Hydraulic bolt tensioner CTP-C series

single-stage

The CTP-C series is the compact line of the FPT hydraulic bolt tensioners and it is characterised by its threaded piston. This construction makes it possible to reduce the clearance and it is the perfect solution to be used on tight environments, when there is no space. FPT makes this type of hydraulic tensioners for all instances when it manages to meet the clearance requirements without needing to move to the technical solution of a multi-stage tensioner. FPT is specialised on design the hydraulic bolt tensioners on the customer specification based on the specific requirements. The compact hydraulic bolt tensioners are built with the threaded piston, this constructive execution allows to reduce the overall dimensions to the minimum allowing to have a tensioner with extremely reduced dimensions and to be able to operate where other tensioners could not be installed. FPT produces this type of tensioner, with threaded piston, in all those cases in which it is possible to satisfy the requirements of space without having to pass to the technical solution of the multistage tensioner. FPT produces compact hydraulic bolt tensioners also in the spring return version to speed up the return operations of the piston. We start from the preliminary study of the existing dimensions and arrive at the definition of the most suitable solution. Tensioners are used instead of hydraulic wrenches and are used for controlled tightening of nuts on stud bolts in the assembly of marine engines, large valves, compressors, pumps, presses, large machine tools and turbines.
