Diameter 630 plastic-coated composite steel pipe for water supply is a new type of pipeline material, which has excellent performance and wide application prospects. This article will introduce the characteristics, production process, application fields and future development trends of this kind of pipeline from the following aspects. Plastic-coated steel pipes for water supply
1. Features. 1.Strong corrosion resistance: The surface of the plastic-coated composite steel pipe is coated with a layer of plastic film, which can effectively prevent the pipeline from being corroded by soil, water and air and other media during use, and prolong the service life of the pipeline.
2.Hygienic and non-toxic: The plastic-coated composite steel pipe is made of food-grade plastic raw materials, which will not have a negative impact on water quality and meet national health standards.
3.Reliable connection: The plastic-coated composite steel pipe adopts the hot melt connection method, which has good sealing and high reliability at the joint, and will not leak.
4.Low fluid resistance: The inner wall of the plastic-coated composite steel pipe is smooth and the water flow resistance is small, which can reduce the loss of water flow and improve the water transportation efficiency of the pipeline.
5.Good anti-aging performance: The plastic-coated composite steel pipe has been verified by the aging test and has good anti-aging performance, which can ensure the safety and stability of the pipeline during its service life.
Second, the production process.
The production process of plastic-coated composite steel pipe mainly includes the following steps:
1.Pretreatment: Cleaning, degreasing and other treatments are carried out on the steel pipe to remove oil and impurities on the surface to ensure the adhesion and stability of the coating.
2.Coating: A layer of plastic film is coated on the surface of the steel pipe, and food-grade plastic raw materials such as polyethylene and polypropylene can be selected.
3.Hot melt connection: The coated steel pipe is connected together by hot melt connection to ensure the tightness and reliability of the connection.
4.Cooling: Cooling the joints in the cooling equipment to shape them and ensure the strength of the joints.
5.Testing: Conduct pressure test, EDM test and other tests on the pipeline to ensure that the product quality meets the requirements.
Third, the field of application.
