Hydraulic Bolt Tensioners


OrbitX make Bolt Tensioners are used for swift method of tightening & opening by tensioning bolt /studs. After apply the oil pressure by OrbitX Hydraulics Pump, Load cell lift the puller up side i.e. tightly gripped with stud bolt thread. This cause release of nut and it becomes loosen. Nut can be easily rotated with nut rotating socket and tommy bar and tightening completed the same process is used for swift loosening operating it mainly consists of Load Cell, puller, Nut Rotating Sockets & Bridge.

Bolt tensioning is now the preferred method of tightening bolts and studs on all critical applications. Bolt tensioners are designed for operation in a wide variety of applications including pipeline flanges, heat exchangers, pressure vessels, compressor covers, boiler feed pumps, windmills and many others. We provide a comprehensive range of bolt tensioners for optimum solutions to bolt tensioning requirements. Our Bolt tensioners and accessories are CE marked in accordance with Pressure Equipment and Machinery Directives, as applicable. In comparison to traditional tightening methods, tightening with bolt tensioners offers significant advantages:
