Hi-Force STU series sub-sea bolt tensioners are designed and manufactured to suit the demanding requirements of divers operating in harsh sub-sea environments. With an easy to operate two piece design comprising of a quick fit/release threaded puller and a hydraulic load cell with integral bridge and an extra long 30 mm piston stroke to reduce re-setting operations, Hi-Force STU series sub-sea bolt tensioners offer a consistent, reliable and cost effective method of tensioning sub-sea bolted joints. All hydraulic load cells are suitable for different thread sizes and interchangeable quick fit/release pullers can be ordered separately, as required, resulting in even greater flexibility and cost savings.

• Capacities from 256 to 2483 kN
• Bolt sizes 1″ to 3½” diameter
• Working pressure 1500 bar
• Single acting design with manual piston retraction
• High grade alloy steel construction
• Simple two piece design for easy operation by divers subsea
• Visible maximum piston stroke indicator
• Dual quick connect couplings for easy connection
• Designed to fit most sizes of ANSI and API flanges and some Compact flanges
• Interchangeable quick fit pullers to cover secondary bolt sizes for each STU model
• Customised and special design tensioners are available on request
