Application fields of large-diameter plastic-coated steel pipes
Large-diameter plastic-coated steel pipes are mainly made of spiral steel pipes or seamless steel pipes as the base material. It is not recommended to use straight-seam welded pipes. Straight-seam welded pipes are usually not as good as spiral steel pipes in terms of pressure bearing, and the cost is higher than that of spiral steel pipes. Therefore, large-diameter plastic-coated steel pipes are recommended to use spiral steel pipes as the base material, and seamless steel pipes are used when the demand is higher.
The main application areas of large-diameter plastic-coated steel pipes are distributed in HVAC, municipal, industrial, sewage, and other fields. In the fields of HVAC and municipal, large-diameter plastic-coated steel pipes solve the problems of easy rust, easy scaling, and easy pollution of ordinary steel pipes. In addition, the service life of large-diameter plastic-coated steel pipes is 5-10 times longer than that of normal steel pipes, which greatly reduces the cost of pre-installation and pre-buried pipelines, the cost of later maintenance, and the cost of reinstallation and replacement after the service life is reached.
In the fields of industry and sewage, the substances usually discharged and transported have a certain pH value. Under the effect of long-term oxidation, the corrosion rate of ordinary steel pipes is dozens of times faster than the normal rate. The cost of large-diameter steel pipes is very high, and rapid corrosion causes the cost to soar. The expected effect cannot be achieved, and the big picture is lost for the small. The use of large-diameter plastic-coated steel pipes does not reduce the pressure of the pipe itself, and the corrosion of the pipe in pH and long-term oxidation in the air is reduced to almost zero.
Therefore, the service life of the pipe is increased from a few years to decades. The service life has increased tenfold, but the cost is almost the same.
Large-diameter plastic-coated steel pipes have won the favor of the majority of users in HVAC, municipal, industrial, sewage, and other fields with excellent performance, high-cost performance, energy saving and environmental protection, cleaning, and safety.
