Stretching Tools: ITH-Stretch-Method

ITH Multi-stage Bolt Tensioning Cylinder Type MSK, 10.9

ITH Single-stage Bolt Tensioning Cylinder Type ES, 10.9

The ITH-Stretch-Method is capable of highly accurate, repea-table results to a tight tolerance of ±2.5%. These results are possible because the ITH-Stretch-Method is free of frictional and torsional variables associated with the less accurate torque method. The ITH-Stretch-Method has been established as the preferred bolting process for many industrial applications.

The technical and economical advantages of the ITH-Stretch-Method are attested by the long-standing partnerships bet-ween ITH and other industry leaders. These partnerships span many industries including energy generation (power-turbines, power-plant construction, wind energy), oil & gas industries, gas/diesel engines, heavy machinery and general construction.

Application: Radially limited spaces

Application: Axially limited spaces
