Use characteristics and application fields of large-diameter plastic-coated steel pipes

In the installation of large-diameter plastic-coated steel pipes, there are many installation methods and good use effects. Large-diameter plastic-coated steel pipes are used in fire-fighting pipelines and power pipeline installations. Both play an important role in underground mining.

The application of large-diameter plastic-coated steel pipes is very common, which lies in the specific characteristics of the product itself. Large-diameter plastic-coated steel pipe is a new type of composite pipe material that is melted, sprayed, or adsorbed on the inner and outer walls of the epoxy resin powder coating with advanced technology and cured at high temperatures. As a replacement product for ordinary pipes, it has strength and Rigidity and has the advantages of the very smooth inner wall of plastic water pipes, good self-lubrication, no rust, no scaling, small fluid resistance, abrasion resistance, corrosion resistance, good antibacterial hygiene performance, and flexibility.

Large-diameter plastic-coated 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. Longitudinal welded pipes are generally not as good in bearing pressure as spiral steel pipes, and the cost is higher than spiral steel pipes. Therefore, For large-diameter plastic-coated pipes, it is recommended to use spiral steel pipes as the base material, and seamless steel pipes are used when the needs are high.

Large-diameter plastic-coated steel pipes are mainly used in HVAC, municipal, industrial, sewage, and other fields. In HVAC and municipal fields, large-diameter plastic-coated pipes solve the problems of easy rust, scaling, and pollution in ordinary steel pipes. Moreover, the service life of large-diameter plastic-coated pipes is 5-10 times that of normal steel pipes, which greatly reduces the cost of pre-installation, pre-embedding, later maintenance costs, and reinstallation and replacement costs after the service life is over.

In the fields of industry, sewage, and other fields, the substances discharged and transported usually have a certain pH. Under the effect of long-term oxidation, the corrosion rate of steel pipes is usually dozens of times faster than the normal rate. The cost of large-diameter steel pipes is very high, and the rapid corrosion causes the cost to soar. Can not achieve the expected effect, because of small losses. The use of large-diameter plastic-coated pipes does not reduce the pressure of the pipe itself and reduces the pipe's pH corrosion and long-term oxidation in the air to almost zero.

Therefore, the service life of the pipeline has been increased from several years to several decades. The useful life has doubled tenfold, but the cost is about the same.

Large-diameter plastic-coated pipes have won the favor of users in HVAC, municipal, industrial, sewage, and other fields due to their excellent performance, high-cost performance, energy saving, environmental protection, and cleaning safety.
