Cylinders and pistons - Import export

In addition to standard features normally associated with Segmented Bolt Tensioners, our system also provides the following benefits: Quick Reaction Nut, solid nut or puller sleeve versions Visible piston stroke indication Piston / cylinder mis-alignment compensation Available in Subsea and Topsides versions Designed to fit most flange configurations

SST STUD TENSIONER Quick Reaction Subsea Tensioner Our Subsea stud tensioner incorporating the quick reaction nut feature reduces diver fatigue, improving diver safety and productivity. Visible piston stroke indication Positive ‘over-stroke’ stop to prevent piston expulsion/seal damage. Piston/cylinder misalignment compensation Anti-slip cylinder surface for improved handling Low friction seals Anti-corrosion coating Bolt coverage from 3/4" to 4" (M20 to M100) Designed to fit BS1560/ANSI B16.5/API flanges, as well as most compact flange designs Piston stroke: 30mm except for SST1 - 20mm Max tool pressure: 21,750 psi (1,500 bar) Bolt protrusion above nut: refer to chart (specification) for stud protrusion requirements ‘D’ includes an allowance for tool removal after bolt tightening with 30mm tool stroke Product development is constantly taking place and dimensions may change without notice

MRT MANUAL RETURN BOLT TENSIONER Our economy range of bolt tensioners offer low-cost tensioning solutions. Incorporating our unique quick-release bridge adaptation, a range of adapter kits provide maximum flexibility. Piston stroke limit indication Piston/cylinder misalignment compensation Bolt coverage from 1" to 3-1/2" with just 6 tools Designed to fit BS1560/ANSI B16.5/API flanges Unique quick-release bridge adaptation Application specific tooling available. Contact factory for details. Piston stroke: 15mm (excluding MRT1 - 10mm) Max tool pressure: 21,750 psi (1,500 bar) Bolt protrusion above nut: 1 x bolt diameter ‘D’ includes an allowance for tool removal after bolt tightening with 15mm tool stroke Weight excludes puller sleeve To make a complete MRT Tensioner, choose an Adapter Kit and a Load Cell. Semi-compatible with SRT tensioners. Only compatible with SRT Bridges; NOT puller sleeves. SRT Puller Sleeves cannot be used with MRT Load Cell.

SRT SPRING RETURN BOLT TENSIONER The Spring Return design dramatically increases productivity and safety on the job site when compared to older technology manual return tensioners. Piston overstroke prevention Piston stroke indication Compatible with MRT Tensioner range Unique quick release bridge adaptation Piston/cylinder misalignment compensation Bolt coverage from 3/4" to 4" (20 - 115 mm) with just 8 tools Designed to fit BS1560/ANSI B16.5/API flanges Fully enclosed load cell design eliminates entry of debris into piston retraction mechanism Piston over-stroke eliminator to prevent over stroking and blowing a seal Twin hydraulic couplings for multiple tool connections Requires stud to protrude above nut by 1 x bolt diameter Application specific tooling available. Contact factory for details. 10 mm piston stroke Max tool pressure: 21,750 psi (1,500 bar) Bolt protrusion above nut: 1 x bolt diameter (minimum)
