HYDRAULIC CYLINDERS AND TORQUE WRENCHES
The expansion bolts on turbine housings, flanges and rotor couplings are mounted with a prestress in the range of elasticity. To achieve this, GE and other global OEMs use special hydraulic screw tightening tools for cold elongation applications. Such equipment is mainly supplied with OEM turbines for maintenance purposes.
We are able to offer you high quality German hydraulic cylinders and torque wrench for all types of OEM turbines as well as the possibility of custom made production of these tools with complete engineering.
