As a new type of pipe that replaces traditional cement pipes and steel pipes, plastic pipe pipe has the characteristics of excellent performance, safety and reliability, convenient installation, mature technology, no corrosion and long service life. It can be widely used in indoor and outdoor water supply and drainage, building water supply and drainage, Wide range of gas pipes, sewage pipes, etc.
In particular, high-density polyethylene (HDPE) plastic pipes have many advantages such as heat resistance, aging resistance, high mechanical strength, environmental stress crack resistance, good creep resistance, and good toughness and stiffness. International and national standards require that the cost can be reduced by about 12% compared to the steel pipe currently in use, the working life can be up to 50 years (the steel pipe is generally 20 years), and the maintenance cost is low. The increasing demand for HDPE pipes in the market is due to the increased capital investment in the non-civil construction projects mentioned above. In the future, HDPE pipes will play an increasingly important role in today's non-civil construction projects led by concrete pipes (cement pipes) and metal pipes.
According to statistics, in all applications of HDPE pipes, the share of natural gas transmission is much larger, and the share of drainage/water supply applications for roads and street buildings is much smaller. Compared with traditional pipes, this plastic pipe has lower procurement costs and installation costs. Since HDPE pipes are less expensive, have better corrosion resistance and have a longer service life than other types of pipes, it is expected that the demand for HDPE pipes will continue to grow in the near future.
