Top side bolt tensioners

Series TTS

Top side bolt tensioners


The Tensioners TTS Series are designed to suit most flanges type: ANSI B16.5 – ANSI B16.47 – B.S.3293 – AWWA – MSS-SP44 – API-6A – API-17D – UNI EN 1092-1

Powerful and extra compact. Great ratio between developed force and tools dimensions.

Dimensions and weight make the difference. TTS Series is extremely compact and light weight to be suitable for the most tensioning operations.

Maximum flexibility. With only 6 hydraulic cells the operator can cover an extended range of Imperial or Metric thread sizes from 3/4” to 4” and from M20 to M100.

15 mm stroke cover most of the tensioning application. If longer stoke are required the tensioning operation can be carry on by steps. TTS1 has 10 mm stroke.

Safety is a must. All size have the Anti Over Stroke Mechanisme. 

All model are equipped with 2 quick couplers male and female for serial hydraulic connection between tensioners.

Custom made Hydraulic Bolt Tensioners to fit to Norsok flanges, Vector Flanges, Slip on flanges, Weld Neck flanges and many others.

Top side bolt tensioners

The TTS series is the standard range of top side bolt tensioners designed and produced by FPT – Fluid Power Technology. It is 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. It is characterized by high forces and reduced dimensions, in fact it has the optimal combination between the developed force and the extremely small dimensions.

The extremely compact dimensions and low weight make this range the most versatile available, suitable for applications where installation spaces are reduced to a minimum. Furthermore the light weight facilitates the maneuvers.

The range consists of 6 hydraulic load cells that the operator can combine with a wide range of kits both for imperial and metric threads, thus obtaining a total coverage from 3/4 „to 4“ and from M20 to M100. For maximum flexibility.

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 custom made top side bolt 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 hand 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.

  • Safety is a must. All size have over stroke indicators
  • Custom made Hydraulic Bolt Tensioners to fit to Norsok flanges, Vector Flanges, Slip on flanges, Weld Neck flanges and many others.
  • Special high quality seals for leak free operations and easy maintenance
