Manufacturer of IPN8710 anti-corrosion steel pipe for waterworks

Description :

　　The price of IPN8710 anti-corrosion steel pipes for water plants is divided into spiral seam welded and straight welded steel pipes. Spiral seam welded steel pipes are divided into automatic submerged arc welded steel pipes and high-frequency welded steel pipes. Straight welded steel pipes are further divided into ordinary straight welded steel pipes and stainless welded steel pipes. Seamless steel pipes are divided into hot-rolled pipes and cold-rolled pipes according to their manufacturing methods, and their precision is divided into two types: ordinary and advanced. IPN8710 anti-corrosion steel pipe without protective layer type without protective layer steel pipe, used to be called non galvanized steel pipe. Texture type steel pipes mainly refer to seamless stainless steel pipes and welded stainless steel pipes, which have not been widely used in outdoor large and medium-sized pipeline water supply due to cost, connection and other reasons. There are currently two types of steel pipe protective layers: metal protective layer type and non-metal protective layer type. The commonly used metal protective layer types include surface coating protective layer type and surface compression protective layer type. The common type of surface coating protective layer is galvanized pipe, which also includes cold galvanized pipe and hot-dip galvanized pipe. Hot dip galvanized pipe is still widely used due to its dense and uniform protective layer, strong adhesion, and good stability. However, due to the insufficient density and uniformity of the protective layer, as well as poor stability, cold galvanized pipes generally rust and exhibit "red water" and "black water" within a service life of less than 5 years.

　　The IPN8710 anti-corrosion steel pipe for drinking water has a serious iron smell and various harmful bacteria exceed the national drinking water quality standards. Its use has been prohibited in domestic water supply pipelines in various regions. The surface compression protection layer types are also divided into physical covering composite steel pipes and chemical blasting covering composite steel pipes according to different production processes. Among them, the physical covering composite steel pipes currently produced include steel composite stainless steel composite steel pipes and copper steel bimetallic composite steel pipes, both of which use physical methods to press heated softened thin-walled stainless steel pipes or cold thin-walled copper pipes onto the inner wall of steel based pipes through certain processes. Physical coverage composite steel pipe connections often use specialized fittings for connection. Steel pipe IPN8710 anti-corrosion steel pipe chemical blasting method covered composite steel pipe has bimetallic composite pipe. There are two main types of non-metallic protective layer: non-metallic coating type and non-metallic lining type. The "Technical Specification for Steel Plastic Composite Pipe Engineering for Building Water Supply" refers to these two types of steel pipes collectively as steel plastic composite pipes, and divides them into plastic coated welded steel pipes and plastic coated seamless steel pipes depending on the basic materials of the steel pipes attached to the steel plastic composite pipes. According to the different non-metallic materials applied, the current industry standard "Water Supply Coating Plastic Composite Steel Pipe" divides water supply coating plastic composite pipes into polyethylene steel plastic composite pipes and epoxy resin steel plastic composite pipes. Some manufacturers also produce ethylene vinyl acid copolymer steel plastic composite pipes. "Water Supply Lining Plastic Composite Steel Pipe" divides water supply lining plastic composite pipes into polyethylene, rigid polyvinyl chloride, cross-linked polyethylene, chlorinated polyvinyl chloride, and polyethylene steel plastic composite pipes. Manufacturers classify steel plastic composite pipes into three types based on their pipeline connection methods and fittings: flange type, groove type, and threaded type. According to the heat resistance of the coating, they are divided into steel plastic composite pipes for hot water and steel plastic composite pipes for ordinary or cold water use.

　　Precautions for corrosion prevention of IPN8710 drinking water pipes: 1. The product should be stored in a cool, ventilated, and dry place, isolated from sources of fire, and kept away from heat sources. 2. This product is a thick paste coating that can be applied with a thick coating to avoid sagging. After opening the bucket, it can generally be brushed without adding diluent. 3. After the coating has been stored for too long, there may be slight precipitation, and it should be stirred before use. After the coating is prepared, it should be cured for 20 minutes in summer and 1.5-2 hours in winter before application. Generally, it should be used up within 8 hours, otherwise the viscosity will thicken and it will be difficult to apply. 5. After the surface of the primer is dry, the topcoat can be applied. The interval at room temperature should not exceed two days, otherwise it will affect the interlayer bonding. The time gap between applying each layer of topcoat should also be based on surface dryness. IPN "is an abbreviation for" interpenetrating polymer networks "in English, translated as interpenetrating networks in Chinese. Interpenetrating network polymer is a new type of polymer anti-corrosion coating researched and developed in the past one or two decades. It has excellent properties of extraordinary polymer materials and is one of the hotspots in the development of polymer materials today, known as the "alloy" of polymers. The IPN series anti-corrosion coating is a type of polyurethane and poly substituted ethylene interpenetrating polymer copolymer. During the mixing and curing process of the coating, the rubber network of the former and the plastic network of the latter penetrate and firmly adhere to the surface of the coated material. Provide anti-corrosion protection and decorative effect on the surface of the material. The "IPN" series anti-corrosion coatings have excellent properties such as high strength, high toughness, abrasion resistance, aging resistance, acid alkali salt corrosion resistance, strong adhesion, resistance to hydrolysis, gasoline, kerosene and other media, non-toxic and non combustible. Therefore, it has a wide range of applications, not only for anti-corrosion of steel, but also for non-metallic components such as concrete and wood. In recent years, it has been widely used in industrial sectors such as water engineering, power plants, chemical engineering, and fertilizers, as well as in oil, gas, and water pipeline systems and civil engineering structures.
