Bolt Tensioning

Precise Bolt Tensioning Systems for Critical Connections

Torque wrenches rely on friction to generate clamp load, which introduces variability that can affect seal integrity on critical connections. HTC supplies hydraulic bolt tensioning systems from Durapac and ITH, stretching the fastener directly for consistent, accurate preload without friction. The range spans single-cylinder, twin, and segment-type cylinders for simultaneous multi-point tightening across pressure flanges, ring connections, and heat exchangers.
