Multi-stage hydraulic tensioners Series CTP-M

The multistage hydraulic bolt tensioners, CTP-M series, are characterized by having a central tie rod on which two load cells act, this construction type allows to double the load capacity while maintaining the outer diameter of the cell identical. The result obtained is extremely compact with the same load supplied. The FPT multistage tensioners are suitable for all applications in which there are reduced radial dimensions available. This type of tensioner is also available in the version with a gear nut rotation mechanism to accelerate tensioning operations for fast operation, when time is a key factor. Furthermore, there is the possibility of shaping the bridge so as to best adapt to the space available between the nut and the nut.

FPT realizes multistage hydraulic bolt tensioners to customer specifications by carrying out a preliminary study of the existing dimensions and thus offering 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. I 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.

  • The CTP-M series is the line of hydraulic bolt tensioners characterised by a central puller with two loading cells operate on, this construction makes it possible to double the load capacity whilst keeping the external cell dimension the same.
  • The results obtained are very tight clearances with the load supplied remaining equal.
    • this type of bolt tensioners are suitable for all uses where radial width is restricted.
    • hydraulic tensioners are also available in the version with gear nut rotation mechanism to speed up the tensioning operations.
    • bridge can be moulded in order to best adapt it to the space available between each nut.
