Buried three-layer PE coated anticorrosive spiral steel pipe is a high-quality pipeline material, which is widely used in various buried pipeline projects due to its excellent corrosion resistance and long service life. This kind of steel pipe adopts advanced production technology and technology, and three layers of PE anti-corrosion coating are coated on the surface of the steel pipe, which can effectively prevent the pipe from being corroded by soil, water and air and other media.
The production process of buried three-layer PE coated anticorrosive spiral steel pipe mainly includes the following steps: firstly, the surface pretreatment of the steel pipe is carried out to remove impurities such as dirt, rust and grease on the surface of the steel pipe; Secondly, a layer of epoxy powder is coated on the surface of the steel pipe, which is a material with good adhesion and corrosion resistance; Thirdly, a layer of PE anti-corrosion layer is applied to the epoxy powder to enhance the corrosion resistance of the pipeline; Finally, the pipe is fused at a high temperature to make the coating tightly bonded to the steel pipe.
The characteristics of buried three-layer PE coated anticorrosive spiral steel pipe are as follows:
1.Strong corrosion resistance: The three-layer PE anti-corrosion coating can effectively prevent the corrosive effect of soil, water and air on the steel pipe, and prolong the service life of the pipeline.
2.Reliable connection: The pipeline adopts hot melt connection technology, which can ensure that there is no leakage at the connection, and avoid the problems of poor connection and poor sealing that may occur in traditional connection methods.
3.Convenient construction: The pipeline is light in weight, easy to handle, and does not have high requirements for construction machinery, which can effectively reduce the difficulty and cost of construction.
4.Good environmental performance: the pipeline is made of environmentally friendly materials, which are non-toxic and tasteless, and will not cause pollution to the environment.
5.Long service life: Due to the excellent corrosion resistance and long service life of the pipeline, it can reduce the frequency of repair and replacement, and reduce the operating cost.
In all kinds of buried pipeline projects, buried three-layer PE-coated anticorrosive spiral steel pipes have a wide range of application prospects. For example, in urban water supply and drainage projects, it can be used as an alternative material for water pipes and drainage pipes; In oil and gas transportation engineering, it can be used as an anti-corrosion material for oil and gas pipelines; In chemical pipeline engineering, it can be used as a transportation pipeline for corrosive media such as acid, alkali and salt; In farmland irrigation projects, it can be used as irrigation water pipes, etc.
In short, as a high-quality pipeline material, the buried three-layer PE-coated anticorrosive spiral steel pipe has a wide range of application prospects and important social significance. Its emergence provides a more reliable, environmentally friendly and economical choice for all kinds of buried pipeline projects, and helps to promote the development and progress of pipeline engineering in China.
