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 […]
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 […]
3. Sub-sea bolt tensioner – metric – STU
Single acting design with manual piston retraction. Manufactured from high grade alloy steel with added corrosion protection. Extra-long piston stroke on all models, to save valuable diver time subsea. Simple two piece design for easy operation by divers subsea. Visible maximum stroke indicator to warn operator against piston over extension. Safety over stroke device to […]
4. Sub-sea bolt tensioner – imperial – STU
Single acting design with mnual piston retraction. Manufactured from high grade alloy steel with added corrosion protection. Extra-long piston stroke on all models, to save valuable diver time subsea. Simple two piece design for easy operation by divers subsea. Visible maximum stroke indicator to warn operator against piston over extension. Safety over stroke device to […]
