SEAStallion ™ Subsea Bolt Tensioners

There is no environment in the world that is more hostile and dangerous than working subsea, on offshore platforms. Absolute zero- defects solutions are essential to protect the environment and ensure uninterrupted production. SEAStallion™ Sub-sea Hydraulic Bolt Tensioners were developed to meet the challenge of preventing leaks - since any leak could result in catastrophe.

Control is everything in undersea work. Specifications must be met in absolute terms. Tools must be designed so they may be used safely and effectively in a watery and murky environment. Time is of the essence, and SEAStallion's simultaneous, multi-stud tensioning, can save up to 80% of the time needed by alternative methods, in the simultaneous bolting of multi-stud sealed joints.

SEAStallion™ Sub-sea Hydraulic Bolt Tensioners provide the fast, high load, controlled power required to align, pull up and reliably seal; pipeline flanges, clamped joints, repair clamps, templates and other critical sealed connections.

Because of their exacting precision and safety margin SEAStallion™ Sub-sea Hydraulic Tensioning tools have been used in almost every North Sea subsea pipeline - and have since proven themselves widely in the Gulf of Mexico and the eastern seaboard.

• Scalloped Split Reaction Nut

  • The unique SEAStallion™ split reaction nut is scalloped for better grip and confident handling – ideal for damaged nuts

• Extended Piston Stroke

  • 30mm piston stroke on the SS2 through SS7 allows for tensioning on numerous flanges without retracting the ram

• Piston Over Stroke Prevention

  • A stroke indicator on the ram allows for use of maximum stroke without over stroking the ram or losing oil pressure

• Compact Design and Tool Range

  • Not only is the SEAStallion™ small and light you only need 7 tools to cover a full range of flange sizes

• Simple Hose Connections

  • Duel ports eliminate the need for a tee block

• Higher Bolt Loads are now possible

  • Maximum operating pressure 21,750 psi

• Corrosion Resistance

  • Stainless steel components
