Pneumatic internal line up clamp

The internal line up clamp is a device to fix the pipe ends of two pipes from the inside of the pipe before the pipe ends are welded, the high-low effect after aligning is usually less than 1~2mm.

Deping Technology offer a variety of pneumatic internal line up clamp, for example: internal clamp with copper shoes for GMAW welding, internal clamp with purge system (air dam) for TIG welding, internal clamp for pipe prefabrication, as well a laser and camera system for root welding inspection can be connected to the rear part of internal clamp. In addition, per control mode, pneumatic line up clamps can be categorized as full pneumatic type and pneumatic + electrical type.

Deping Technology developed multiple cylinders pneumatic internal line up clamps, it is specially for small pipe size welding, for example: 6in pipe, convention internal clamp could not generate high clamping force due to small cylinder area, in this case multiply cylinders can ensure strong support strength in whole process of welding.
