Since there is only a requirement for one excavation instead of the traditional fi ve excavations associated with replacing a large diameter valves using Line stopping and Bypass the cost savings are immediately apparent LINE STOPPING At PTS our globally earned reputation in this area mean we provide one of the most diverse and technically competent offerings in the business, including our unique and patented 'POWERSTOP' (copyright logo) process. PTS are able to control the cease fl ow in pipelines from DN80 to DN1500 in multiple media in Oil and Gas to Water at pressured to 150 bar. • Suitable for polyethylene, PVC, steel, ductile, cast and other rigid pipes • Easy installation, only a torque wrench is required • Easy to fi t even on out of round pipes • Very high pull-out pressure rating • Patent pending dynamic gripping features. Each gripper is independently torqued to provide heavy-duty performance as well as tolerance and perfect fi t on any pipe surface. In addition, the grippers have a wedged- shaped sliding section that dynamically increases the gripping force as the pipe tends to pull out • Widest tolerance for the connection of pipes of the same or different material with the same or different OD • Compensation of pipe ovalization • Angular compensation of up to 6° before or after installation • Can be assembled and disassembled several times, the grippers are held in place with special locking nuts and do not come off when undone • Flange adaptors can be effectively used as dismantling joints thanks to their long body and large tolerance range Power Restraint Universal large tolerance heavy-duty end-restrained couplings, reducers and fl ange adaptor. Available in diameters from 300 mm to 1400 mm Different diameters or lengths are fabricated on demand Larger sizes available at request Power Restraint Mechanical Couplings, Straight, Stepped, Reducers and Flange Adaptors. Double bolted end restrained mechanical couplings and fl ange adaptors wih 30 mm tolerance on pipe OD and dynamic grippers with the same tolerance as the rubber seals. ADVANCED PIPELINE SOLUTIONS
