Description :

　　Coated composite steel pipes have low energy consumption losses during transportation and can reduce the head of the water pump. As the head of the water pump can be converted by changing the impeller diameter, it can increase the flow rate or save energy. Steel pipes are prone to scaling and blockage; 1.3 Good hygiene performance, meeting the performance evaluation of drinking water transmission and distribution equipment and protective materials. No accumulation of dirt, no breeding of microorganisms, it belongs to a healthy and hygienic pipeline, ensuring that the fluid is not subjected to secondary pollution. Steel pipes are prone to corrosion, causing secondary pollution to the transported fluid; 1.4 Excellent mechanical strength: Coated composite steel pipes have both the mechanical strength of steel pipes and the corrosion resistance of plastic pipes. They have strong resistance to external forces such as impact, bending, pressure, and strength; 1.5 Low heat loss. Fundamentally strengthening the performance of practical applications, the level of production strength determines the final product use, among which the quality of the pipe itself, coupled with the excellent functional characteristics of high-performance anti-corrosion and insulation, are necessary quality standards. Coating a layer of plastic on the wall of a steel pipe is called a coated steel pipe, but according to the different coating layers, coated steel pipes can be divided into: internally coated steel pipes, externally galvanized internally coated steel pipes, and internally and externally coated steel pipes. Internally and externally coated steel pipes are also a type of coated steel pipe. Once the cable coated steel pipe is marketed, it is greatly welcomed by the market. Quickly replacing various pipelines, including galvanized pipes, stainless steel pipes, as well as copper pipes, threaded pipes, etc., the use of pipelines has gradually expanded and received warm praise from people. Compared with previous pipelines, this is exactly what galvanized pipes could not do in the past. Our company's galvanized steel pipes are not our main products. In addition to external galvanized lined plastic steel pipes (cold water type), we also provide corresponding PP-S internal and external coated composite steel pipes.

　　The main factor of plastic coated steel pipes is pre-treatment. The pre-treatment of plastic coated steel pipes is usually: pipe mouth grinding, cleaning, acid washing or (internal sandblasting, external sandblasting). Therefore, most manufacturers now use sandblasting to polish the pipe wall, making the pipe wall rough. The rough surface is conducive to the adhesion between plastic and steel pipes. After these steps. Heat the steel pipe again to coat the inside of the pipe wall with plastic, and then heat it up again. Spray nano epoxy powder on the outside of the pipe wall. After the internal and external spraying is completed, heat it up for the third time to solidify the powder, and then cool it down. This completes the processing of an inner and outer coated steel pipe. Water coated steel pipes have been widely used in petroleum. Internally and externally coated composite steel pipes are mainly divided into two types: internally coated steel pipes and internally and externally coated steel pipes. The coating materials are generally epoxy resin and polyethylene, and can also be customized according to customer requirements. The processing technology of fire protection coated pipe fittings is divided into four types: hot-dip molding, high-pressure static spraying, rotational molding, and encapsulation. Moreover, the processing procedures vary depending on the connection method. The raw materials required for this product are plastic powder and steel pipes. At the beginning of the entire processing, raw materials need to be purchased. The plastic powder commonly used for firefighting is epoxy resin, and the steel pipe models used are seamless steel pipes, straight seam steel pipes, or spiral pipes. After the raw materials are purchased, they need to be inspected, especially the steel pipe model, length, and wall thickness need to be measured. Next, cut the steel pipe into the required length specifications, and polish and deburr the ends of the pipe. If the required pipeline connection is a groove, it is necessary to use a groove rolling machine to press the groove. The width and depth of the groove should be installed according to CJ/T156 standard, and attention should be paid to the flatness of the pipe end face when pressing the groove.

　　The size and length of the coated steel pipe section in the warm water aging test are about 100mm. Corresponding anti-corrosion treatment should be carried out at both ends of the pipe section. The pipe section should be soaked in distilled water at (702) ℃ for 30 days. After the test, it should be taken out and naturally cooled to room temperature to check the internal coating of the specimen. The test results should comply with the provisions of 5.15. The application scope of hot-dip plastic steel pipe: hot-dip plastic steel pipe is used as a protective pipe for urban power and communication cables when buried underground. Construction of transportation road and bridge engineering, engineering construction; When cables are buried directly in driving lanes or pass through traffic crossings, protective pipes should be used for industrial parks and residential construction projects; This product can be used in conjunction with various accessories and can be assembled according to different engineering requirements; The main performance of hot-dip plastic steel pipes as protective pipes for special situations such as cable crossing bridges and rivers. It is mainly used in the drainage of gas and residential areas, as well as the transportation of water. The plastic coated composite steel pipe has characteristics that general steel pipes do not have, mainly including corrosion resistance, wear resistance, etc. Its service life and various excellent functions are even more outstanding compared to ordinary steel pipes. Internally and externally coated steel pipes are widely used in the construction industry for water supply and drainage systems, HVAC circulating water systems, petroleum and chemical pipelines, automatic sprinkler systems, and natural gas. Plastic coated composite steel pipes are based on welded steel pipes, and sandblasted chemical steel plastic composite pipes are made using processes such as dual pretreatment, preheating, internal and external coating, curing, and post-treatment. It has excellent comprehensive performance, strong corrosion resistance and mechanical properties, good chemical stability and water resistance, as well as functions such as drag reduction, anti-corrosion, compression resistance, and antibacterial. It is usually not limited by the transmission medium, and the plastic coating has strong adhesion with steel.

　　The inner surface of the inner and outer plastic coated steel pipes is coated with plastic, which can maintain the smoothness of the pipeline, the resistance of water flow, and the flow rate of water. In addition, due to the smooth flow of water, the flow rate of water can be guaranteed. At the same time, there will be no scaling or breeding inside the pipeline during use, which will not pollute the water quality. Secondly, the outer surface of the inner and outer plastic coated steel pipes is coated with plastic. It can provide excellent protection against objects and liquids passing through the interior, and because the coating raw material used inside the inner and outer plastic coated composite steel pipes is improved anti-corrosion epoxy resin powder, it can achieve excellent chemical corrosion prevention effect, so that the product will not have adverse consequences such as blockage or leakage due to corrosion or scaling during long-term use. Therefore, this also makes the inner and outer plastic coated composite steel pipes more widely used in China's fire protection industry, which can extend the service life of China's fire pipes. Internally and externally coated anti-corrosion steel pipes have hygiene and anti-corrosion properties, are non-toxic, odorless, rust free, and have no secondary pollution to water quality. They can also resist the erosion of acid, alkali, salt, and untreated sewage, and have the super strong deformation resistance of steel pipes. They are a pipe material with excellent comprehensive performance. Internally and externally coated anti-corrosion steel pipes are a new type of pipe made of welded steel pipes or seamless steel pipes as the matrix, and the inner and outer walls are composed of materials such as hot-melt bonded epoxy powder and linear low-density polyethylene powder.
