Lingyuan cable internal and external plastic coated steel pipe steel wholesale base Let's take a look at the load displacement, load time, displacement time, stress-strain load (2) point extension diagram facilities related to the quality of three PE corrosion prevention in China. China has issued and released an external ring cooling device for steel pipes, which has improved the cooling effect, but if so, it fundamentally threatens the quality defects caused by * * * external cooling facilities and the thickness reduction of weld bead coating. Among them, the rebar 1610 contract opened at 2092 yuan, *2189 yuan, *2090 yuan, and closed at 2170 yuan, up 90 yuan/ton from the settlement price of the previous trading day. With the development of economy and technology, pipeline internal corrosion prevention has been gradually put on the agenda and has been paid attention to by people. It also has good corrosion resistance and impact resistance at low temperature, and PE has low water absorption (less than 0.01%). Many people only know one thing about the use of 3PE anti-corrosion steel pipe, and they don't know the other. Its function is really wide coverage. It is suitable for underground water supply and drainage, underground shotcreting, positive and negative pressure ventilation, pumping, fire sprinkler and other pipes in coal mines. The anti-corrosion technology of PE anti-corrosion steel pipe greatly reduces the cost. The service life of plastic coated steel pipe is more than 50 years. The powder coating of plastic coated steel pipe is added with flame retardant and modified with epoxy resin powder. The coating has superior temperature resistance and will not burn or soften in long-term use. Rust proof coating needs to meet special performance: rust proof, weak adhesion, non-toxic, sprayable, good corrosion resistance, etc. In addition, the conventional plastic coated steel pipe is burned at low temperature, and the electrodynamic powder has been sprayed to complete the good adhesion of the coating to the inner wall of the steel pipe. The fire-fighting plastic coated steel pipes are used in the plant fire-fighting system, office building fire-fighting system and shopping mall fire-fighting system, mainly to avoid the shortcomings of galvanized fire-fighting steel pipes, such as short service life, serious pollution and easy rust
the anti-corrosion steel pipes in Lingyuan cable steel wholesale base are mainly used for the internal and external anti-corrosion of buried and underwater steel pipes, cast iron pipes and concrete pipes. They are also suitable for the anti-corrosion, waterproof and seepage prevention of chemical plant plants and all kinds of steel structures, wharves, ships, sluices, oil refining and chemical equipment, and concrete structures. Epoxy coal tar pitch anticorrosive coating is thick paste type. The coating film composed of epoxy resin, coal tar pitch, pigments, additives and solvents has excellent adhesion, impact resistance and water resistance; This product can be used as the anti-corrosion finish for the outer wall of seawater or fresh water pipelines, the outer wall of underground oil pipelines, the outer wall of heat pipelines and sluice gates, but it can also be used as the anti-corrosion finish for sewage treatment tanks, water storage tanks, coal mine shaft derricks, etc., which should be applied to the outer wall of pipelines. Replace the commonly used galvanized pipe with fire-fighting plastic coated steel pipe. The internal surface of the fire-fighting plastic coated steel pipe is smooth, the fluid resistance is small, the flow is increased, and there is no scaling, it is not easy to breed microorganisms, which can fully ensure the flow and use effect, energy conservation and environmental protection; Moreover, the plastic coated steel pipe has excellent chemical corrosion resistance, water resistance, solubility resistance, protein resistance, and high expansion foam fire extinguishing agent corrosion, which can solve the corrosion of fire pipelines due to water transmission, burial, acid, alkali, and salt, and will greatly improve the service life of fire pipelines, with a service life of more than 50 years. The protection of the outer metal pipe is much more difficult
the relevant person in charge of the Ministry of environmental protection of Lingyuan cable steel pipe and steel wholesale base said on the 14th that from February 15 to March 15, the Ministry of environmental protection will work with relevant provinces to Beijing Tianjin Hebei and 18 surrounding cities to carry out special supervision on air quality in 2017. In addition, the 2017 work plan for the prevention and control of air pollution in Beijing, Tianjin, Hebei and surrounding areas is soliciting opinions from Beijing, Tianjin and other places, and the control measures are very strong. For example, it is required that in the winter heating season of 2017, the production of steel in relevant cities will be limited by 50%, and that of electrolytic aluminum plants by more than 30%. The purpose of this measure is to alleviate the situation that AQI (air quality index) index explodes in the top cities. The steel industry will bear the brunt, and the intensity of production restriction will be increased, which is conducive to the steady rise of steel prices. The outer surface of the embedded plastic coated steel pipe with inner reinforcement adopts three layers of anti-corrosion measures: * the layer is galvanized, and the steel pipe forms a cathode to protect against rust. The second layer: epoxy primer, which forms a dense polymer protective film on the surface of the galvanized layer to isolate it from air and water, reduces the oxidation and corrosion of the zinc layer during the new materials exhibition held in Ningbo, which has a deep industrial foundation, so as to improve the service life of pipes. The third layer: topcoat, which strengthens the protective effect of the film and improves the beauty of the product. When used underground, appropriate anti-corrosion measures shall be taken to improve the service life of the system; It can also be used in the series of "embedded double-sided plastic coated steel pipe with inner reinforcement" (PE pipe + carbon steel pipe + PP pipe) with plastic coated steel pipe as the base pipe and a layer of plastic pipe on the outer surface. Look at the national market
Lingyuan cable steel wholesale base for internal and external plastic coated steel pipes. This product is a new type of pipe material developed in China. It adopts a composite structure with plastic coated protective layers inside and outside, and the middle is reinforced welded steel pipe or seamless pressure bearing steel pipe, which overcomes the defects of easy rust, corrosion, high pollution, low strength and easy deformation of plastic pipe, and integrates the common advantages of steel pipe and plastic products, It is an environmental protection product promoted and used by the state. Plastic coated composite steel pipe is a steel plastic composite pipe material composed of a layer of polyethylene (PE) resin, ethylene acrylic acid copolymer (EAA), epoxy (EP) powder, non-toxic polypropylene (PP) or non-toxic polyvinyl chloride (PVC) and other organic substances with a thickness of 0.5 ~ 1.0mm dissolved in the inner wall of the steel pipe. It not only has the advantages of high strength, easy connection, water impact resistance of the steel pipe, but also overcomes the problems that the steel pipe is prone to corrosion, pollution Scaling, low strength of plastic pipes, poor fire performance and other shortcomings, and the design life can reach 50 years. The main disadvantage is that bending is not allowed during installation. In recent years, the anti-corrosion measures of urban buried long-distance pipelines often achieve the anti-corrosion effect by isolating the pipeline from the atmospheric environment. The commonly used powder coating technology for pipeline protection mainly includes electrostatic spraying and roller coating technology. With the continuous development of economy, the search for more socially beneficial anti-corrosion measures has been constantly explored. Roll coating process and external 3PE anti-corrosion design are adopted to realize high utilization rate, simplification and standardization of roll coating epoxy powder, and finally achieve better internal and external anti-corrosion effect. Qufu fire-fighting plastic coated anti-corrosion steel pipe manufacturer is perfect for mining plastic coated steel pipes. Taking the steel pipe as the base pipe, the outer wall is coated with thermosetting powder paint with high adhesion, impact resistance, corrosion resistance and weather resistance, and the inner wall is coated with thermoplastic powder paint with high adhesion, corrosion resistance and food grade sanitation
