Small-Bore Hot Tapping and Plugging

The patented BI-STOP™ provides a unique hot tap and plugging system to address 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 whilst the system remains live. The 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
