Manufacturer's price for epoxy powder anti-corrosion steel pipes for drainage

Description :

　　Epoxy powder coating is a type of coating mainly composed of powder plastics, and its performance is basically determined by the properties of the main plastic. Plastics can be divided into two categories based on their performance changes after heating: thermoplastic plastics and thermosetting plastics. Thermoplastic is generally made from polymer resins as the basic component, with a small amount of stabilizers, lubricants, or plasticizers added (or not added). The characteristic of this type of plastic is that it softens when heated, has plasticity, and can be repeatedly molded. Typically, thermoplastic materials have excellent chemical corrosion resistance, toughness, and elongation.

　　Common thermoplastic materials include polyethylene, polyethylene, polyvinyl chloride, polystyrene, polycarbonate, polytetrafluoroethylene, nylon, polyphenylene ether, chlorinated polyether, ethylene vinyl acetate copolymer, etc. Thermosetting plastics are made from concentrated cluster resin as the basic component, with additives such as fillers and curing agents added. Thermosetting plastics have good curing leveling and wetting properties due to their small molecular weight, which makes them have strong adhesion to the pipe body when coating steel pipes and can achieve a smoother plastic film surface for the coated steel pipes. Common thermosetting plastics include epoxy resin, phenolic resin, resin, etc. Epoxy powder anti-corrosion steel pipe. The 3PE anti-corrosion coating on the outer wall of epoxy powder anti-corrosion steel pipe is used in different working environments to slow down or prevent the pipeline from being eroded and deteriorated by the chemical and electrochemical action of the external medium or the metabolic activity of microorganisms. Two or three layers of polyethylene (3PE) are coated on its outer wall to achieve pipeline anti-corrosion, which can extend the service life of the anti-corrosion pipeline by 3-5 times.

　　The 3PE anti-corrosion steel pipe coating has good resistance to soil, water, and mold corrosion and construction performance. Has good electrical insulation properties. When used in conjunction with cathodic protection, the anti-corrosion coating should have a certain ability to resist cathodic peeling strength. Has sufficient mechanical strength. Greatly improved the impact resistance of the 3PE anti-corrosion coating to ensure that the coating is undamaged under handling and soil pressure. One of the basic methods for anti-corrosion steel pipes is to evenly and densely apply paint on the surface of the rust removed anti-corrosion steel pipe to isolate it from various corrosive media. It has the advantages of no solvents, no pollution, energy and resource savings, reduced labor intensity, and high mechanical strength of coating film. Widely used in petroleum, natural gas, chemical, coal mining, water supply and drainage and other engineering projects.

　　Epoxy powder anti-corrosion steel pipes with internal and external coating not only have excellent inductive function and strong corrosion resistance, but also can be used at an external temperature of -40 ℃ - Celsius degrees. The applicable water delivery temperature is -30 ℃ - ℃. Epoxy powder anti-corrosion steel pipes have high-end characteristics such as no solvents, no pollution, energy and resource savings, reduced labor intensity, and coating mechanical strength. FBE epoxy powder for anti-corrosion steel pipes is first fully fluidized in a fluidized bed, and then electrostatically sprayed to make the powder particles negatively charged and uniformly adhered to the surface of the preheated steel pipe that is grounded. Regarding a small amount of loose powder, it can be recycled through a recycling system and will not cause dust pollution. There is a coating called heavy-duty anti-corrosion epoxy powder coating in pipeline anti-corrosion, which can also be called fusion bonded epoxy powder. It is generally referred to as FBE abroad. It was developed as early as the 1950s and completed industrial production in the 1960s. After so many years of continuous improvement, this coating is now relatively old. Due to adhesion issues, the impregnation process of epoxy powder has never been implemented. In recent years, with the successful development of a specialized phosphating solution for epoxy powder impregnation, the adhesion problem of epoxy powder impregnation process has been initially overcome, and a new process of epoxy powder impregnation has begun to emerge. Epoxy powder coating is a new type of anti-corrosion coating that has been developed in the past 30 years.
