Clamping—Self-Centering

Hold pipe and fittings together for tack welding. These clamps can be used to weld two pipes of similar or different diameters, or they can be used to weld a pipe to a flange. With a rugged build, they’re designed for use with heavy pipe.

External Clamping—External clamps work well when you can’t access the inside of your pipe. However, you may need to rotate them during welding to move them out of the way.

Internal Clamping—Internal clamps don’t obstruct welding, making the process faster and simpler. One side of these two-part clamps expands with a knob while the other expands with a hand bar, so you can set them at different diameters to join pipe and flanges of varying sizes.

Thumb Screw Adjustment—Clamps with thumb screws hold fittings or flanges at three separate points—adjust them manually to center the two pieces being joined.

Self-Centering—Self-centering clamps consist of two clamps that share a center line even as you attach each to a different piece of pipe, so the pipes stay aligned with no manual adjustment needed.

Heavy Duty Chain Pipe Welding Clamps


Straight Clamps	Flange Clamps

Adjustable Clamps

The open clamp design permits welding around almost the entire pipe circumference. Secure components with chains and tighten the handles.

Straight Clamps—Straight clamps are for use with two lengths of straight pipe and with reducers.

Flange Clamps—Flange clamps are for flanges and straight pipe.

Adjustable Clamps—Adjustable clamps are for use with straight pipe, elbows, tees, reducers, and risers. They pivot on a hinge to hold components at any angle from 90° to 180°.

Aluminum Body—Aluminum clamps are lighter in weight than iron clamps.

Iron Body—Iron clamps are more durable than aluminum.
