Atlas Copco CTST Bolt TensionersAtlas Copco Tensioner Range

The Atlas Copco CTST range of topside bolt tensioning tools consist of 6 base tools covering bolt sizes from 3/4¨ to 4¨ (M20 to M100). The tools are designed to fit on to most ANSI B16.5, ANSI B16.47 Series 1, MSS-SP44, API-6A and API-17D flanges. Each base tool can be converted for use on a different bolt size by the use of a conversion kits.

Benefits

  • Faster – Piston return more than twice as fast as spring assisted tensioners.
  • Lighter – A 20% weight saving versus spring assisted equivalents reduces operator fatigue.
  • Sustainable – Enhanced corrosion protection for harsh environments.
  • Interchangeable – Airbac tools feature the same load output, bridges and NRS as the CTST range.
