Stud Tensioner - SFI Orbimax

Zip Tensioner Stud Tensioner

Fastorq’s Zip Tensioners directly load bolts with stud tensioners to provide uniform bolt load.

This ensures leak-free bolted joints which are critical in the subsea, nuclear, and wind industries. Also ideal for offshore, petrochemical, steel and mining.

Zip Tensioners directly load bolts in much less time that it takes to torque bolts and are more accurate than hydraulic torque wrenches.

The ZipTENSIONER is the only diverless tensioner on the market. Others make this claim with tensioners utilizing split nuts that must be manipulated by the ROV. This is very difficult if not impossible. The ZipTENSIONER simply slides on and off the bolt making installation and removal with an ROV possible in a single integrated unit. The ZipTENSIONER is also a huge time saver for nuclear applications and other limited exposure environments.

  • Incorporates the ZipNut® Double Zip® technology.
  • The ZipNut® Double Zip® spring loaded thread segments allow the tensioner to slide over the protruding stud threads, eliminating the time consuming task of threading the puller nut.
  • Can be used for all standard tensioning operations.
  • Compact design allows 100% stud coverage from one side of any ANSI or API flange. For example, the body diameter of a 1 5/8” Stud Tensioner is only 3.538” (90mm) thus improving the ability to fit non-standard applications.
  • Allows for one piece installation.
  • Can be fitted with special hydraulic release mechanism and hydraulic motor driven nut rotator for subsea applications – ROV and diver compatible.
  • Ideal for multi-stud tensioning systems.
  • All parts are stainless steel, nickelplated or coated to provide corrosion protection.
  • Automatic retraction available with specially equipped Power Unit Model HTP-2000
  • Lightweight compared to competitor models.
  • Fully automated single unit slides on and off bolt
  • Cuts tensioning time up to 90%
  • Fastest tensioning available
  • 100% same side flange coverage
  • Compact & lightweight
