Polyethylene anti-corrosion spiral steel pipe is a kind of pipe widely used in pipeline anti-corrosion, its manufacturing process is unique, excellent anti-corrosion performance, long service life, is widely used in petroleum, chemical, electric power, water conservancy and other fields of pipeline anti-corrosion. Among them, the buried three-layer polyethylene anti-corrosion spiral steel pipe is a high-quality anti-corrosion pipe, which has better anti-corrosion performance and higher strength, and can meet the more demanding pipeline use environment.
1. The structure of buried three-layer polyethylene anticorrosive spiral steel pipe.
The buried three-layer polyethylene anti-corrosion spiral steel pipe is composed of an inner pipe, an intermediate binder and an outer polyethylene anti-corrosion layer. The inner pipe is made of high-quality seamless steel pipe or welded steel pipe, which has been treated by rust removal, inner wall coating and anti-corrosion coating, etc., which improves the corrosion resistance of the pipeline. The intermediate binder is made of high-viscosity epoxy resin, which has good adhesion and corrosion resistance, and can firmly bond the inner tube and the outer polyethylene anti-corrosion layer together to form a whole. The outer polyethylene anti-corrosion layer is made of high-density polyethylene, which has good impact resistance, wear resistance and corrosion resistance, which can effectively protect the pipeline from the erosion of soil, water and chemicals.
2. The advantages of buried three-layer polyethylene anticorrosive spiral steel pipe.
1.Excellent anti-corrosion performance: The polyethylene anti-corrosion layer of the buried three-layer polyethylene anti-corrosion spiral steel pipe has good chemical stability and electrical insulation properties, which can effectively prevent the erosion of the pipeline by the corrosive medium and ensure the service life of the pipeline.
2.High strength and high stiffness: The buried three-layer polyethylene anti-corrosion spiral steel pipe uses high-quality seamless steel pipe or welded steel pipe as the inner pipe, which has high strength and rigidity, and can withstand large pressure and bending stress.
3.Reliable connection: The buried three-layer polyethylene anti-corrosion spiral steel pipe is connected by heat shrinkable sleeve or electric fusion sleeve, which can ensure the tightness and connection strength of the pipeline and prevent the occurrence of accidents such as leakage and bursting.
4.Simple construction: The anti-corrosion layer of the buried three-layer polyethylene anti-corrosion spiral steel pipe does not need additional protection measures, and can be directly buried underground, which is simple and fast to construct. At the same time, the weight of the pipeline is lighter, which makes it easy to transport and install.
5.Environmental protection: The anti-corrosion layer of the buried three-layer polyethylene anti-corrosion spiral steel pipe will not pollute the soil and water source, and meets the requirements of environmental protection.
3. The application range of buried three-layer polyethylene anticorrosive spiral steel pipe.
Buried three-layer polyethylene anti-corrosion spiral steel pipes are widely used in the anti-corrosion of liquid and gas transmission pipelines in petroleum, chemical, electric power, water conservancy and other fields. Due to its excellent anti-corrosion performance and high strength, it is widely used in long-distance transmission pipelines, deep buried underground pipelines, pipelines across rivers and valleys, and other scenarios. At the same time, due to its advantages of simple construction and environmental protection, it is also widely used in urban water supply pipe networks, sewage treatment plants, landfills and other municipal engineering fields.
In short, as a high-quality anti-corrosion pipe, the buried three-layer polyethylene anti-corrosion spiral steel pipe has the advantages of excellent anti-corrosion performance, high strength, easy construction and environmental protection. It is widely used in the anti-corrosion of liquid and gas transmission pipelines in various fields, and plays an important role in ensuring the safe operation of pipelines. With the continuous development of science and technology, the application prospect of buried three-layer polyethylene anticorrosive spiral steel pipe will be broader.
