Anti-corrosion steel pipe is a pipe material that prevents corrosion of steel pipes and prolongs the service life of steel pipes. Since the steel pipe works in a humid, humid, salt spray and corrosive environment for a long time, it is easy to cause corrosion on the surface and interior of the steel, resulting in a decline in the performance of the steel pipe. Therefore, anti-corrosion steel pipes came into being.

Project Challenge
The National Oil and Gas Company of Algeria was established in 1963 to manage the country's oil industry. At the beginning of 1997, the company's oil reserves were 1.25 billion tons and natural gas reserves were 3.6 trillion cubic meters. Algeria is one of the world's largest natural gas exporters and the second largest natural gas supplier in the EU. In 2021, Algeria's natural gas exports will reach 55 billion cubic meters, 80% of which will go to Europe. According to IEA statistics, in the first half of this year, Algeria exported 4.577 billion cubic meters of natural gas to Spain, a year-on-year increase of more than 38%.
Our Solution
This time the outer coating adopts the anti-corrosion standard of NFA 49-710. The purpose of using the outer anti-corrosion layer is to increase the service life of the steel pipe anti-corrosion layer several times for the buried pipeline. Pipes of the same material may be as long as a few years. Leakage occurs, and some of them have been buried underground for decades without corrosion, because they have adopted an external anti-corrosion layer. Therefore, the use of anti-corrosion coating is very important to increase the service life of the pipeline.
