Traditional methods for aligning heavy wall pipe, such as ratchet cable pullers, lugs and bottle jacks are time consuming and inconsistent in the results they achieve, making them unsuitable for the majority of critical pipe alignment applications.

The Double Jackscrew chain clamp reforms schedule 40 pipe on either side of the joint to be welded, and it is also able to exert pressure on the high points of both sides to eliminate “Hi-Low”.

The E-Z Fit Double Chain pipe clamp is an extra heavy duty clamp designed for alignment and reforming of pipes and vessels up to 20' (6M) with up to schedule 80 wall thickness. The double chain clamp will align pipes with any wall schedule.

Many process industries are seeing a resurgence in the need for double chain clamps in their pipefitting operations. In the oil and gas industry, for example, double chain clamping has more recently been used to align and reform steel pipe.

The Mathey Dearman Rim Clamp is built for tough reforming jobs with out-of-round pipe. Our industry-leading rim clamps are ideal for high-pressure pipe repair and other applications requiring 100% weld and grind without releasing clamping pressure.

Mathey Dearman's cage clamp is available in manual hand lever, ratchet, and hydraulic models in either tack or no-tack versions, ranging in sizes for pipes 2" to 60" (51 mm to 1,524 mm). The cage clamps will align pipe through schedule 80.

The ratchet closure system of the Mathey Dearman Ratchet cage clamp provides the extra force needed to align large pipe diameters. The Ratchet cage clamp is available for 14" to 60" (356 mm to 1,524 mm) pipe.

Mathey Dearman’s Hydraulic cage clamp utilizes a rugged hydraulic closure mechanism to create the extra force necessary to align large pipe diameters while also permitting the rapid release of the clamp from the pipe. The Hydraulic cage clamp is available for 16" to 60" (406 mm to 1,524 mm) pipe.

One clamp works on multiple pipe sizes Able to do light reforming to correct ovality in the pipe Able to push or pull the pipe joint together to attain the proper gap Works on carbon steels, stainless steels, and alloys Clamp can work on multiple types of joints Splitframe rim style clamp with turnbuckles, solid steel frame.

Unlike the common and unsafe application of a bottle jack and chain, this purpose-built clamp provides virtually 360 degrees of clamping force for perfect fit-ups.
