The Investigation of AW-01 Internal Coating for Natural Gas Pipeline

摘要

Internal coating applied on natural gas pipeline not only can prevent the pipelines from internal corrosion, but also can greatly decrease the roughness of internal surface of the pipeline so that the gas flowing resistance would be reduced and the gas transmission efficiency could be improved largely. In order to meet with the requirement of western gas pipeline projects, a internal coating material special for reducing transmission resistance of gas pipeline has been developed by my Institute. A stimulating test equipment show that transmission efficiency of pipe with special internal coating can be 15.3% more than that of steel pipe without coating.
