The broad prospects of development of plastic pipe
According to the survey of senior U.S. intelligence (AMI), Europe for hot and cold water pipelines transport about 1.6 billion m which half, or 777 million m of plastic tubing pipes. The expected transport the pipeline market's growth rate will reach 0.9%, while the share of plastic pipe pipeline is expected to increase 4.1% in 2008 throughout the hot and cold water. Plastic pipe piping hot water transport mainly used in the field of geothermal facilities, heating facilities and drinking water pipeline. Because of its obvious advantages, plastic pipe used in modern geothermal systems share accounted for 96% of the entire market share.
    In recent years, with the deepening of China's reform and opening up and the national increase investment in infrastructure construction, the domestic demand for plastic pipe has maintained a 15% average annual growth rate of over, especially in the city for construction of drainage network , plastic pipes play an increasingly important role. Compared with traditional cast iron pipe, plastic pipe light bulk density, long life, general plastic pipe service life of more than 50 years, has basically reached the same life and architecture.
    In some special areas, the enormous amount of plastic pipe applications, such as the most eye-catching floor radiant heating industry, people use PE-Xa or PE-RT pipe as a heating pipe, radiant floor heating throughout the room, with comfort and safety, environmental protection and energy saving, and has gradually become the first choice of the northern winter heating methods, and even in some cities, if the new real estate is not installed Warm nobody cares. Meanwhile, the field of plastic pipe applications to further broaden the pipeline, communications, in addition to municipal and construction, drain pipes, agricultural (water supply, irrigation and drainage) pipeline continues to grow, the rural drinking water, solar water pipelines, municipal sewage, ground source heat pump , such as electricity, gas, heating, medical industry a substantial increase in the proportion of. Has universal application to many areas of the buildings, drainage, building heating, city gas distribution, urban water supply, municipal drainage, sewerage, rural drinking water, agricultural irrigation, row, electricity, communications, industrial plastic pipe. "Eleventh Five-Year" period, China's construction plastic pipe annual demand of about 50 million meters. Plastic pipe production in China in 2010 will reach 4.5 million tons, will reach 600 million tons by 2015, when China will become the world's largest plastic pipe production.
    Plastic pipe not only has the advantage of corrosion-resistant, and with the ever-increasing costs of copper and steel, water conveyance pipeline of plastic pipe market is booming. Cincinnati Extrusion Technology Co., Ltd. to provide customers with tailor-made extrusion lines for different materials such as PEX, PP, PE-RT composite materials to meet the growing market demand.
    , PEX pipes are widely used, accounting for about 70%. In contrast, steel and copper is still the main material of the heating and sanitary pipes, accounting for about 60% of the entire market share. The main raw material of synthetic materials and PEX plastic pipe. The highest growth rate of the composite tube is expected to reach 8.4% to 2008, senior U.S. the material intelligence agencies (AMI), PE-RT pipe will be increased by 4.8%, PEX pipe will grow by 2.9%. At the same time, market researchers forecast the market share of steel pipe will be reduced by 1.6%, copper will be reduced to 4%. The challenge of raw materials to equipment suppliers.
    The hot water pipe diameter production range is generally 12 ~ 63mm, the most commonly used for the outer diameter of 16mm and 20mm wall thickness from 2mm to 3.5mm hot water pipes. Depending on the application, the manufacturer should first clear plastic raw material production pipe are not applicable to the delivery of drinking water. For example, PEX-a and PEX-b is not suitable for drinking water, transport, and PEX-c suitable. In addition to the various types of cross-linked PE, PE-RT, etc., PP-R, PB, C-PVC materials and aluminum-plastic composite materials are widely used. Drinking water pipes PE-RT, C-PVC and PEX-c, different types of PEX-a and PEX-b is used for geothermal heating system. In order to meet the requirements of the pipe manufacturer low-cost, high-quality product at the same time, it must be different for each pipe extrusion production line for the processing of raw materials to make reasonable adjustments.
