Internally and externally coated spiral steel pipes are a new type of pipe material developed after years of research and testing. These pipes are based on spiral steel pipes, with modified epoxy resin powder applied to their inner and outer walls. The coated layer has a strong bonding force with steel, excellent corrosion resistance, drag reduction, corrosion prevention, pressure resistance, and antibacterial properties. They also offer good chemical stability and water resistance. Generally, they are not restricted by the conveyed medium, and are free from...Concerns about "running, leaking, cracking, and bursting." Widely used in fluid transportation for construction water supply, fire protection, oil, gas, chemical, sewage, mining, and agricultural irrigation, it replaces traditional materials like cast iron and steel pipes that are energy-intensive, prone to rust and scaling, have short lifespans, and are heavy to transport. Technical parameters of the coated steel pipe: Coating Material: Epoxy resin Common Color: White Coating Thickness: 200um-500um Coating Method: Internal and external spraying or external galvanized internal spraying Product Specifications: DN15-DN1200 Environmental Temperature: -30℃ to 80℃ Standard Pressure: 0.1Mpa-2.5Mpa (Note: Customization is available according to customer requirements for pipe material, wall thickness, size, and pressure resistance) Connection Methods: Threaded, socket, socket-and-socket, grooved, flanged connections, etc. Application Fields: Municipal, water supply and drainage, sewage, chemical, thermal power, reclaimed water transmission pipelines, etc. Product Features: This composite steel pipe uses thermosetting epoxy resin powder to coat the surface of the steel pipe, which is smooth and aesthetically pleasing, with the coating itself having strong corrosion and water resistance. The smooth inner wall prevents microbial growth during use, reducing the resistance of the fluid being transported.
Coating Spiral Steel Pipe (Epoxy Coated Spiral Pipe), Polyethylene coated steel pipes, etc., can effectively prevent the damage caused by plant roots and soil environmental stresses from long-term underground burial. After surface frost protection treatment, they can be used in environments as low as -30°C. Their service life is 1 to 2 times longer than that of other similar products. Steel-plastic composite pipes (such as epoxy resin coated steel pipes, polyethylene coated steel pipes, etc.) - News on the application of interior and exterior epoxy coated steel pipes comes as the Ministry of Construction issues a notice banning the use of galvanized steel pipes as water supply pipes and promoting the application of new plastic pipes. There is a wide variety of plastic water supply pipes on the market. Over the years of engineering application, plastic pipes have shown some issues and shortcomings. Due to their high linear expansion coefficient, some flexible plastic pipes are not suitable for indoor exposed installations, as they can bend and deform with temperature changes, affecting aesthetics. Their ability to withstand temperature and pressure gradually decreases with the increase of the temperature of the transmitted medium and the number of years in use. Plastic water supply pipes are not suitable for outdoor exposed installations as they are prone to UV radiation from sunlight, accelerating aging. Some large-diameter plastic pipes are neither suitable nor economical due to their material consumption and difficulty in controlling the quality of connections. The application of steel-plastic composite pipes in the water supply field has outstanding advantages.
