BI-STOP - Small Diameter Line Stop

The patented BI-STOP™ solution provides a unique line stopping 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.
