The HTR series of bolt tensioners is a new range of spring return hydraulic tensioners optimised for topside applications using the best quality components and surface treatments available. Designed to suit ANSI, ASME and API flanges, the HTR series features a fast spring piston return, making them perfect for tightening multiple bolts in multiple pass operations.

Powerful internal springs reset the tensioner piston, so it is always ready for the next operation. This reduces operator fatigue and increases the speed of tensioning. The tools include important safety features like a maximum stroke indicator and an internal relief valve to prevent accidental piston over-stroke. This eliminates unnecessary downtime spent replacing a seal.

Versatile for all bolting applications
The CE-marked HTR range operates at 1500 bar and comes with a pressure test certificate, as well as detailed operating, maintenance and safety manuals. All HTR tensioners are available from stock and can be configured with single or twin ports accompanied by standard pumps, hoses and fittings.
