Materials and Technologies Ensuring Environmental Safety of Reconstruction and Overhaul of Trunk Pipelines

Abstract

Abstract The paper presents an overview of the studies of Russian and foreign scientists exploring the issues of reliable operation of trunk pipelines transporting oil and gas. It is found that subsea pipeline networks pose a greater danger in terms of their functional failures and environmental effects and appear more prone to stress corrosion cracking. Certain materials and technologies are brought into focus to demonstrate that their use allows curbing the environmental expansion or ensures the reliable operation of oil and gas pipelines. It is noted that one of the most promising methods for reconstruction and overhaul of trunk pipelines provide for the application of composite materials to the internal surface of a damaged pipes. The appropriate formulation of composite materials depends on the condition of the internal pipeline cavity. Also, there are scientific breakthroughs which may serve to reduce corrosion activity of clayey soils. Stress is laid on the importance of innovations in the development of technologies and materials ensuring the maintenance of ecological balance in the areas where oil and gas transmission networks operate.
