Bolts and clamps are precision fastening components used to securely seal and maintain pressure integrity in industrial manholes and cleaning ports.
| Parameter | Typical range | Notes & selection driver |
|---|---|---|
| Bolt Size Range | M8 to M36 | |
| Pressure Rating | Up to 25 bar | |
| Thread Standards | Metric coarse/fine, UNC/UNF | |
| Temperature Range | -40°C to 400°C | |
| Torque Requirements | 20-500 Nm depending on size | |
| Clamp Diameter Range | 100mm to 1000mm |
Ranges are indicative industry figures for RFQ preparation, not a supplier commitment. Confirm every value and standard with the legal manufacturer before ordering.
This component is used in the following industrial products

Manufacturer profiles associated with Bolts/Clamps.
Manufacturer listings support early research and capability understanding. They are not certification, ranking, or transaction guarantees.
Bolts provide individual point fastening through threaded tension, while clamps offer continuous circumferential pressure. Bolts are better for high-pressure applications requiring precise torque control, while clamps allow quicker access and more even pressure distribution.
Initial retorque after 24-48 hours of operation, then quarterly inspections with annual retorquing. Frequency increases with thermal cycling, vibration, or pressure fluctuations.
No - mixing materials can cause galvanic corrosion. Always use matching materials for bolts, clamps, and mating surfaces, or use isolation methods when dissimilar materials are unavoidable.
