1.Definition and characteristics of water supply composite plastic coated steel pipe

Water supply composite plastic coated steel pipe is a new type of pipe, which is sprayed with plastic coating on the outer layer of the steel pipe through a special process, so that the plastic and the internal steel pipe are closely combined to form a whole. This kind of pipe has many advantages, such as corrosion resistance, high temperature resistance, pressure resistance and so on. Compared with the traditional metal pipe, it effectively solves the problem of easy rust, aging, scaling, etc., which greatly extends the service life of the pipe, providing a strong guarantee for the stable operation of the water supply system.

2.the water composite plastic coated steel pipe corrosion resistance performance

(A) acid and alkali resistance

Water composite coated steel pipe in acid and alkali resistance is excellent, can adapt to a variety of acidic, alkaline media environment, such as hydrochloric acid, nitric acid, sulfuric acid and other strong acid medium is difficult to pose a threat. This is mainly due to its inner and outer layers are plastic materials, this material has excellent chemical stability and insulation. When the pipe is in contact with acids and alkalis, the plastic coating can be like a solid barrier, effectively blocking the contact between acids and alkalis and the steel pipe matrix, preventing the erosion of acids and alkalis on the steel pipe to ensure that the pipeline in the complex environment of chemical media can still maintain stable operation for a variety of industrial and civil water supply scenarios to provide reliable corrosion-resistant solutions.

(B) Abrasion resistance

In the wear resistance performance, water composite plastic coated steel pipe also has a good performance. Its surface is treated with special technology, which gives the pipe good wear-resistant characteristics. In the conveying process, whether facing the water flow may carry hard particles such as sand and gravel, or other external objects of friction, the pipe surface can effectively resist wear and tear. Moreover, due to the high smoothness of the inner steel pipe, which not only reduces the resistance inside the pipe, but also improves the conveying efficiency, so that the water flow can pass through the pipe more smoothly, reducing energy consumption, but also reducing the pipe maintenance costs and replacement frequency due to wear and tear, which provides a strong support for long-term stable water supply transmission.

(C) Aging resistance

For aging resistance, the water supply composite plastic coated steel pipe adopts non-toxic, environmentally friendly plastic coating, which has excellent antioxidant and UV resistance. When used outdoors, even if exposed to sunlight for a long time, the pipe will not appear aging. The plastic coating is able to resist the infringement of ultraviolet rays, preventing it from causing damage to the steel pipe matrix and keeping the performance of the pipe stable. This means that the water supply composite plastic coated steel pipe not only performs well in the indoor water supply system, but also in the outdoor water supply pipe laying, such as yard water supply, farm irrigation and other scenarios, can also withstand the test of the natural environment, without having to worry about pipeline rupture, leakage and other problems due to aging, which greatly prolongs the service life of the pipeline and reduces the trouble and cost of pipeline replacement.

(D) High temperature resistance

In terms of high temperature resistance, water composite plastic coated steel pipe also has significant advantages. It can be used in high temperature environments up to 95 ° C, this temperature far exceeds the traditional metal pipe tolerance range. This is mainly due to the high melting point and good thermal stability of the inner and outer plastic materials. In the hot water supply system, solar hot water system and other water supply scenarios that need to withstand higher water temperatures, the water composite plastic coated steel pipe can operate stably and will not appear due to high temperature pipeline deformation, damage and other problems. This not only ensures the normal delivery of hot water, but also avoids the safety hazards caused by piping problems, providing users with a safe and reliable high-temperature water supply solution, which meets the high standard requirements of modern society for high-temperature water supply pipes.
