Spiral steel pipe is a steel widely used in transportation pipelines, which has excellent anti-corrosion properties and structural strength. The cold wrap anti-corrosion spiral steel pipe is based on the spiral steel pipe, and the cold wrap anti-corrosion process is adopted, so that it has stronger anti-corrosion performance and longer service life.
1. The structure of the cold-wound anticorrosive spiral steel pipe.
The structure of cold wrap anti-corrosion spiral steel pipe includes steel pipe, anti-corrosion layer and protective layer. Among them, the steel pipe is the foundation of the whole pipeline, which is made of high-quality steel and has high strength and stiffness. The anti-corrosion layer is an important part of the pipeline, and the anti-corrosion treatment by means of cold wrapping can effectively isolate the surface of the steel pipe from the external environment and prevent the steel pipe from being corroded. The protective layer is the outermost layer of the pipeline, which is made of polymer materials, which can further protect the anti-corrosion layer and prolong the service life of the pipeline.
2. Advantages of cold-wound anti-corrosion spiral steel pipe.
1.Strong anti-corrosion performance.
The anti-corrosion layer of the cold-wound anti-corrosion spiral steel pipe is made of polymer material, which has good isolation performance and anti-aging performance, which can effectively prevent the steel pipe from being corroded. At the same time, the protective layer can further protect the anti-corrosion layer and improve the anti-corrosion performance of the pipeline.
2.Convenient construction.
The construction of cold wrap anti-corrosion spiral steel pipe is very convenient, and it is only necessary to wrap the cold wrap tape on the surface of the steel pipe in a certain way. Compared with the traditional hot-dip galvanizing anti-corrosion process, the cold-wrapped anti-corrosion process does not require complex steps such as heating and cooling, and the construction period is shorter and the efficiency is higher.
3.Long service life.
Due to the excellent anti-corrosion performance and structural strength of cold wrap tape anti-corrosion spiral steel pipe, its service life is longer than that of traditional steel pipes. According to statistics, its service life can reach more than 50 years, reducing the cost and trouble of replacing pipelines.
4.Environmental protection and energy saving.
The manufacturing process of cold-wound tape anticorrosive spiral steel pipe does not need to be heated, cooled and other steps, which is more environmentally friendly and energy-saving than the traditional hot-dip galvanizing process. At the same time, due to its long service life, it can also reduce the pollution to the environment and the waste of energy when replacing the pipeline.
3. Application range of cold-wound anticorrosive spiral steel pipe 1In the field of city gas, city gas is one of the important infrastructures of modern cities, and the safe and stable operation of gas pipelines is directly related to the quality of life of citizens and the economic development of cities. The cold-wound anti-corrosion spiral steel pipe has excellent anti-corrosion performance and structural strength, which can effectively ensure the safe and stable operation of gas pipelines. 2.Petrochemical industryThe petrochemical industry is one of the important pillar industries of the national economy, and a large number of pipelines are used in the storage and transportation of petrochemical products. Cold wrap anti-corrosion spiral steel pipe can effectively prevent the pipeline from being corroded and ensure the safe and stable transportation of petrochemical products. 3.Construction engineering fieldThe construction engineering field is one of the important application fields of steel pipes, and the anti-corrosion performance of steel pipes is directly related to the safety and service life of buildings. Cold wrap tape anti-corrosion spiral steel pipe has excellent anti-corrosion performance and structural strength, which can effectively ensure the safety and service life of the building.
