Testing of new Type of Split Sleeve for Pipeline Repairs by Internal Pressure
Journal Title: Mašinstvo - Year 2016, Vol 13, Issue 1
Abstract
Repairing technologies for pipelines still require attention due to large extent of distribution network containing different construction parts including elbows, branch connections and others. Repairing of the defects in the branch connection area without interruption of the gas supply is very difficult. Such defects mostly require replacing of the damaged part with interruption of media supply or construction of the bypass around the branch connection. The first method is sometimes difficult to realize and the second is relatively expensive due of necessity of hot-tapping (creating of the hole into the pipeline and welding without the interruption of media supply). In this article, new repairing technology with application of special split sleeve is presented. Computation of required wall thickness is described together with testing based on internal pressure.
