Material of inner (outer) coated steel pipes for water supply: PE, PEX, EP, PU, PO; Standard length: 6m-12m; Working temperature: cold water 0 ° C~40 ° C; Working pressure: 16MPa (ordinary type), 2 5MPa (thickened type); Connection method: threaded connection, groove connection, flange and butt welding connection;
Features: Hygienic, non-toxic, no accumulation, no breeding of microorganisms, ensuring liquid quality. Resistant to chemical corrosion, soil and marine life corrosion, and cathodic stripping. The installation process is mature, convenient and fast, and similar to the connection of ordinary galvanized pipes. Weather resistant grade, suitable for harsh environments such as deserts and salt alkali. Smooth pipe wall, improved conveying efficiency, and long service life;
Application scope: It can be used in fields such as civil water supply, industrial water supply, rainwater collection and transportation, seawater utilization, oil and natural gas, etc;

The inner (outer) plastic coated steel pipes for water supply not only have the high strength of steel pipes but also have the chemical corrosion resistance of engineering plastics, and their surface coating thickness reaches 0.3-1mm. When conveying various fluids, the resistance coefficient is small, and bacteria and mold do not breed; Having good anti scaling ability, it can increase the fluid volume transported by 7% to 12% compared to steel pipes of the same diameter in general, and reduce the power consumption of transportation by 15%; The service life can reach 50-100 years, so it can be said that coated steel pipes are a new type of pipeline with high efficiency, energy conservation, environmental protection, and corrosion prevention. Coated steel pipes have been widely used in various industries in industrialized countries, such as oil and gas pipelines and water supply and drainage pipelines- Some countries have also adopted coated steel pipes for the extraction of manganese ore from the seabed and for atomic power plants. On the basis of the introduction, China's production of coated steel pipes has made innovations and improvements. In recent years, the quality of plastic powder coatings in China has made significant progress. Several commonly used plastic powders, such as epoxy resin (EP) and polyethylene (PE), have become increasingly mature in their domestic formulations, and reliable data has been obtained in their applications. Their quality has reached the international advanced level.
