Pipeline anticorrosion refers to the measures to slow down or prevent the pipeline from being eroded and deteriorated under the chemical and electrochemical action of internal and external media or by the metabolic activities of microorganisms. Protection technology to protect pipelines from corrosion by soil, air and transport media (oil, natural gas, etc.).

3PE anticorrosive pipe production line, three layers of polyethylene anticorrosive coating resistance is higher, which will greatly reduce the cathodic protection system installation and maintenance costs. In the urban gas pipeline transportation, it must be through the embedded 3PE anticorrosive steel pipe into the residents' homes. However, the electrolytic weightlessness of the underground soil, pH, amount of chloride ions, amount of scattered electrons, humidity and moving friction all contribute to the corrosion of underground pipes. The corrosion rate of surface Cl- ion concentration is the average corrosion rate and local corrosion growth rate of underground materials.

The base material of 3PE anticorrosive steel pipe includes seamless steel pipe, spiral steel pipe and straight seam steel pipe. 3PE anticorrosive steel pipe can be divided into two categories: inner lining anticorrosive steel pipe and outer wall anticorrosive steel pipe. The main anticorrosive lining is cement mortar lined anticorrosive steel pipe, which is widely used and low cost. The anticorrosive steel pipe lined with cement mortar is anticorrosive with cement mortar anticorrosive layer.

3PE anticorrosive pipeline is widely used in the outer wall of 3PE anticorrosive steel pipe. Anticorrosive technology is a kind of technology that covers the inner and outer wall of steel pipe with anticorrosive layer to protect the pipe itself. Straight seam steel pipe can process spiral steel pipe and other pipes. In order to prevent casualties and property losses caused by the transportation of flammable and toxic fluids, the spiral tube mill adopts the corresponding technical standards to continuously meet the important performance operations in the process of market inspection and measurement to ensure quality and safety.
