Part of CRC-Evans' Standard Welding System, the Heavy-Duty Copper Backup Clamp features a reinforced structural steel frame that deftly handles the large-diameter, heavy-wall pipes typical of offshore projects. The HDCBUC delivers 1.5 times the clamping force of standard clamps, which pushes high-low out to achieve a quality pipe-to-pipe fit. And all functions are wirelessly controlled by the stalking machine operator, which decreases the time for fit-up and eliminates errors such as lowering of the copper shoes during a welding cycle.
