Determining Specifications for Shape Templates

1. Specify Mathey Dearman Machine Model (Example: 2SA).

2. Specify size/schedule (wall thickness) pipe branch to be cut. (Example: 8" / 203mm pipe- Schedule 80.)

3. Specify size of main pipe to which the branch pipe will be fitted. (Example: 8" / 203mm pipe actual OD = 8 5/8" / 219mm.)

4. Specify the angle of the cut and whether it is a Saddle or Miter. (See Figure 2.) (Example: 45 degree miter)

5. Specify whether the joint is “Saddle In” or “Saddle On” (See Figure 1).

6. Specify if pipe is to be offset. If the answer is yes, specify how much the pipe is to be offset.


NOTE: The 3SA - 8SA Storage Box is made of plywood reinforced with 1" x 4" Heat Treated Lumber.

Designed to adapt to Customer's Supplied Torch Holder.

(Torch and Torch Rack Sold Separately.)

Part No.: 05.0510.302

Designed to elevate MagnaCut XM Torch Holder to accommodate Plasma Machine Torch or Machine Welding Torch.

(Torch and Torch Rack Sold Separately.)

Part No.: 05.0510.301

Most fabricators are using the MagnaCut XM in conjunction with a Bernard Machine Welding

Torch or Tweeco Tam Welding Torch. These welding torches fit directly into the 1 3/8" / 35mm Torch Holder supplied with the machine.

APPLICATIONS VARY WIDELY:

One application required a stringer weld with .060" Flux Core Wire. Another required a stringer weld with .035" ER70S-6 Welding Wire.

Thicker wall pipes can be cut with the CGM by making multiple passes with Severing Blade Only (or) with the combination of the Beveling Blades and the Severing Blades. While the finish of the bevel is not smooth, it is a practical means of severing heavier wall pipes that are up to 1 1/2" / 38mm thick with Standard Severing and Beveling Blades.

NOTE: The above New CGM Severing Blades are not interchangeable with the Old Style Severing and Beveling Blades.

NOTE: We can also offer Special Steel Discs to replace the Beveling Blades at a fraction of the cost for customers who only need the machine to cut the pipe without beveling.

“Cut Pipe Must Be Aligned”

Process Improvement

Mathey Dearman Chain Clamps align “Schedule 80” and reform “Schedule 40” pipes, elbows, tees

and other fittings within their range, while providing the maximum amount of safety for the welder. Five (5) Distinct Chain Clamp Models, in Carbon and Stainless Steel, are available to accomplish the critical alignment and reforming of pipes and fittings to improve “upstream processes” that have a substantial impact on product quality and performance.

The Original and Light Chain Clamps, with Level and Support Device, are designed to achieve the critical alignment of elbows, tees and other fittings that reduce rework due to poor weld joint alignment.

The Hydraulic Double Chain Clamp is a “specially engineered” clamp for the rapid clamping and alignment of large diameter pipes and shells.

Mathey Dearman Chain Clamps eliminate the need for such items as bottle or house jacks, weld-on lugs and cable hoists that present a safety risk to the pipe fitters and welders. One Chain Clamp covers the range of eight (8) Cage Clamps.

Rim Clamp Accessories


Rim Clamps are “THE CLAMPS WITH MUSCLE” for tough

reforming jobs. Jackscrews apply pressure on specific high points to precisely reform and align the pipe or shells. Ideal for applications that require 100% weld and grind without releasing clamping pressure to prohibit cracking of partially completed welds. The Clamp can also be used to round the pipe or shell on which it is placed. The Clamp will reform pipes or shells to “Schedule 80” and corrects out-of-round conditions up to 2" / 51mm.

NEW - AND SPECIALLY ENGINEERED ‘MEGA RIM CLAMP’ is for aligning and reforming pipe with a high tensile strength (up to 70,000 lbs.), such as P91 Pipe, for wall thickness up to

7/8" / 22mm. The Mega Rim Clamp will correct out-of-round conditions up to 2" / 51mm.

The ‘MEGA RIM CLAMP’ incorporates stronger design to the clamp side walls, Jackscrews with independent pivot pads for uneven surfaces, latching mechanism and extended

Jackbars to reform high tensile strength materials. The amount of added Stabilizer Bars and Flip-Up Jackbars are determined by the diameter of the pipe. Clamp is supplied with Lifting Ring to raise and lower the clamp on the pipe.

Cage Clamps

The Cage Clamp is used to rapidly align one diameter of pipe only. Cage Clamps

are available in several styles for pipes 2" to 60" / 51 to 1524mm and is used as:

• HandLever.

• Ratchet.

• HydraulicModelwith either Tack Type or No Tack Cross Bar.

Straight Cross Bars of the Tack Type Clamp have flared ends so pipes can

be moved easily into position and clamped. When the pipe has been tack welded, the clamp is removed from the pipe and the weld is completed.

N o Tack Cross Bars are arched to permit a full circle weld to be completed without

removal of the Clamp. The No Tack Clamp is used to make welding more efficient and to insure a quality weld. The Cage Clamp is not designed to reform the pipe.

Pipe Fitter's ToolsFlange Line Up Pins – “FLUPs”

FLUPs aid the welder in checking or obtaining critical alignment of flanges to the pipe. FLUPs

can now be used for the rapid alignment of Carbon Steel and Stainless Steel flanges.

Flange Line Up Pins are used by the welder to obtain a quality fit-up and avoid rejection due to inaccurate alignment.

“Flange Bolt Diameter is 5/8"-1 7/8 " / 16-47mm.”

A simple push of the “Thumb-Lock Pin” allows the Flange Pin to quickly release itself from the flange.

The Mathey 'Screw Flange Pins' have evolved into the Wobble Nut FLUP. This FLUP is unscrewed 3/4 turn, tilted and released from the flange in seconds.

NOTE: All parts which contact the flange are now made of Stainless Steel and have replaceable parts for repair.

The Gauge Piano Wires are placed parallel into the weld gap and pushed far enough downward into the gap for the bent end of wire to clear the OD of the pipe. Turn the Gauge Frame 90º to weld gap and release to measure inside “Hi-Lo”™.

Pit Depth Gauge

Pit Depth Gauge {for use with the Quality Control (Q.C.) Welder's Gauge}. The Stainless Steel Gauge measures depth of pitting, weld undercut, pipe OD, “Hi-Lo”™, and determines the height of the weld.

Avoid Weld Failure with The 'HOT BOX'

Higher strength steels and alloy steels are being used in pipelines, fabrication

and construction to increase strength and to reduce cost and weight, increasing the service life. These high strength steels require specialized welding electrodes to join them together. Welding codes require that specialized welding electrodes, which have been exposed to the atmosphere for a period of time, be reconditioned, rebaked and held in a holding oven until it is reissued to the welder.

The exposure of the welding electrode, to the atmosphere for an extended period of time, will influence weld quality. Should the amount of moisture in the welding electrode

become excessive, the potential exists for the introduction of hydrogen into the weld, which will cause cracking and premature failure of the weld. If the electrode should become rusted, the weld quality will also be affected, as this will also lead to the introduction of hydrogen into the weld. It is important to determine the amount of diffusible hydrogen produced during welding when working with higher strength and alloy steels.

Mathey Dearman, Inc. offers thirteen (13) models of ovens, which can be used for reconditioning, rebaking or holding of electrodes or flux with capacities ranging from 18lbs. / 8kg to 794lbs. / 360kg.
