Plastic-coated composite steel pipes are suitable for water delivery temperatures between -30°C and 80°C, exhibiting excellent chemical stability and water resistance, and meet safety assessment standards for drinking water distribution equipment and protective materials. This type of plastic-coated steel pipe overcomes the shortcomings of ordinary steel pipes and is lightweight, making it easy to carry, install, and maintain.
In my country, three-layer PE-coated steel pipes were first used in oil and gas systems.
- Texture: Rough particles may be mixed with impurities.
- Odor: The primary material of plastic-coated steel pipes is polypropylene, and high-quality steel pipes are odorless.
- Extrusion Hardness: Plastic-coated steel pipes have good hardness and will not deform if squeezed.
Hot-Dip Coating of Plastic-Coated Steel Pipes
Fluidized bed hot-dip coating and single-shot hot-dip coating of plastic-coated steel pipes: Fluidized bed hot-dip coating and single-shot hot-dip coating are available for flanges and pressure tanks. Coating lengths are 6m, 9m, and 12m. Coating wall thickness varies, ranging from 100 microns to 500 microns, with a maximum thickness of 350 microns. The performance of plastic-coated steel pipes far exceeds that of plastic-lined steel pipes. Due to the higher price of the coating, complex process, and high cost, the market price of plastic-lined steel pipes is slightly higher than that of plastic-lined steel pipes. Plastic-coated steel pipes offer higher quality than plastic-lined steel pipes, with a lower failure rate and longer service life. This coating is characterized by simple application, pollution-free operation, excellent impact and bending resistance, and high temperature resistance.
Features of plastic-coated steel pipes: fast curing speed, short curing time, high coating efficiency, and suitability for assembly line operations.
Plastic-coated steel pipes also offer excellent mechanical and physical properties: fast curing speed, short curing time, high coating efficiency, and suitability for assembly line operations. Excellent mechanical and physical properties, including excellent corrosion resistance, including resistance to acids, alkalis, salts, oils, and water. It provides long-term corrosion protection over a wide temperature range. Every organic coating has a certain service life. It’s safe to say there’s no such thing as a bad coating. Extending the lifespan of coatings is a perennial topic in the coatings industry. Different products have different requirements for coating lifespans. For example, the service life of household appliances like refrigerators, air conditioners, washing machines, microwave ovens, and dishwashers generally exceeds 10 years.
