Inerting is the industrial process to improve quality of welds eliminating gaseous contaminants from the weld zone and increasing the quality of the welds on pipes and tanks.
Particularly in roots, where an adequate reinforcement combined with a smooth transition between the weld and the base metal are essential to achieve the desired strength, the welds resistance to fatigue can be significantly impacted by its shape and composition.
Inerting techniques use nitrogen gas in combination with the monitoring of its oxygen (oxygen analyzers) and moisture content (dew-point meters).
Our On-Site generators VENUS are the best technical and economic solution applicable into the inerting process for the boiler-making-industry.
