Welcome to our introduction site of the production process of plastic-coated composite steel pipes. Here, we will show you how through a series of exquisite craftsmanship, an ordinary steel pipe can be turned into a beautiful landscape, bringing comfort and safety to our lives.
First, the steel pipe is pickled to remove oxide scale and rust, and then degreased in a high-temperature hydrostatic bath to ensure that the surface of the steel pipe is clean. Then, through sandblasting, the surface roughness of the steel pipe reaches the national standard, laying a solid foundation for the plastic coating composite process.
The prepreg is then heated and melted by a drum and sprayed on the surface of the steel pipe to allow the prepreg to fully blend with the steel pipe. Subsequently, the steel pipe is put into a polyurethane powder reaction furnace, and the surface of the steel pipe is covered with a uniform and thick polyurethane coating through high-temperature melting and full plasticization.
Finally, the coated steel pipe is subjected to a series of treatments such as high-temperature curing, cooling, and slicing, and it is cut into the required length, and strict quality inspection is carried out before leaving the factory to ensure that each steel pipe meets the national standard and can be used with confidence.
Through our exquisite technology, plastic-coated composite steel pipes not only have excellent corrosion resistance and wear resistance, but also have good thermal insulation, noise reduction, flame retardant and other properties, which are more and more favored by the market. Let us look forward to this green and environmentally friendly, high-quality plastic-coated composite steel pipe, which will bring more surprises and comfort to our lives!
