Internal fit-up clamp

Ultra Qwik Clamp

Clamp Champ

DX Clamp

Chain clamps offer ‘does all’ fit-up work, and are generally more economical than other clamps. They handle pipe-to- pipe, pipe-to-flange and to-fitting. The range is normally greater than other clamps. For instance, Sumner Clamp Champ has a range of 1 to 16" or 10 to 36". While chain clamps are more universal to use, they tend to take longer to operate than the other clamps because there are more adjustments. Chain clamps are available in stainless or carbon models.

A similar style of clamp is the DX Clamp, which has the same 4-, 8- and 12-o’clock adjustment positions, but the arms are made of dropped forged steel.

Available in four styles from 1 to 14" pipe range, the DX Clamp tends to be popular in Central Europe.

Other clamps in the Sumner range can be found on the company’s website.

Fitting up flanges can be a challenge, but the Sumner Internal Clamp easily handles 2 to 12" slip-on and weld neck styles flanges. The clamp uses two expanding mandrels that have stainless contact points so that the tool can be used on carbon or stainless pipe and flanges. One handle is for mounting the tool in the pipe and positioning it to the axis of the pipe. The second adjustment aligns the flanges to the end of the pipe. The internal clamp is a fast and accurate solution for flange fit-up work.
