NEW TREATMENT FOR THE CYLINDERS OF THE HIGH PRESSURE STAGE

NEW TREATMENT FOR THE CYLINDERS OF THE HIGH PRESSURE STAGE

19/12/2018

The steel cylinders of the last stage of the high pressure pumping units are now subjected to the new treatment.

This is a process of controlled carbon diffusion, that happens at a pressure of 5 to 9 mbar, without oxygen, at a temperature between 930° C and 1.050° C. Next step is the tempering performed in high pressure gas.

The treatment provides the cylinders of very high mechanical performances and longer duration.
