What is the difference between PSP steel plastic composite pressure pipe and galvanized plastic composite pressure pipe?
Galvanized lined plastic composite pipe is made of hot-dip galvanized pipe as substrate and coated with powder melt spraying or substrate rotating heating technology. The production process in order to improve the binding fastness of plastics and steel, first of all requirements of the galvanized steel pipe galvanized layer wall removed, a hair in the inner wall of the blast, burrs, this increased production costs, energy production, and the product has two layers, namely the plastic pipe layer and the inner layer of the outer layer, whether it is melt coating or substrate rotation heating technology
Steel plastic composite pressure pipe and galvanized steel plastic composite pipe for drinking water pipeline replacement products, completely solve the two pollution problems caused by the quality of galvanized pipe, is a revolution in the pipeline industry, two have high mechanical strength, pressure stable performance, long service life, but the two have the essential difference.
The inner wall is made of no fixed diameterA wall thickness is not uniform, smooth, easy to scale, easy to breed bacteria, fluid resistance, head loss, and lining between the plastic layer and the steel layer without adhesive, so use in a hot water system will occur when the inner and outer layer of expansion and contraction are layered phenomenon, at the same time galvanized plastic lining pipe wall without protective layer easy to rust, affect the life of.
As the traditional galvanized steel pipe replacement, PSP steel plastic composite pressure pipe and galvanized steel plastic composite pipe in drinking water pipeline has been widely used in the field, compared with the pure plastic pipe and galvanized steel pipe, galvanized steel pipe of the two service life and corrosion resistance are better than the traditional, high temperature, high pressure resistance, environmental stress stress cracking resistance and creep resistance than the pure plastic pipe, especially steel plastic composite pipe with galvanized steel and pure plastic pipe comprehensive excellent performance from the health, life, energy consumption and production cost, corrosion resistant, is better than that of zinc lining plastic composite pipe for a higher level of drinking water pipeline, worth vigorously promote the use of.
