be used to adjust for pipe "Hi-Lo".

The light weight and simple design makes the Quik-Fit Clamp ideal for applications where "out-of-round" conditions do not exist.
