Release time:
2020-10-12
The plastic-coated composite pipe production process is currently one of the most advanced anti-corrosion technologies. It combines the superior mechanical properties of steel with the outstanding chemical resistance of polymer materials, significantly extending the service life of steel pipes. This technology offers unique advantages such as exceptional resistance to acids and alkalis, excellent wear resistance, no scaling, enhanced lubricity, and resistance to negative pressure. As a result, it can replace lined plastic pipes, galvanized pipes, stainless steel pipes, and copper pipes. Plastic-coated steel pipes exhibit excellent corrosion resistance and low friction, making them ideal for transporting media such as water supply and drainage, seawater, warm water, oil, and gases.

Coated steel pipes exhibit excellent corrosion resistance and low friction, making them ideal for transporting media such as water, seawater, warm water, oil, and gases.
Plastic-coated composite pipe Polymer anti-corrosion powder-coated composite pipes are steel-plastic composite pipes manufactured through a process that involves welding steel pipes as the base material, followed by double pre-treatment—both sandblasting and chemical treatment—preheating, internal and external coating, curing, and post-processing. These pipes exhibit excellent overall performance, featuring strong corrosion resistance and mechanical strength, as well as good chemical stability and water resistance. They also offer benefits such as drag reduction, anti-corrosion, pressure resistance, and antibacterial properties.
It is generally not constrained by the conveyed medium. The coating layer exhibits extremely strong adhesion to steel, and the coating material used in coated composite pipes—epoxy resin—is suitable for working environments below 80 degrees Celsius. The steel pipe coating boasts exceptional adhesion, high hardness, excellent impact resistance, and superior chemical corrosion resistance. Coated composite pipes, depending on the specific material used, are also well-suited for ultra-low temperature operating conditions. The coatings feature exceptionally high adhesion, high hardness, excellent impact resistance, and outstanding chemical corrosion resistance. Based on different application requirements, our company has developed a wide variety of products that can be extensively used in civil water supply and drainage systems, fire protection pipelines, fluid transport in chemical enterprises, as well as in water supply and drainage systems for highways and subway tunnels.
