Introduction to 3PE anti-corrosion steel pipe

Description :

　　The so-called 3PE anti-corrosion steel pipe is actually a three-layer anti-corrosion steel pipe. In recent years, the use of anti-corrosion steel pipes in various industries such as construction has gradually expanded, which is closely related to people's lives. We also hope that those who are not familiar with this industry can have a process of popularizing theoretical knowledge, and we hope to provide a good platform for more people who want to learn about anti-corrosion steel pipes through our articles.

　　Product features of anti-corrosion steel pipes:

　　1. Long service life

　　Polyethylene pipe has good molecular weight, stability and aging resistance. Under normal operating temperature and pressure, the service life can be guaranteed to exceed 50 years.

　　2. Corrosion resistance

　　Polyethylene molecular structure has high stability and is resistant to chemical corrosion from natural gas, liquefied gas, artificial gas, etc. It does not require secondary anti-corrosion equipment, and chemical substances in soil have no degradation effect on pipelines.

　　3. Flexible polyethylene pipe is a type of high toughness pipe with a fracture elongation of over 500%. The flexibility of polyethylene pipe makes it easy to bend, and in engineering, it can bypass obstacles by changing the direction of the pipeline. In many cases, the flexibility of the pipeline can reduce the number of pipe components used and lower installation costs.

　　4. Excellent impact and seismic resistance

　　The low-temperature brittleness temperature of polyethylene is very low, and it can be safely used within the temperature range of -60 ℃~60 ℃. It has strong adaptability to uneven settlement of pipeline base. During winter construction, due to the excellent impact resistance of the materials, pipeline cracks will not occur.

　　5. Good wear resistance

　　The test results show that the wear resistance of polyethylene pipes is four times that of steel pipes, especially in the field of mud transportation, where the wear resistance of polyethylene pipes is better than that of steel pipes.

　　6. The inner surface of polyethylene pipes with low flow resistance is smooth, and the Manning's coefficient is 0.009. The smooth inner surface and non adhesive properties ensure that polyethylene pipes have higher transport capacity than traditional pipes, while also reducing pressure loss and water consumption of the pipes.

　　7. Protecting the environment

　　Polyethylene pipes are processed without the addition of heavy metal stabilizers. This material is non-toxic and harmless, making it a green and environmentally friendly pipeline material. The polyethylene material itself can be recycled and reused without polluting the environment.

　　8. Good flame retardant and anti-static properties

　　Flame retardant and anti-static polyethylene pipes are suitable for specific places such as flammable and explosive environments.

　　9. Safe and reliable connection methods

　　Polyethylene pipes are mainly connected by hot solution or electric melting, which essentially maintains the consistency of the interface material, structure, and pipe body, realizes the combination of joints and pipelines, effectively resists the circumferential stress and axial tensile stress caused by internal pressure, and does not have to worry about leakage and air leakage.

　　10. Lightweight, easy to operate, and simple in structure

　　Polyethylene pipes have a specific gravity of only 1/8 of steel pipes, are easy to carry and bend, have simple and fast welding processes, low overall costs, and significant economic benefits.
