The development prospect of the hottest plastic pi

  • Detail

The development prospect of plastic pipes is broad

according to the investigation of American advanced material intelligence (AMI), the total length of pipelines used for cold and hot water transmission in Europe is about 1.6 billion m, and half of them, 777 million M, are plastic pipes. It is expected that the growth rate of the whole cold and hot water transmission pipeline market will reach 0.9% by 2008, while the share of plastic pipe pipeline is expected to increase by 4.1%. The use of plastic pipes for hot water transmission is mainly used in geothermal facilities, heating facilities, drinking water pipelines and other fields. Due to its obvious advantages, the share of plastic pipes used in modern geothermal systems has accounted for 96% of the total market share

in recent years, with the deepening of China's reform and opening up and the increasing investment of the state in infrastructure construction, the domestic demand for plastic pipes has maintained an average annual growth rate of more than 15%, especially in the construction of urban water supply and drainage pipes, plastic pipes play an increasingly important role. Compared with traditional cast iron pipes, plastic pipes have light unit weight and long service life. Generally speaking, the service life of plastic pipes is more than 50 years, which basically reaches the same service life as buildings

in some special fields, the application of plastic pipes is very large. For example, in the current most eye-catching floor radiant heating industry, people use PE XA or PE RT pipes as heating pipes to heat the whole room through floor radiation, which has the advantages of comfort, safety, environmental protection and energy conservation. It has gradually become the first choice for winter heating in northern areas. Even in some cities, if new buildings are not installed with floor heating, no one will pay attention to it. Driven by strong market demand, enterprises engaged in the production of plastic pipes for floor heating broke out almost overnight. Among them, Qinhuangdao Hongyue Plastic Co., Ltd. has become the largest production base of floor heating pipes in China. In 2008, the production and sales of PE XA pipes of the company ranked first in the country

at the same time, the application field of plastic pipes has been further expanded. In addition to the continuous growth of municipal and building water supply and drainage pipelines, agricultural (water supply, irrigation and drainage) pipelines, the application proportion of rural human and livestock drinking water transformation, solar water transmission pipelines, municipal sewage, ground source heat pump transmission pipelines, communications, electricity, gas, heating, medical and other industries has increased significantly. Now plastic pipes have been widely used in many fields, such as building water supply and drainage, building heating, urban gas transmission, urban tap water, municipal drainage, sewage discharge, rural drinking water transformation, agricultural irrigation and drainage, electricity, communication, industry and so on

during the "Eleventh Five Year Plan" period, China's annual demand for building plastic pipes is about 5billion meters. By 2010, the output of plastic tubes in China will reach 4.5 million tons, and by 2015, it will reach 6million tons. At that time, China will become the country with the largest output of plastic tubes in the world, which consists of five vertical research laboratories, namely, thermal analysis of thin film materials, preparation and processing of material samples for which thin film materials are no problem, electromagnetic analysis of thin film materials, mechanical analysis of thin film materials, and optical analysis of thin film materials

plastic pipes not only have the advantage of corrosion resistance, but also with the continuous increase of copper and steel costs, the market of plastic pipes for water transmission is booming from the perspective of VOCs control. Cincinnati Extrusion Technology Co., Ltd. provides customers with customized extrusion lines for different raw materials such as PEX, PP, PE-RT and composites to meet the growing market demand

among them, PEX tube is widely used, accounting for about 70%. In contrast, steel pipes and copper pipes are still the main materials for heating facilities and sanitary pipes, accounting for about 60% of the total market share. Synthetic materials and PEX are the main raw materials of plastic pipes. The extensometer of total elongation should have a gauge length of at least 100mm. By 2008, the American advanced material information agency (AMI) predicts that the maximum growth rate of composite pipe will reach 8.4%, PE-RT pipe will increase by 4.8%, and PEX pipe will increase by 2.9%. At the same time, market researchers predict that the market share of steel pipes will decrease by 1.6%, while that of copper pipes will decrease by 4%. Challenges of raw materials to equipment suppliers

the production range of hot water pipe diameter is generally 12 ~ 63mm, and the most commonly used are hot water pipes with outer diameters of 16mm and 20mm and wall thickness from 2mm to 3.5mm. According to different applications, manufacturers should first make it clear that not all pipes produced from plastic raw materials are suitable for the transportation of drinking water. For example, PEX-a and PEX-b are not suitable for drinking water transmission, while pex-c is suitable. In addition to various types of cross-linked PE, such as PE-RT, PP-R, Pb, c-pvc raw materials and aluminum-plastic composites are also widely used. Drinking water pipes mainly include PE-RT, c-pvc and pex-c. different kinds of PEX-a and PEX-b are used in geothermal and heating systems. In order to meet the requirements of pipe manufacturers for high quality and low cost products, each pipe extrusion line must be adjusted reasonably according to the different processing materials
