STU - Sub-sea bolt tensioners - Metric Range

Brand: Hi-Force  

Hi-Force STU metric series sub-sea bolt tensioners are produced to fit into the demanding needs of divers operating in ruthless sub-sea locations. These tensioners are simple to use two-piece design which consists of a quick fit/release threaded puller and a hydraulic load cell with primary bridge and an additional long 30mm piston stroke to reduce re-setting operations. Hi-Force sub-sea bolt tensioners provide a dependable, reliable and reasonable cost process of tensioning sub-sea bolted joints. All hydraulic load cells are suitable for different thread sizes and are interchangeable, see table below. Quick fit/release pullers can be ordered separately, as required, resulting in even greater flexibility and cost savings.

Features

  • Working pressure 1500 Bar

  • Interchangeable quickfit/release pullers
  • Load cell with integral bridge
  • Dual hose connection for easy hook up
  • Extra long 30mm piston stroke to reduce re-setting time
  • Maximum piston stroke indicator
  • Corrosion protected for operation in harsh sub-sea environments
