With the rapid development of economy, the society is progressing continuously. The development of circular economy, the construction of resource-conserving and environment-friendly society is the inevitable way to ensure that our human beings can enjoy the achievements of civilization for a long time. Therefore, a variety of conservation resources, environmental protection products continue to develop into the market, greatly encouraged by the Government and people of all ages.
In the past, the construction of the drainage area, the traditional cast iron pipe and steel pipe has been firmly in the position of the boss, the state of the application of plastic pipes has been increasing attention, and vigorously support the development of plastics pipelines, production and promotion, and successfully developed a polyethylene (PE), polypropylene (PP), Hard polyvinyl chloride (UPVC) and other materials of plastic pipe, the state even put forward the "plastic substituting steel" promotion call, in this environment, a variety of new types of plastic pipes began to its more superior performance and cheaper prices began to occupy the market widely. So far, the use of uPVC pipe is the largest, but the uPVC pipe in the production of heavy metal additives, the use of monomer vinyl chloride may also seep into the transport medium, thus causing harm to the human body, and the uPVC tube in the incineration will produce a large number of harmful gases and serious pollution of the environment. With the improvement of people's environmental awareness and the need of environmental protection, the application of uPVC pipe is more and more restricted, and HDPE pipe is gradually replaced.
It is the existence of this trend, set practical, environmental protection, safety in the application of high-density polyethylene (HDPE) pipe development rapidly. HDPE is a high degree of crystallization, non-polar thermoplastic resin, HDPE pipe through the hot extrusion molding, with corrosion resistance, smooth inner wall, small flow resistance, high strength, good toughness, light weight and so on. The use of a full set of imported German pipe Automation extrusion line, the production of products are widely used in municipal drainage, water, gas and other fields.
