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