Hydraulic tensioners with threaded insert Series CTP

The hydraulic bolt tensioners with threaded insert are characterized by having an interchangeable threaded bush which allows to operate on tie rods with different threads with a single hydraulic cell. This configuration is extremely versatile in all cases where tensioning rods with different threads and similar dimensions must be tensioned, it will only be necessary to have sets of bushes, different polygonal keys and in some cases the bridges.

FPT – Fluid Power Technology manufactures hydraulic bolt tensioners with threaded insert according to customer specifications, carrying on a preliminary study of the existing dimensions and thus offering the most suitable solution. Tensioners are used instead of hydraulic torque wrenches and are used for controlled tightening of nuts on stud bolts in the assembly of marine engines, large ball valves, compressors, pumps, presses, big machine tools and turbines. They can be designed to adapt to the main types of flanges: ANSI B16.5 – ANSI B16.47 – BS3293 – AWWA – MSS-SP44 – API-6A – API-17D – UNI EN 1092-1, including Norsok flanges, Vector, Slip on, Weld Neck and many others.
