Prospects: plastic manholes are new building materials promoted in the "11th Five Year Technical Bulletin" policy of the Ministry of Construction. With the gradual transformation of rainwater and sewage confluence into rainwater and sewage separation as a major municipal project in various cities in China, the application of plastic manholes is also increasingly widespread. According to statistics, the use of plastic pipes in urban drainage pipelines has reached 50%, What is the prospect of plastic manhole?

In 2017, there were about 3000 large-scale plastic pipe manufacturers in China, with an annual production capacity of more than 15 million tons. Among them, about 300 enterprises have an annual production capacity of more than 10000 tons, and more than 20 enterprises have an annual production capacity of more than 100000 tons. The development of large-scale enterprises is the direction and increasing. The plastic pipeline industry is booming with the huge market demand of sponge cities, urban underground utility tunnels, prefabricated buildings for residential industrialization, and the output has exceeded 15 million tons.

In 2015, 85% of building drainage pipes, 80% of building rainwater drainage pipes, 50% of urban drainage pipes, 85% of building water supply, hot water supply and heating pipes, 80% of urban water supply pipes (below DN400mm) and 90% of village and town water supply pipes were plastic pipes in new, reconstruction and expansion projects nationwide, The application amount of urban gas plastic pipes (medium and low pressure pipes) reaches 40%, and 90% of building wire threading protective sleeves are plastic pipes.

Plastic pipes can be divided into PVC pipes, PE pipes, PP pipes, etc. according to their materials. Among them, PVC pipe system is the earliest developed and has the largest market share, reaching 36%. PE and PP pipes started late, but developed rapidly. Domestic plastic pipe products have formed a tripartite confrontation. With the improvement of China's urbanization rate, the demand for urban water supply and the scale of water supply have increased year by year. In addition to the renewal of aging water supply pipelines and the laying of urban drainage pipelines, the demand for water supply and drainage pipelines has increased significantly.

With the unique advantages of light weight, good toughness, low temperature resistance, non-toxic, high impact strength, and low price, PE pipes are widely used in gas pipes, drainage pipes, drinking water pipes, industrial corrosion resistant pipes, etc., with huge market demand and market share expected to further increase.

At present, the urbanization level of China is only about 58.5%, while that of developed countries is more than 70% on average. Pipeline is a basic building material, a three-way connection for any building, and an indispensable blood vessel in urban construction. It can be predicted that the process of super large-scale urbanization will bring huge demand for the pipe industry in the next ten years at least.
