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.
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.

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