FPT – Fluid Power Technology designs and manufactures standard and custom made hydraulic bolt tensioners from 700 to 2500 bar. The TTS series is the standard range and is designed to adapt to the main types of flanges: ANSI B16.5 – ANSI B16.47 – B.S.3293 – AWWA – MSS-SP44 – API-6A – API-17D – UNI EN 1092-1. It has high forces and very reduced dimensions. It gives the user maximum flexibility since with the 6 hydraulic cells the operator can cover a wide range of imperial and metric threads from 3/4 ”to 4” and from M20 to M100.
The reference markets increasingly require custom hydraulic tensioners made to customer specifications in order to be able to operate in the required dimensions and with the characteristics suitable for individual needs. The special tensioners can be compact, multi-stage, with threaded insert and with spring return. The CTP series with threaded insert is characterized by having the interchangeable threaded bush which allows to operate on tie rods with different threads with a single hydraulic cell. The CTP-M series are characterized by having a central tie-rod on which two load cells act, this type of construction 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 CTP-C series is the compact version with threaded piston. This constructive typology allows to reduce the overall dimensions allowing to operate in environments with reduced spaces.
FPT follows the customer from the study of the geometries to the 3D project up to the production of the required tensioners. FPT also produces all the products that make up the hydraulic circuit, including both electric and air control units, hand pumps and all the components suitable for operating the system. It carries out technical training courses and on-site training to provide operators with all the tools necessary for the correct and safe use of FPT hydraulic equipment
