One Step polyurethane insulating pipe equipment Product description: This technology is the insulation layer and coating in the pipe at the same time-coated outer surface, thus insulating coating of the pipeline, pioneered by China. Compared with other methods, with continuous operation, high efficiency, low cost, energy conservation, pollution-free environment, as well as advantages, in 1985 the national science and technology progress second prize, several technology update to the advanced international level. The new "one-step" process characteristics: A material to be used widely, by the epoxy powder and various anti-corrosion coating on the pipe. 2, the bubble can be high-temperature polyester foam and asphalt black bubble. 3, jacket layer and the layer adhesive foam, foam adhesive layer and coating, adhesive coating and pipe firmly. One-step molding built by the anti-corrosion pipe insulation production line high degree of automation, the quality of insulation coating completely in line with the national standard. 83 since the technology has been successfully developed, the improvement of nearly 20 years of improved operating pipeline currently has a range of φ48 mm φ1000 mm above. Pipe insulation coating mainly used for crude oil pipeline, buried heating and cooling system pipe insulation pipeline corrosion, very broad application prospects, a high rate of return on investment. Can be used in central heating units, long-distance transportation, water supply, gas supply and other projects. Pipe insulation foam jacket forming anti-corrosion technology is the early 1980s, the oil from the Organization Department of infrastructure experts to Canada after the inspection, in the country to promote the new oilfield technology and abroad "two-step" on the basis of Process, Shengli Oilfield oil Jian Technology Institute in 1983 launched the first "one-step" molding techniques, namely the preservation pipe insulation foam molding technology and external insulation layer with a jacket shape, we call this "one-step" operations. The success of this technology will not only improve the operating efficiency and significantly save material costs have been reduced to facilitate the construction project, the technology will soon be in the field of promotion, and received the top ten scientific and technological achievements in Shandong Province, in 1985 access to national patents for inventions, up to now, there are no "one-step" technology come out.plastic machinery
