CTST

The CTST series of tools from Ace Tech Tools is a powerful and compact range of multi-purpose bolt tensioning tools. The tools are designed to suit most ANSI B16.5, ANSI B16.47 Series 1, MSS-SP44, API-6A and API-17D flanges and feature well proven and highly reliable hydraulic seal technology.

Multi-Stud Tensioning System

The Segmented Multi Stud Tensioning System (MSTS) is a portable system designed to simultaneously tension all studs on system closures such as steam generator primary and secondary manways, handwheel and valve covers. This state-of-the-art system applies a predictable and accurate preload to all studs simultaneously, thus eliminating the problems normally associated with conventional torque tightening techniques, for example: uneven gasket preloads resulting in closure leakage, galling, broken fasteners, etc.
The MSTS enables the installation and removal of system closures to be completed rapidly in high radiation areas. Therefore, its application is also consistent with meeting ALARA objectives.

Multi-Stud Tensioning System Features
  • Profile cut body to reduce weight
  • Elliptical shaped piston/rams (if necessary)
  • Rare earth magnets embedded in Nut Rotating Sockets, for ease of assembly
  • Single hydraulic inlet connection per segment
  • Can be designed with variable bolt chambers per segment to optimize weight
  • Extremely reliable machine cut polyurethane seals
Hydraulic Nuts

Ace Tech Tools Nuts replace existing hexagon nuts to give a rapid, accurate and uniform Bolt load to any bolted joint. The Ace Tech Tools Nut offers a method of bolt tensioning multi-bolt applications which greatly improves the integrity of the joint. The speed in which joints can be tensioned and detensioned shows an extraordinary time saving over conventional detachable bolt tensioning systems.

  • For temperatures above this level special seals are available, contact Ace Tech Tools for further details
  • The use of machine cut Polyurethane seal, ensure a reliable leak free Tensioning system
