SRT: Top Side Tensioner

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

WIND TENSIONERS Our tensioners have quality designed in with standard features that enhance durability and efficiency to get the job done faster and safer: Quality Means Lower Life-Cycle Costs: Achieves 90% proof load requirement for ISO 898 Grade 10.9 bolts Fully enclosed load cell eliminates debris in piston retraction mechanism Auto-Engaging Geared Nut Rotator Self-energizing, long life seals Enhanced Usability: Piston stroke limit indication High pressure swivel coupling (swivel is optional on WSS & WSL) 19,580 psi (1,350 bar maximum operating pressure) Automatic piston retraction mechanism Designed with Safety in Mind: Overstroke prevention for safe operation Anti-slip grip surface Tool lifting-strap as standard WSS & WSL FOUNDATION WIND TENSIONERS Suitable for ISO Metric threaded and all-thread bars Geared or Manual Nut Rotator Long & short stroke models Maximum operating pressure 19,580 psi (1350 bar) Uses standard system 'nut' for reaction Contact factor for op
