With the development of science and technology in China and the progress of technology, China's plastic composite pipe is also developing very fast, the quality is also constantly improving, the advantages of steel skeleton plastic composite pipe in construction, chemical industry and other industries occupy the main position, steel skeleton plastic composite pipe application range is relatively wide. The advantages of steel skeleton plastic composite pipe determine the main development in the plastic pipe industry in China, the development of plastic pipe in China is relatively rapid, the quality is relatively high.
The steel skeleton plastic composite pipe is reinforced by steel skeleton, high-density polyethylene continuous matrix, low carbon steel wire distributed evenly in the annular direction of the pipe, weft wire wound and welded on the warp wire, forming a continuous mesh steel skeleton; The mesh steel skeleton is coated in polyethylene base material and formed in one time. Its pipe diameter dn50-800, its pressure 1.6-3.5mpa, both flexible, and has high strength and rigidity. There are two ways of pipe connection: electric fuse pipe connection and flange connection.
1, the inner wall is smooth and the transport resistance is small, and the anti-scaling ability is strong. When the steel skeleton plastic composite pipe is manufactured, the inner wall is smoother than the steel pipe, and the equivalent roughness is 0.08μm, and the equivalent roughness of the inner surface of the steel pipe is 0.20μm. Under the same conditions, the flow rate is more than 3 times higher than the steel pipe, and the anti-scaling ability is more than 20 times higher than the steel pipe. It is especially suitable for conveying water medium in areas with hard water quality.
2. Good wear resistance
The base material of steel skeleton plastic composite pipe is high density polyethylene (HDPE), which is specially used for pipe. The wear resistance of steel pipe is 6-7 times that of steel pipe. It has broad application prospect in medicine, petroleum and chemical industry, coal and other industries.
3. Strong corrosion resistance
Due to the use of high density polyethylene as the base material of steel frame plastic composite pipe, it has excellent corrosion resistance and good corrosion resistance to non-strong oxidizing acid, alkali and organic solvent medium.
4, both sides have the same anti-corrosion ability, the inner and outer walls of the pipeline do not need to do anti-corrosion treatment, easy to use and longer life than other pipes, especially suitable for municipal buried water supply network, ports, airports, power plants, petroleum, chemical, food and other industries.
