Industry’s Largest Zap-Lok Pipe Press

Caley Ocean Systems designed and manufactured the industry’s largest ZapLok pipelay press for NOV Tuboscope.

The press can handle a range of pipes with a 16” diameter, and features Caley’s proven friction camp technology to create a quick and efficient weldless joint for rapid pipelay operations. The
mechanical connection between carbon steel pipes eliminates quality issues which arise from traditional welding operations, and the costly need for weld inspection. Caley’s system ensures a
faster, safer and more cost effective pipelay.

Caley’s friction clamp pushes together the pre-formed pipe’s bell-end and pin-end. The hardened steel pads hold the pipe in position while epoxy resin is added. The entire connection process takes less than five minutes. In addition to handling the largest pipes, Caley’s Zap-Lok press can handle pipes made from the highest grade steel, and with the largest wall thickness.

“The Zap-Lok is a highly cost effective way to deploy pipelines offshore, especially for marginal fields in shallow water. Using Caley’s Zap-Lok press, we’ve just made the case for Zap-Lok even more compelling.” –Dr Ben Chapman, Director Eastern Hemisphere, NOVTuboscope
