Application of the guar gum insulation technology to offshore oil pipelines

During the repair of offshore oil pipeline, in order to mitigate ocean environment pollution caused by crude oil leakage, and guarantee the safety of repairs, the guar gum insulation technology is developed and applied to insulate and purge the crude oil. Theoretical calculation, analysis and experiment show that this technology is feasible and was successfully used in the repair of Pinghu offshore oil pipelines.
