After years of efforts, China has established to polyvinyl chloride (PVC) pipe, polyethylene (PE) pipes and polypropylene (PP) tube-based processing and application of plastic pipe industry. Judging from the material now PVC-U, PE and PP plastic is still the largest common species, to 2005, for example, PVC pipes account for about 55% of the total, are still a leading product; PE about the total pipeline 25% or more; PP pipe about 10% of the total. PVC pipe in hard products (PVC-U) for the majority, mainly for water supply, drainage and jacket and so on; PE pipe is mainly used for water and gas transport; PP tubing PP-R as the main species, which are mainly used in building cold, water transport, in after as short-term behavior of individual enterprises only pay attention to the neglect of quality in the developing obstructed, the made greater progress, has gradually resumed its impact. Some new material also has a large pipeline of technological progress, plastic and plastic, plastic and metal, plastic and other materials developed rapidly in the composite pipe, cross-linked polyethylene (PEX), high molecular weight polyethylene (UHMWPE), acrylonitrile - butadiene - styrene copolymer (ABS), polybutylene (PB), resistant polyethylene (PE-RT), chlorinated polyvinyl chloride (PVC-C) and the amount of modified materials also increased. In recent years, pipeline structure is no longer unified by solid wall pipe, corrugated pipe to the increased use in the construction of drainage within the spiral structure in its particular strengths, Pipe in drainage, sewage and water consumption of more and more areas. China has become one of the largest varieties of plastic pipe. Further broaden the application areas In addition to municipal and construction to the drain pipes are still major uses, agricultural (drinking water, irrigation and drainage) pipeline continues to grow, municipal sewage, gas, heating, urban excavation, communications, electricity, mining and other industry applications proportion further increased. Plastic pipes are used in construction to the universal, drainage, building heating, city gas transmission, gas transmission in rural biogas, urban tap water, municipal drainage, sewage, drinking water in rural reconstruction, agriculture, irrigation, drainage and power, communications, industry, etc area. Some people praised the city's vascular plastic pipe, plastic pipe and our lives are inextricably linked. Accelerating scientific and technological progress "15" period, the plastic pipe industry, growth, and promote the industry's technological progress. In particular the increase in international exchanges, many companies attach great importance to the international forefront of technology, emphasis on new product development and introduction of new technologies and introduction of advanced processing equipment, but also constantly developing new products to enhance strength, a number of large enterprises have their own advanced level of research and development center, has strong technical strength, the domestic plastic industry, Zhong Guan Dao Yijingyongyou into more than 300 Invention, Utility patents, and some independent intellectual property rights a leader in the 国际 level of technology in oversea developed countries the gap is gradually narrowing, has been from the simple replacement of products imported into international export. Variety of plastic pipe, structure, new materials, new technologies, new technology and patents are more and more different types of plastic pipe used in a different play their respective advantages. |
