How do plastic products seize the commanding heights of the future building materials market?

Engineers from Germany stood on the giant steel strip corrugated and told reporters that the pipe corrugated pipe made of composite plastic is very strong due to the internal use of high-strength corrugated ribs. Due to its advanced technology, the tube has an inner diameter of up to 4 meters.

According to reports, the steel belt corrugated pipe manufacturing process has no waste water and waste gas, and the process is environmentally friendly. It is especially suitable for damage, maintenance and repair of the original traditional pipeline. For example, if the old cement pipe is broken, a bellows with a slightly smaller pipe diameter can be passed through without knocking the entire cement pipe. Repairing with bellows does not require large-area construction, and replacing a section is enough to solve the problem. Using this technology to repair old and worn pipes can greatly reduce costs.

In foreign countries, plastic pipes are constantly replacing pipes of metals or other traditional materials, and they are developing very rapidly. According to relevant data, during the period of 1980-1990, except for plastic pipes, the growth rate of pipes of various materials was less than 2%, but the growth rate of plastic pipes was four times that of other various pipe growth rates. 8%. Since the 1990s, the demand for plastic pipes has continued to grow at a rate of 4.2% per year, and its output has increased at an annual rate of 8%.

Nowadays, more and more plastic products are being used in various buildings in China. According to reports, in the 1980s, the introduction of production technology and industrial production of building water supply and drainage pipes, profiled doors and windows and other products have been widely used, and become a new type of building materials encouraged and actively promoted by the state. At present, the proportion of plastic pipes and profiles used in construction pipes and doors and windows has reached 30% and 15% respectively. In 2002, the total output of plastic pipes and profiles reached 2.5 million tons.

Plastic pipes are increasingly favored by the people and the relevant government departments for their advantages of low energy consumption, low environmental pollution and good product performance. At the same time, the Ministry of Construction issued a notice to strengthen the production management and promotion of plastic pipes. It can be seen that plastic pipes have great market development potential in China in the future. With the country's increasing emphasis on environmental protection, the country will invest heavily in the construction of drainage networks in the next five years, which means that the market for the development of plastic buried drainage pipes is increasing.

China's "National Chemical Building Materials Industry "10th Five-Year Plan" and the 2015 Development Plan Outline clearly state that by 2005, the market share of plastic pipes in various types of pipelines across the country will reach more than 50%. In 2015, 80% of the national construction drainage pipes were made of plastic pipes, and the cast iron pipes were basically eliminated. 90% of the construction wire threading and sheathing pipes were made of plastic pipes, and 80% of the building rainwater drainage pipes were made of plastic pipes, building cold water, hot water supply and heating pipes. % use plastic pipe to basically eliminate the galvanized pipe. 80% of urban water supply pipes (below DN400mm) use plastic pipes, 90% of village water supply pipes use plastic pipes, more than 40% of urban gas pipes use plastic pipes, and the use of plastic pipes for urban drainage pipes reaches 50%.
