Abstract
Abstract
The analysis of scientific literature, technical solutions and inventions in the field of polymer composite materials for temporary gas pipeline compaction is carried out. It was revealed that for sealing the pipeline, polymer compositions based on rigid polyurethane foams, or compositions that swell in the cavity of the gas pipeline with the formation of a gel-like plug, can be used. A mandatory requirement is the ability to remove the sealing plug from the insulated cavity of the gas pipeline after the completion of repair work.
The analysis also showed that there are few studies in the field of creating polymer composite materials for temporary sealing of gas pipelines. The development of compositions that meet all the requirements is of practical interest for the gas industry.
