We celebrate the 15th anniversary of the pilot centrifugal foundry erected by EXA INTERNATIONAL at Togliattiazot (Russia).Most of the tubes then produced are still operating satisfactorily. The usual time life of such tubes is 10 years. It shows that EXA INTERNATIONAL's proprietory foundry technology is at the top of the world standard. All the tubes of the six reforming units of Togliattiazot have been produced by the extended foundry commissionned by EXA INTERNATIONAL in 2007. More that 15000 tubes have been produced in 10 years. Togliattiazot is the first world producer of ammonia with 3 millions tons in 2016.
