Internal and external plastic coated steel pipes for sale at low prices

The plastic-coated steel pipe water supply and drainage pipes produced by Shanghai Feisu Pipe Industry not only have the strength of steel pipes, but also have the advantages of plastic pipes such as corrosion resistance, wear resistance, and low fluid resistance. They are a new type of water supply and anti-corrosion pipes. Feisu brand epoxy resin-coated steel pipe central air conditioners overcome the shortcomings of galvanized pipes, such as easy rusting, yellow water production, small pipe diameter and blockage due to accumulation, and weak strength of plastic pipes. It has significant effect on preventing secondary pollution and improving water quality. role. Refer to the implementation standards: - "Plastic-coated Composite Steel Pipe for Water Supply" B/- "Execution Standards for Hygienic Performance Indicators" Internal and external coating materials: polyethylene, heat-resistant polyethylene, cross-linked polyethylene, epoxy resin, polyurethane Shanghai Fei Plastic brand internal and external plastic coated pipe base pipes are made of ordinary hot-dip galvanized welded steel pipes (or welded pipes, spiral pipes) that are surface treated, heated and then sprayed (rolled, sucked, dipped) coated with plastic powder of various materials. Central air-conditioning plastic-coated steel pipes have the following specific properties: The tread resistance of central air-conditioning plastic-coated steel pipes ranks the highest among existing plastics, and is twice as high as nylon and polytetrafluoroethylene, and twice as high as high-density polyethylene. It is the best of carbon steel. Times, times that of stainless steel, greatly extending the service life of this tube. B. Corrosion resistance: Its chemical stability is very high, and it can withstand the effects of various corrosive media (acid, alkali, salt) and organic media (except naphthalene solvent) within a certain temperature and concentration range. Experiments show that after being immersed in various organic solvents for 3 days, there is no abnormality in its appearance and almost no changes in other physical properties. , Self-lubricating, its friction coefficient is small, self-lubricating performance is good, the resistance in the pipe is smaller than that of metal pipes, and the transportation efficiency is significantly improved. , Non-stick materials have low surface activation energy and have surface non-adhesive properties, which can effectively prevent materials (especially powdery and slurry materials) from scaling in the pipe wall. . Impact energy absorption: Its impact energy absorption value is the highest among all plastics at present, and its noise damping is very good, which effectively improves the noise in the transportation process. When changing the quality of circulating water and using chemicals to protect pipes is still not ideal, people begin to consider the material of the pipe itself. If the pipe itself is not afraid of corrosion, anti-scaling, and anti-algae, the existing problems of air-conditioning circulating water can basically be solved. . According to the National Standard of the People's Republic of China, the Construction Quality Acceptance Code for Ventilation and Air-conditioning Engineering.3. Steel-plastic composite pipes have the strength of steel pipes and the corrosion resistance of plastic pipes. They are ideal for use in air-conditioning water systems. Material. Steel-plastic composite pipes are divided into plastic-lined pipes and plastic-coated pipes. Plastic-lined pipes use steel pipes as the base, use ordinary resin to extrude the lining pipes, and then glue the pipes together. They are heated and combined with the steel pipes by using the thermal expansion of the plastic pipes. Plastic-coated pipes are made of steel pipes as the base, and are coated with polymer materials on the inner (outer) wall through processes such as powder fusion vacuum suction coating or spraying.
