Welding Oxygen Production Plant
In the fields of metal fabrication and heavy manufacturing, the quality and efficiency of welding processes depend directly on the purity and stable supply of the oxygen used. Leveraging our technical expertise in cryogenic air separation, Shenger Gas Welding oxygen production plant, designed specifically for the welding industry, is more than just equipment-it is a stable, efficient, and economical on-site oxygen generation solution. We understand that welding-grade oxygen demands extremely high purity to ensure weld quality, while production continuity and energy consumption control are also core concerns for our clients. Therefore, our plant is engineered to guarantee the smooth and reliable operation of your production line from the source.
Core Technology Principle: Cryogenic Distillation, The Source of Purity
Our Welding oxygen production plant is based on proven and reliable cryogenic air separation technology. The core principle involves introducing strictly filtered compressed air, purified of moisture, carbon dioxide, and hydrocarbons via a molecular sieve system, into an efficient heat exchanger where it is cooled to extremely low temperatures before entering the distillation column system. Inside the column, precise fractional liquefaction and distillation occur by utilizing the different boiling points of air components (oxygen boiling point: -183°C, nitrogen boiling point: -196°C), thereby continuously separating a high-purity oxygen product. The entire process is automatically monitored by an advanced Distributed Control System (DCS), ensuring product purity and system safety.
