3PE anticorrosion pipe market advantages and problems in Cangzhou

Early 1980s, Cangzhou 3PE anti-corrosion steel is widely used in Europe first, 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 libraries 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 investigate job 3PE coating 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. 1996 Italy Sauk Sam Liu Chang plastics joint venture company with Harbin Construction Shuozhou preservative plant was transformed into 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, especially as Cangzhou steel pipe behalf of the project, so far, 20000KM use external corrosion of buried steel pipe 3PE anti-corrosion coating. Currently there are dozens of 3PE coating operation line, with the processing ¦25-2800mm 3PE steel pipe coating capacity. Increase the degree of market trading coal: coal 2014 annual negotiations, trading institutions and China Coal Transportation and Marketing Association to reach a common consensus that electronic business platform by means of promoting the electricity supplier transactions, reduce losses and increase circulation link, to achieve coal producers to consumer business no intermediate links direct supply. Coal circulation of relevant laws and regulations are constantly improving, support the transformation of coal transactions to electricity suppliers. Continuous improvement of rail capacity for coal circulation development has provided a guarantee. Coal trading center taking shape: coal trading center as much as possible trying to integrate trade and services, in order to continue to seek innovation and development. "1 + N" service, "1" refers to the e-commerce platform as a tool of coal electronic trading this core business, while "N" refers to the wide range of services related to electronic trading of coal, such as clearing, settlement, financial, logistics, Central Purchasing, information and quality assurance business. Electronic business platform to provide informational services to address the problem of information asymmetry opaque and reduce the cost of the middle part of the industry. Electronic business platform through brokered deal, special transaction, etc., can simplify transaction processes, improve transaction efficiency. Enterprises in the industry including manufacturers, distribution business, the demand side, including only need to face the coal business platform, enabling changes in trade patterns, to reduce intermediate links, improve efficiency. The main problem is that coal electricity supplier low commodity degree of standardization, market resource integration capability is weak; difficult to implement electronic transactions, trading patterns still the traditional transaction based; trading system needs to be improved. 3PE anti-corrosion steel base material making do embalmed before checking into the need to enter the steel tube platform, recorded on the outer surface of the steel pipe shot blasting, and then check the cleanliness and anchor profile of the outer surface of the steel pipe to meet the requirements, does not meet the requirements of a qualified repair hand grinding wheel, wrapped in duct tape end paper, dust treatment, frequency heating to the desired temperature, epoxy powder coating, adhesive side winding extruder, PE extruder side wrapped around burning, anti-corrosion pipe water cooling, spray identify qualified products, the down tube platform, stacker to be shipped.
