Mathey Dearman D231-SC 1" - 12" Sturdi-Clamp (1 each)

 

 

The ideal chain clamp for the welder or fitter who does not need to reform elbows, tees or other fittings. The Mathey 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.

Mathey Dearman Specializes In Pipe Welding

Heavy industry discovered decades ago that the best way to do a job with quality and speed was to specialize. It was better to have a person and tool that did something very well, rather than letting unskilled people with general tools attempt to do everything. Because of this, American industry has made great strides in nearly every endeavor it has undertaken. This is especially true in the heavy industries of mining, gas, petroleum and other ambitious projects that require huge amounts of expertise and large, complex equipment and infrastructure to operate. Pipes are often a key component of this kind of work, and it’s here that Mathey Dearman delivers.

Mathey Dearman for Big Projects

The Mathey Dearman company has its roots in working pipes, something that it started in 1936. Since then, the company has grown, incorporating many other specializations including Tim Dearman’s innovative welding technology in the 90s. Today, Mathey Dearman is one of the world’s foremost companies for this sector of the industry. Working with pipe is not something that’s often talked about, but in many industries, the proper construction, assembly and maintenance of pipes is critical to a successful business. This is one of those areas where expert staff and specialized equipment play an important role, and Mathey Dearman delivers.

Pipe Jobs Done Right

The Mathey Dearman D231 light chain clamp is an incredibly useful tool for people that need to work and weld pipes. Welding pipe and fittings can be done without needing to remove the clamp itself. It can reform pipe to schedule 20, but can align pipe to schedule 40. If you need to apply pressure between clamp jackbars, an add-on jackbar can be added provide the pressure. Jackscrew pads can independently pivot if you’re working on uneven surfaces for added convenience. The D231 is made out of carbon steel, so it is incredibly durable, but it is also adaptable. If you need to use it with stainless steel or have other speciality alloy applications, the carbon steel roller chain can be swapped out with a stainless steel chain.
