We hope that through our efforts, with your support, let us together to write a better tomorrow Rendezvous. First 3PE anti-corrosion steel is widely used in Europe, praised by users, it is the most used line coating system. China National Petroleum Corporation in the summer of 1994 decided to introduce 3PE coating operation and coating techniques, for the upcoming start of the Shaanxi-Beijing gas pipeline and Ku-Shan pipeline external corrosion coating. In December, the Central Bureau of oil infrastructure, Pipeline Bureau, Sichuan Petroleum Institute, the headquarters of Northwest Pipeline joint delegation of experts to the United States, Italy, Turkey and other countries to study 3PE coating operation line. May 1995, the Liaohe oil company responsible for the construction of a tender from the Canadian Labour root of the first companies to introduce a line of 3PE coating operation. In early 1996 put into normal production. In 1996 the Italian company Sauk Sam Liu Chang joint venture with Harbin plastic Shuozhou preserving plant actually transform normal production in May. Northwest Pipeline joint venture with Hong Kong headquarters from the Netherlands to introduce 3PE coating operation line, in 1996 in Baoji Yadong preservative company put into operation so far, 3PE anticorrosion get attention and application in China. Starting from Shibuya ninglam pipeline construction, through the tender, plus all domestic 3PE anti-corrosion materials, 3PE anticorrosion prefabricated prices dropped significantly, from the beginning of the era of domestic 3PE preservative widely used, so far 20000KM external corrosion of buried steel pipe 3PE preservative use coating. Currently there are hundreds of 3PE coating operation line, with the processing Φ25-2800mm 3PE steel pipe coating capacity. 2PE / 3PE anticorrosion pipe which is suitable for coal mine drainage, underground shotcrete, positive and negative pressure ventilation, gas drainage, fire sprinkler pipe network. Waste heat and power plant process water, backwater pipeline. For the anti-spray, water sprinkler system piping has excellent applicability. Electricity, telecommunications, highways and other cable protection sleeve. Suitable for high-rise building water supply, heat supply network, water works, gas transportation, underground water and other pipelines. Oil pipelines, chemical industry, printing and dyeing industry, transport process piping of corrosive media. Sewage discharge pipes, sewers and biological corrosion engineering pool. Agricultural irrigation pipes, deep well pipes, drains and other network use, etc., it can be said 3PE anti-corrosion steel in the current building is essential, and I believe that through the extension of technology, the future of which is still more brilliant achievements. Standard specification mainly polyethylene and high density polyethylene-based, as Vicat softening point of not less than 110 ℃; thickness of the outer coating of the press to a low, medium density polyethylene-based German standards DIN30670-1991 determined greatly improve the impact strength of 3PE coating.
