Bolt tensioners

1. Spring return bolt tensioner – metric – SBT

Single acting design with spring assisted piston retraction. High grade alloy steel construction with nitrocarburised, corrosion resistant, piston. Maximum stroke indicator to warn against piston over extension. Safety over stroke device to protect operator from injury and longevity at high pressure. Dual quick connect inlet and outlet couplings for easy multiple tensioner connection. Designed to […]

Capacities from 457 to 2649 kNMaximum working pressure 1500 barBolt sizes from M30 to M100 diameter

2. Topside bolt tensioner – metric – STS

Single acting design with manual piston retraction. High grade alloy steel construction with nitrocarburised, corrosion resistant, piston. Maximum stroke indicator to warn against piston over extension and longevity of use at high pressure. Dual quick connect inlet and outlet couplers for easy multiple tensioner connection. Designed to fit most sizes of ANSI and API flanges […]

Capacities from 234 to 2649 kNWorking pressure 1500 barBolt sizes from M16 to M100 diameter

3. Sub-sea bolt tensioner – metric – STU

Single acting design with manual piston retraction. Manufactured from high grade alloy steel with added corrosion protection.
