The Concept and Corrosion Resistance of Coating Steel Pipe

Coating steel pipe, the product is the latest development of a new type of pipeline materials, both inside and outside are coated protective layer, the middle of the enhanced welded steel pipe or seamless steel pipe composite structure, belonging to the country to promote the use of environmentally friendly products.
First, good corrosion resistance: combined in the steel-plastic composite pipe wall of polyethylene, polypropylene, PVC and other materials is a health and safety, performance and stability of plastic materials, materials do not contain toxic substances. The material in the steel pipe wall, not rust, no scaling, smooth wall, and not aging. Japan's experience shows that in the absence of external corrosion, the life of steel-plastic composite pipe can reach the service life of the building. At the same time, with the matching malleable iron pipe used on the inner surface of an injection molding process, lining a plastic protective layer, pipe and lined steel pipe connected to ensure that the tube end from corrosion, thus solving the past galvanized pipe as a water pipe When the resulting turbidity and red rust problems.
Second, the superior mechanical properties: inside and outside the coating steel pipe is welded steel pipe, so it has excellent mechanical properties, high pressure, impact resistance, coated or lined with plastic pipe can still withstand a certain range of bending The In addition, its linear expansion coefficient is small, easy to deformation after installation. The plastic pipe although corrosion-resistant, but the linear expansion coefficient, easy to bend, easy to deformation after installation. It must be installed according to the standard expansion joints or take other measures to compensate for the expansion, or in the course of the use of thermal expansion and contraction caused by the pipe and pipe between the cracks and leakage.
