BI-STOP Line Plugging
Small-Bore Line Plugging
Page last modified
April 11 2024
The patented BI-STOP™ solution provides a unique temporary line plugging system. BI-STOP addresses challenges with small-bore pipework that have absent or limited isolation facilities. This cost-effective solution enables small-bore pipework to be isolated, cut and if required, terminated with a full-bore valve while the system remains live. BI-STOP allows maintenance or remediation activities to be carried out safely and reliably, eliminating the need for a system shutdown.
Applications
- Provide a temporary isolation to facilitate pipework repair or modification
- Install a system specified full-bore valve where isolation facilities are absent or limited
- Cap and terminate dead leg or redundant pipework
- Provide a permanent or temporary pipework tie-in
