Factory direct sales of coated steel pipes for both internal and external use, and coated steel pipes for water supply

Description :

　　Epoxy resin composite steel pipe is a steel plastic composite product that uses steel pipe as the base pipe and plastic powder as the coating material. A plastic layer is melted and coated on the inner surface, and a plastic layer or other material anti-corrosion layer is melted and coated on the outer surface. Plastic coated steel pipes are divided into polyethylene coated steel pipes and epoxy resin coated steel pipes according to the different internal coating materials. The product marking consists of the code for the coated composite steel pipe, the code for the inner coating material, and the nominal size. Water supply lined plastic composite steel pipe is made by lining the inner wall of the steel pipe with thermoplastic pipes such as polyethylene (PE), heat-resistant polyethylene (PE-RT), cross-linked polyethylene (PE-X), polypropylene (PP-R), rigid polyvinyl chloride (PVC-U), chlorinated polyvinyl chloride (PVC-C), etc. according to the requirements of the conveying medium. Due to technological improvements, some products have added an outer plastic layer. The product is divided into plastic lined steel pipes for cold water and plastic lined steel pipes for hot water according to the temperature of the transported water. The product label consists of the code for the lined plastic steel pipe, the code for the lined plastic material, and the nominal diameter. Consumers should try to choose reputable products from large shopping malls and stores according to their actual needs when purchasing such products.

　　Inner oxygen outer polyethylene anti-corrosion steel pipes are divided into: inner fusion bonded epoxy powder outer single-layer polyethylene anti-corrosion steel pipes, inner liquid epoxy powder inner single-layer polyethylene anti-corrosion steel pipes, and inner fusion bonded epoxy powder outer three-layer structure polyethylene (3PE) anti-corrosion steel pipes. Coated steel pipes are products that use PE (modified polyethylene) for hot-dip molding or EP (epoxy resin) for internal and external coating, and have excellent corrosion resistance. At the same time, the coating itself also has good electrical insulation and will not produce electrical corrosion. Low water absorption rate, high mechanical strength, low friction coefficient, capable of achieving long-term use. It can also effectively prevent damage to plant roots and soil environmental stress. Convenient connection and easy maintenance. In order to avoid the above situation, many fire pipeline manufacturers have replaced the commonly used galvanized pipes with plastic coated steel pipes, such as coating the outer surface of the steel pipe with a layer of powder TPEP anti-corrosion steel pipe powder coating. The inner surface of the coated steel pipe is smooth, with low fluid resistance, increased flow rate, no scaling, and less likely to breed microorganisms, which can fully ensure flow rate and usage effect, and is energy-saving and environmentally friendly; In addition, the plastic coated steel pipe has excellent chemical corrosion resistance, water resistance, solubility resistance, protein resistance, and corrosion of high expansion foam extinguishing agent, which can solve the problem of water transportation.

　　The corrosion caused by burial, acid, alkali, and salt on fire protection pipelines will greatly increase their service life, which can reach more than 50 years. In addition, the powder coating used for plastic coated steel pipes does not contain organic solvents that pose a health hazard to coating production and painting personnel; And powder coating is applied in a closed system, and the sprayed powder coating can be recycled and reused, with a coating utilization rate of over 98%, which can save a large amount of limited human resources. Furthermore, most foreign building fire water supply systems use copper pipes and stainless steel pipes. Due to their high cost, copper pipes and stainless steel pipes are less commonly used in engineering practice in China. At present, domestic automatic sprinkler fire extinguishing systems generally use galvanized steel pipes or galvanized seamless steel pipes for fire water supply. However, due to the poor anti-corrosion, anti scaling, and antibacterial properties of galvanized pipes, some fire pipe manufacturing companies have started producing plastic coated fire pipes. This greatly improves the service life and reliability of the automatic sprinkler fire extinguishing system. Epoxy resin coated steel pipes are ordinary steel pipes that have undergone surface treatment.
