The SRJ BoltEx is intended to facilitate safe flange bolt replacement during normal operations also known as “hot bolt” capability. Boltex can also give assurance in cases of degraded flange connections by providing flange reinforcement for extended periods. BoltEx is a safe and cost-effective solution to ensure flange joint integrity in the event of damage or during bolt replacement.
lightweight design aids installation; smart design allows assembly in both horizontal and vertical applications; smaller flange sizes only require 1-2 installers; simple design ensures safe and fast installation; back-stop prevents over compression of flange gasket.
Robust Design – design validated using finite element analysis and extensive testing; can take the full loading of the flange even with the flange bolts removed – ASME PCC-1; enables prolonged application until system shutdown is possible; enables bolts to be replaced with new.
Compact & Reusable – Applicable to restricted locations and enables space efficient storage and transportation; designed for fast and efficient installation and handling; easy to remove and reinstall multiple times.
1. Immediate Intervention
Corroded bolts can be replaced immediately after BoltEx is installed (in accordance with ASME PCC-2 Hot Bolting)
2. Extended Flange Lifetime
BoltEx can be left installed as a preventative measure on the flanges with heavily corroded bolts that are impossible to retrieve/replace. In the case of the bolt failure BoltEx will safely take the load preserving joint integrity.
3. Asset Monitoring
Optional integrated sensors will enble remote/continuous asset condition monitoring, providing the operator with additional level of safety and certainty in the joint integrity
