The cold-wrapped tape is based on summarizing the accumulated experience of epoxy coal pitch anti-corrosion coatings that are widely used in China. In view of the problems existing in the use of this coating for external anti-corrosion of steel pipes, the cold-wrapped tape is carried out to keep pace with the times. A new type of pipeline external anti-corrosion material developed through continuous improvement. According to experts from the China Epoxy Resin Industry Association, the epoxy coal pitch coating used for the anti-corrosion of buried steel pipelines was arranged by the former Ministry of Fuel and Chemical Industry in 2011. The former Northeast Engineering Survey and Design Institute is now divided into PetroChina Pipeline Engineering Company and Pipeline Science Research Institute. In 2008, the Ministry of Petroleum issued the "Technical Standards for Epoxy Coal Asphalt Anticorrosive Layer for Buried Steel Pipelines" and the "Epoxy Coal Asphalt Anticorrosive Layer for Buried Steel Pipelines" It has been a year since the standard was merged and revised into the "Technical Standard for Epoxy Coal Asphalt Anticorrosion Layer of Buried Steel Pipelines" in 2008, which was the Chinese oil and gas industry standard.
