Vertical liquid oxygen dewar bottles and high-quality low-temperature gas bottles should be judged from the production process. Before leaving the factory, they need to undergo ultrasonic flaw detection, helium mass spectrometer leak detector and other layer by layer detection to ensure the quality of the products leaving the factory. High-vacuum multi-layer winding technology ensures better thermal insulation of products. We can provide 80-1000L products. In terms of pressure, we can provide 1.37MPa-3.45MPa. Customers can choose according to their own needs.
