Founded in 1963, SONATRACH is now Africa’s largest company, with 154 subsidiaries, and is often referred to as Africa’s first oil “giant”.

The IMRISTEEL team has been providing services to SONATRACH since 2012 to supply seamless pipeline and anti-corrosion steel pipes.The SONATRACH delegation visited the plant in April 2015 and December 2017, respectively. The IMRISTEEL team and Baotou Steel leaders visited the SONATRACH headquarters in Algiers in September 2018.

The anti-corrosive steel pipe we supply is mainly used for natural gas transportation. The external surface of steel pipe is coated with NFA 49-710 standard 3LPE (HDPE) and the inner surface is coated with API RP 5L2 standard liquid epoxy.The advantage of the combination of these two coatings is that the 3LPE coating can extend the service life of the pipeline for 50 years, and the coating on the inner surface of the steel pipe can reduce the resistance of transportation, so as to improve the transportation efficiency.

We are maintaining good cooperation and will continue to do so.
