BI-STOP Small-bore line plugging

Our 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.
