Key Characteristics
- Designed to ASME PCC-2, ASME VIII, and ASME B16.5
- Enables safe bolt replacement during normal operations
- Ensures flange integrity until the next shutdown opportunity
- Validated by FEA to perform at 1.5 times rated line pressure with all flange bolts removed
Industry Challenges
- Corrosion of piping systems
- Flange and weld failures
- Safety risks
- Costly repair works
- Shutdowns – Penalties
- Loss of containment – Loss of production
Our Clients:
BoltEx® – Bolt Exchange Clamp
BoltEx® can be left installed as a preventative measure on defected flanges with bolts that are impossible to retrieve/replace, extending flange lifetime. Corroded bolts can be replaced immediately in accordance with ASME PCC-2 (Hot Bolting).
Key benefits:
Quick and safe to install
- 1-2 installers
- Available at short notice
- Optimised weight for ease of use
- No damage or disturbance to gasket
Compact and reusable
- Countersunk bolts in one side for limited access applications
- Open design allows access to the nut splitter for removing corroded flange bolts
- Designed for fast and efficient installation and handling
- Easy to remove and reinstall multiple times
- Space-efficient storage and transportation
Cost effective
- Eliminates the need for plant shutdown
- Extends asset lifetime and reduces maintenance costs
Innovative Gasket Protection System (GPS)
- GPS prevents over-compression or release of sealing pressure of flange gasket
- BoltEx® bolts are pre-loaded against the GPS with an equal tension to the flange bolts; compression load on the gasket is therefore maintained as the flange bolts are removed
- In the case of bolt failure BoltEx® will safely take the load preserving joint integrity
