Hydraulic bolt tensioning is the most consistent of applying accurate pre-load to bolts. Bolt tensioning is an accurate and time saving method for tightening bolts and studs in all industries. Controlled bolt tensioning to calculated values to eliminate flange leakage. Versatile compact design ensure maximum economy over any given size range.

Subsea Bolt Tensioning

The bolt tensioners are designed for quick and accurate tensioning of pipe flanges etc. in a subsea environment. The tensioner has a minimum of parts to enable fast and simple attachment to studs where visibility is poor. Quick fastening reaction nut: allows rapid tool application and removal regardless of bolt length, corrosion or thread damage. Unique floating piston design: tilts in any direction without loss of load, eliminating piston seizure and aiding tool retraction. The Subsea tools are safe and easy to use.
