Segment Type Hydraulic Bolt Tensioning Cylinder
A modular segment-ring tensioning system for simultaneous tightening of four or more bolts on a ring flange, from M24 upwards, reducing leakage risk.
More Information
The ITH Segment Type hydraulic bolt tensioning cylinder is designed for simultaneous tightening or loosening of a ring flange connection in one operation. Multiple segments connect into a hydraulic circuit and pressurise together, so all bolts on the flange tension in parallel. This even, simultaneous load distribution reduces the risk of leakage at the connection.
How It Works
- Individual segment cylinders are positioned around the flange, matched to the bolt spacing and dimensions.
- Multiple segments connect together into one hydraulic circuit, forming a segment cylinder ring.
- The circuit connects to a hydraulic pump and pressurises all segments simultaneously.
- Parallel tensioning across every bolt connection achieves even, consistent preload.
Key Features
- Simultaneous tensioning of four or more bolted connections in one operation, from M24 upwards.
- Speed mounting concept and weight-optimised design speed up installation.
- Modular design with robust, ergonomic handles for on-site handling.
- ITH safety concept includes a patented cycle counter and patented safety fracture device.
- Opens and closes easily during flange maintenance.
Typical Applications
- Ring flange connections requiring even, simultaneous preload
- Pressure vessel and pipeline maintenance
- Applications where leakage risk must be minimised
- Large-diameter flanges with multiple closely spaced bolts
