Manufacturers supply from the plastic pipe market demands, pe composite pipe year 2000, PP-R pipe market demand is less than 10,000 tons; in 2001, PP-R pipe market demand of about 3.5 million tons. PP pipes carry hot and cold water industry, its raw materials domestically are required to have a premise. For hot and cold water PP-R pipe market space and carry out ambitious outlook, therefore, domestic Yanshan Petrochemical, Yangzi Petrochemical, Jinshan Petrochemical and other petrochemical companies to proceed with numerous special PP pipe special resin is PP-R pipe resin for discussion and open up. However, the current domestic PP-R pipe materials have not yet been demonstrated time grading hydrostatic strength, still in its infancy. Currently, the domestic plastic pipe has constituted a series, include agricultural pipe, built with hot and cold water pipes and other PP, some companies currently underway to develop special materials buried pipes. But demand noting that throughout the country there is a lack of current data-processing functions tube research, then incur skills serve not perfect, further research and develop the domestic impact of the pipe, pipe industry will affect the well-being of the entire country in 1964 to carry out rapid In the first successful development of ultra high molecular weight polyethylene pipe and put into industrial production. Premise that time is limited, the molecular weight of about 1.5 million, followed by improving the skills of the craft, the molecular weight of up to one million currently to 400 million or more. Ultra high molecular weight polyethylene pipe to carry pe composite pipe is also very agile quotes, 80 years ago, the world average annual growth rate of 8.5%, 80 years into the future, increase rate as high as 15% to 20%. Steel mesh skeleton plastic composite pipe UHMWPE pipe has been the effect of the national Ministry of Science and Technology as the focus of the implementation of the national program, is new information, new chemical products. An ultra-high molecular weight polyethylene pipe product features 1, high wear characteristics of ultra-high molecular tubes molecular weight of up to 200 million or more (currently there are more than 4.5 million reported in the country), the smallest wear index, it has a very high resistance to sliding friction. Wear 6.6 times higher than ordinary steel, stainless steel, 27.3 times. Phenolic resin is 17.9 times pe composite pipe, six times six nylon, polyethylene four times the service life considerably progressed pipeline. 2, corrosion resistance because of the ultra-high molecular weight polyethylene (UHMW-PE) is a saturated molecular structure commissure, so its high chemical invariance, this product can withstand harsh chemical corrosion, except for some strong acid at high temperatures Under the subtle erosion, but in other lye, acid in from erosion. Can be used in concentrations of less than 80% of concentrated hydrochloric acid, the sulfuric acid concentration of less than 75%, less than 20% concentration of nitric acid are quite the same.
