Hydraulic tensioners with threaded insert

0,00

The CTP series is a type of hydraulic bolt tensioner characterised by the threaded interchangeable insert which makes it possible to work on studs with various threads, using just one hydraulic cell.

This configuration is extremely versatile whenever stud with different threads and similar clearance must be tensioned, all you need is a set of inserts different sockets and in some cases bridges.

FPT manufacture this type of hydraulic tensioners to the customer’s specifications, carrying out a preliminary study on the existing clearance in order to offer the most suitable solution.

Hydraulic bolt tensioners with threaded insert

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.

All the components are made with high-strength steels and have a special treatment to ensure high resistance to corrosion and high resistance to wear during screwing operations.

FPT is specialized in the study and production of special hydraulic tensioners from 700 to 2500 bar. The reference markets increasingly require hydraulic tensioners made to customer specifications so as to be able to operate in the required dimensions. FPT follows the customer from the study of the geometries to the 3D project up to the production of the required tensioners. It also takes care of following the customer in the development of the hydraulic circuit by supplying the electric or air control units, the lever pumps and all the components suitable for operating the system, with pressures starting from 1600 bar, 2800 bar, 3000 bar. The hydraulic tensioners can be single-acting with spring return, with air return, compact, suitable for the wind sector, with threaded insert, with bridges or special geometries in order to adapt to every single need.

  • Hydraulic bolt tensioners suitable for any type of design
  • Maximum versatility in the composition
