STS - IMPERIAL TOPSIDE STUD BOLT TENSIONERS
|
- Capacities from 234 to 2649 kN
- Working pressure 1500 Bar
- Single acting design
|
The STS stud bolt tensioner range is designed for topside operation in a wide variety of applications including pipeline flanges, heat exchangers, pressure vessels, compressor covers, boiler feed pumps, anchor bolts and many others. The range comprises of 23 imperial and 29 metric models, all suitable for working pressures up to 1500 Bar. Imperial models cover all standard bolt sizes from %" to 4", metric versions (detailed on page 93) are available for bolt sizes from M16 to M100. Each of the hydraulic cylinders can be used with a variety of interchangeable nut rotating sockets and threaded pullers, available as individual parts or as convenient conversion kits (see pages 94 and 95 for more specific details). This will ensure that the maximum number of bolt diameters can be accommodated using the minimum number of cylinders. All Hi-Force hydraulic stud bolt tensioners are designed and manufactured to include a wear coated piston, maximum piston stroke indicator, self-energising high pressure seals, dual quick connect couplings for easy multiple tensioner connection and a user friendly operation and maintenance procedure. Additional or spare bridges, threaded pullers and nut rotating sockets can be supplied as and when required. Suitable manual and air driven hydraulic pumps, high pressure hoses and couplings for use with Hi-Force stud bolt tensioners are detailed on pages 97 & 98.
