ITH Multi-Tensioning for the ANSI-flanges

Tightening ANSI-flange bolt connections: It is recommended to tighten several bolts at the same time to significantly reduce the risk of leakage.

ITH Multi-Tensioning
By using the ITH-Multi Tensioning method, multiple bolt tensioning cylinders are used simultaneously by connecting them to one hydraulic unit (connected in series or in parallel). All bolts are tightened simultaneously and the required pretensioning forces are generated evenly. This leads to precise results: Using ITH-Multi Tensioning repeatable pre-tensioning force within a tolerance level of ±2% can be reached.

Advantages tightening bolts with the ITH Multi-Tensioning:
Using the ITH Multi-Tensioning method leads to:

  • Significantly reduced risk of leakage
  • Increased lifetime of flanges, seals, and fasteners
  • Fast working procedures
  • Reduced downtimes of the complete application which saves costs
