A few days ago, Anyuan pipeline gas-carrying hole plugging technology has been successfully applied in gas projects in Pingxiang City, Jiangxi Province and Xianning City, Hubei Province. This indicates that the “bottleneck” that has long plagued the development of steel-framed plastic composite pipes in the gas market has been successful. To break and fill a technological gap in the domestic pipeline industry.

Anyuan Pipeline Industry Co., Ltd. (Anyuan Pipeline) is a modern pipeline manufacturing enterprise jointly established by Anyuan Industry Co., Ltd. and Harbin Institute of Technology Xinghe Industry Co., Ltd. It is currently the only manufacturer in China that can produce large-diameter steel frame plastic composite pipes . In order to solve the technical problem of plugging the open hole with air in the steel frame plastic composite pipe, and make the replacement, maintenance, emergency repair, emergency rescue and fault handling of the pipe more convenient, the engineers and technicians of Anyuan Pipeline Industry Co., Ltd. aimed at the steel frame plastic composite pipe. The problem of the synthesis of various materials, and at the same time prevent the sparks generated during the sealing process of the gas and pressure openings and cause gas explosions and other technical problems.

After more than a year of in-depth research from drill bit cutters with holes to plugging equipment with air openings, the researchers finally made a breakthrough in technology and successfully applied this independent innovation technology to field trials. They have applied for a national patent. It makes the opening and repair of the steel frame plastic composite pipe more convenient, reliable and safer under the condition of non-stop transmission. The long-term problem of the steel frame plastic composite pipe in the application of gas transportation has been completely solved, and it has a leading position in the same industry in the country.
