BoltEx® - Bolt Exchange Flange Clamp
BoltEx® ensures flange integrity during the bolt replacement under pressure, also known as 'hot bolting'.
Proven to perform at 1.5 times the design pressure even with all flange bolts removed - BoltEx® presents a robust and effective solution for ensuring bolted joint integrity.

Quick and safe to install
+ 1-2 installers
+ Available at short notice
+ No damage or disturbance to gasket
+ Optimised design and weight for efficient installation and handling
Robust and versatile
+ Proven to perform at 1.5 times the design pressure with all flange bolts removed
+ Countersunk bolts for space restricted locations (e.g., near valves or bulkheads)
+ Open design allows better access to the bolt removing tools (e.g., nut splitters)
+ Designed to be reusable multiple times
+ Can be left in place for an extended period of time preserving flange integrity
Cost effective
+ Eliminates the need for plant shutdown to rectify flange anomalies
+ Prevents loss of containment on flanges
+ 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; compression load on the gasket is maintained as the flange bolts are replaced
+ In case of flange bolt failure BoltEx® safely takes the load preserving joint integrity
