Plastic tube with a light weight, corrosion resistance, small water loss, easy installation, by the pipeline engineering of all ages, at the same time due to the traditional plastic pipe metal pipe compared to the production of less energy consumption, less environmental pollution, increasingly subject to government and related industries attention. Overseas, the plastic pipe is constantly replace metal pipe or other traditional materials, developed very rapidly. From 1980--1990 years of the decade except for plastic pipes, the sum of the growth rate of a variety of other pipe materials less than 2%, but the growth rate of plastic pipe has reached more than 8% in recent years it has reached about 15%, the output value also greatly improved.
First, the domestic production capacity situation
    China since the 1970s began producing plastic pipes, the early eighties in engineering construction application. The past two decades, plastic pipe has been great development, not only in quantity, but also in the varieties and specifications have been greatly developed. Now, the national plastic pipe production line is about more than 2000, which accounts for about 15% of the imported equipment, all kinds of plastic pipe production capacity reached 1.65 million tons, the actual output is about 100 million tons. Wherein, PVC-U pipe 500,000 tons, accounting for 50%; PE pipe 36 million tons, accounting for 36%. In recent years, with the construction industry to become an important pillar of national economy, the rapid development of industry and the housing industry, building interior plastic tube rapid development, has become a hot spot of investment.
    1, rigid polyvinyl chloride pipe (PVC-U).
    Rigid polyvinyl chloride pipe (PVC-U) is mainly used for urban water supply, urban drainage, water supply and other construction and building drainage pipes. At present, some cities PVC-U building drains utilization rate of over 90%; in urban water supply pipe, PVC-U pipes already laid more than 5000 km. Domestic PVC-U pipe production enterprises more than 600, the annual production capacity reached 100 million tons (the actual production of about 500,000 tons). PVC-U pipe production capacity of 10,000 tons / year of enterprises have more than 30; the scale of 5000-10000 tons / year, nearly 60 companies. PVC-U production equipment basically realized the localization.
    2, a polyethylene tube (PE).
    Polyethylene (PE) pipes are mainly used for city gas, urban water supply, urban drainage, water supply and other building pipelines. At present, domestic PE pipe manufacturers nearly more than 150 (which is the production of nearly 100 rural water supply and agricultural irrigation pipe), the annual production capacity of 450,000 tons, the production scale of 5,000 tons / year, there are 10 over.
    3, plastic composite pipe.
    At present, plastic composite pipe production enterprises nearly 300, the production line reached more than 300 (including imported equipment accounted for 10% of domestic equipment accounted for 90%), lap welding production line 70%, butt welding production lines accounted for 30% of production capacity to reach 800 million m / year.
    4, cross-linked polyethylene pipe.
    At present, cross-linked polyethylene pipe production enterprises nearly 100, more than 100 production line (production line which imports more than 10), the production capacity will reach 500 million m / year.
    5, random copolymer polypropylene tube (PP-R).
    Domestic copolymer PP-R raw materials compared with foreign brand PP-R pipe Compound in performance, there are some gaps in performance. Therefore, the current domestic production of PP-R pipe most raw materials are imported from abroad. At present PP-R pipe production enterprises nearly 100, nearly 120 production line (including imported equipment more than 10), the production capacity will reach 500 million m / year.
Second, problems
    1, less variety of raw materials, the quality of instability, there is a certain gap with foreign brands Compound, causing some raw materials imported.
    2, the production scale is generally small, amounting to less than the economic scale of production, is not conducive to improving product quality and lower prices.
    3, tube less varieties, specifications incomplete, can not meet the engineering needs.
    4, product standards, design and construction specifications lag, lack of professional engineering and technical personnel training.
    5, the lack of standardization of market management, project construction blind, lack of unified planning, resulting in excess capacity in some areas, a serious shortage of capacity utilization of production facilities. Coupled with inadequate supervision and management of quality, counterfeit products flooding the market.
Third, the development trend
    Development of plastic pipe, currently mainly UPVC pipe and PE pipe-based, and vigorously develop new composite, modified plastic pipe. In 2005, the various types of plastic pipe in the pipe market share of more than 50% in the national new construction, renovation, expansion project, 70% of building drainage pipes plastic pipe; building water supply, hot water supply and heating pipes using 60% plastic pipe; wire threading tube 80% of the plastic sheathing tube; 50% of the construction of rainwater drainage pipes plastic pipe; urban water supply pipe (DN400mm or less) 50% of the plastic tube; village water supply pipes 60% of the plastic tube; urban drainage channel 20 % of the plastic tube; city gas pipeline (low pressure pipe) 50% of the plastic tube. By 2010, the main plastic pipe products to meet market requirements, market product range, quality, grade and level of support has significantly improved, the overall level close to the international advanced level. The national new construction, renovation, expansion project, building drains 80% of the plastic tube; building water supply, hot water supply and heating tube 80% of the plastic pipe; wire sheathing tube 90% of the plastic tube; building rainwater drains 70% plastic pipe; urban water supply pipe (DN400mm or less) 70% of the plastic pipe, village water supply pipe 70% of the plastic tube; urban drainage 50% of the plastic tube; city gas pipeline (low pressure pipe) 60% of the plastic tube.
Fourth, the development proposals
    1, the adjustment of product structure. Construction administrative departments at all levels and relevant departments should formulate relevant policies to limit and eliminate backward technology, high energy consumption products, and actively encourage and support the development of plastic pipe.
    2, improve the quality management measures to regulate the sales market. Plastic pipe manufacturer shall ISO9000 series of quality standards, establish and perfect quality assurance system and after-sales service commitment to providing high-quality pipes and fittings for construction projects; relevant departments should strengthen supervision and inspection of plastic pipe quality, specification sales market.
    3, strengthen market guidance. We should be actively pursued plastic pipe production and application of technical discussions and exchanges, reinforced plastic pipe technology training and application engineering pilot demonstration work, and guide the development of plastic pipe.
