| Objectives | Develop and qualify a Grouted Tee that is suitable for sealant line intervention work. Develop and qualify a compression fitting epoxy encapsulation sleeve. The Grouted Tee passes the required qualification tests The Grouted Tee seal passes the life assessment tests The epoxy encapsulation sleeve passes the required qualification tests Approval of new NG procedure for sealant line intervention work | |
| Abstract | There is no current safe and effective repair method for under pressure repairs to sealant lines. Over the years valve sealant lines that leak gas have been squeezed off to isolate the leak path. This process prevents further leakage but also prevents any further valve sealant from being injected. Consequently, there are now a large number of valves in service that are passing gas with no means to inject sealant. The only present solution is to replace the entire valve which is extremely costly. A proposed solution is to develop a small Grouted Tee connection that will be attached to the sealant pipework, below the squeezed off location. The tee connection will allow hot tap access into the pipework to isolate the leak path and enable the remaining pipework to be modified or replaced. In addition this project will also provide an encapsulation solution to the sealant line compression fittings that are susceptible to leakage.Note : Project Documents may be available via the ENA Smarter Networks Portal using the Website link above | |
