The Jindal SAW JSAW-Lock is a semi-flexible jointing system that provides restraint against axial movements with locking segments placed around the pipe spigot. The pipe socket and weld bead restrain the lock, while a wrapping belt tightens it. JSAW-Lock is used for ductile iron cement-lined pipes manufactured to ISO 2531.
Quick and easy to assemble, JSAW-Lock is suited to trenchless laying, steep slopes, seismic zones, fault crossings, and floating pipelines. It also provides a robust pipe system for high-pressure applications, mine dewatering, bridge pipelines, and water applications without thrust blocks.
Self-restraining design helps transfer thrust forces along the entire system, which removes the need for thrust block. This system can sustain high pressures up to 100 bar and withstand pressure surges.
