1. The structure and characteristics of three-layer polyethylene anticorrosive spiral steel pipe.
The three-layer structure polyethylene anticorrosive spiral steel pipe is composed of three parts: the inner layer, the middle layer and the outer layer. The inner layer is a specially treated steel pipe, which has good corrosion resistance and anti-rust function;The middle layer is a polyethylene anti-corrosion layer, which has excellent chemical resistance and insulation properties;The outer layer is a polyethylene protective layer with high abrasion and impact resistance.
The characteristics of the three-layer structure polyethylene anticorrosive spiral steel pipe are as follows:
1.Excellent corrosion resistance: The middle layer of the three-layer polyethylene anti-corrosion spiral steel pipe can effectively resist the corrosion of various chemicals, such as acid, alkali, salt, etc., and can maintain the finish and cleanliness of the inner wall of the pipe for a long time.
2.High strength and high wear resistance: The three-layer structure polyethylene anti-corrosion spiral steel pipe has high strength and wear resistance, can withstand large pressure and friction, and is not easy to deform and damage.
3.Long life and low maintenance: The three-layer polyethylene anticorrosive spiral steel pipe has a long service life, generally more than 50 years, and does not need to be frequently repaired and replaced, reducing the operating cost.
4.Environmental protection and safety: The material of the three-layer polyethylene anti-corrosion spiral steel pipe is non-toxic and tasteless, environmentally friendly, will not produce harmful substances, and meets the requirements of environmental protection. At the same time, the pipeline material also meets various safety standards to ensure the safe operation of the pipeline system.
5.Easy installation: The connection method of three-layer structure polyethylene anti-corrosion spiral steel pipe is simple and reliable, which can be welded, flanged and other methods, and the installation speed is fast, and no special tools and equipment are required.
The application field of polyethylene anti-corrosion spiral steel pipe with two- and three-layer structure.
