Analysis of the development of plastic pipe market
With the deepening of the reform and opening up in China and the state of the infrastructure construction of increasing investment, domestic demand for plastic pipe has remained more than 15% of the country's average annual growth rate, especially in the area of urban water supply and drainage pipeline construction, plastic pipe is playing an increasingly important role. Compared with the traditional cast iron pipe, the plastic pipe has a light weight and long service life. Generally speaking, the service life of plastic pipe is more than 50 years, which basically achieves the same service life as the building.
In some special fields, pipelines of plastic raw materials are very large, such as the current most eye-catching radiant floor heating industry, people - Xa or PE - RT with PE pipe as heat pipe, through the floor radiation heating the whole room, has the advantages of comfortable safety, environmental protection and energy saving, has gradually become the first selection of the northern region winter heating.
At the same time, the plastic pipe to further broaden the application area, in addition to the municipal and building to, drainage pipeline, agricultural, water supply, irrigation and drainage pipeline continues to grow, the rural drinking water, solar water pipe, municipal sewage, ground source heat pump pipeline, communications, electricity, gas, heating, medical and other industries the application of a huge increase in proportion. Now plastic pipe has to popularize and apply to a building, drainage, heating buildings, urban gas supply, urban tap water, municipal drainage, drainage, rural drinking water, agricultural irrigation and drainage, electricity, communications, industrial and many other fields.
Plastic pipes not only have the advantage of corrosion resistance, but also the market of plastic material pipes for water delivery is booming with the increasing cost of copper and steel.
PEX tubes are widely used, accounting for about 70%. Steel pipes and copper pipes, by contrast, remain the main material for heating and plumbing, accounting for about 60 per cent of the market. Synthetic materials and PEX are the main raw materials for plastic piping. By 2008, the U.S. high level material intelligence agency (AMI) expected the maximum growth rate of the compound to be 8.4%, the PE-RT tube would grow by 4.8% and the PEX tube would grow by 2.9%. Meanwhile, market researchers predict that the market share of steel tubes will be reduced by 1.6 percent, while the copper tube will be 4 percent lower. Raw material challenges to equipment suppliers.
The pipe diameter of hot water pipe is generally 12-63mm, the most commonly used for external diameter 16mm and 20mm, wall thickness from 2mm to 3.5mm hot water pipe. According to the application, the manufacturer should first make sure that all plastic materials are not suitable for the delivery of drinking water. For example, PEX-a and PEX-b are not suitable for drinking water transport, while PEX-c is suitable. In addition to various types of cross-linking PE, such as PE- RT, PPR, PB, CPVC raw materials and aluminum-plastic composites are also widely used. Drinking water pipes mainly include PE- RT, CPVC and PEX- c, and different types of PEX-a and PEX-b are used in geothermal and heating systems. In order to meet the requirements of high quality and low cost of the product, it is necessary to make a reasonable adjustment to the extrusion line of each pipe.
With the acceleration of China's urbanization construction, it has brought development opportunities to all walks of life, and has benefited a lot in the construction of urbanization. Since the construction of municipal pipe network is an important part of urbanization, the development of plastic pipe industry has also gained a foothold.
As early as 1995, most cities in most cities were paved with water supply, heating, drainage and sewer networks, mainly gray cast iron pipes, ductile iron pipes and cement pipes. Industry insiders predict that such pipes have bad material, shock resistance and bad corrosion resistance. It is imperative to update the pipeline network. Compared with traditional pipe, cast iron pipe and concrete, plastic tubing has obvious substitution advantage, which is another important growth point of the industry.
According to relevant statistics, at present, the low-quality grey cast iron pipe has at least 24,000km, so the urban old pipe network transformation will bring huge space to the development of plastic pipe. At the same time, the construction of urbanization will inevitably increase the investment in the network of natural gas pipeline network and urban drainage system. As the urbanization process accelerates, it is faced with rare development opportunities.
