Reasons for the popularity of Dewar flasks

The advantages of using Dewar flasks are: low pressure, transportable, and safe to use. Large gas storage capacity greatly reduces transportation and labor costs. The pressure vessel is made of stainless steel, the bottle body is clean, and the gas purity is high. The gas cylinder has low temperature and can be used in connection with the gas phase and the liquid phase. The gas storage capacity of a 185-liter Dewar is equivalent to 18 15MPa 40-liter compressed gas cylinders. Dewar can provide users with a completely independent gas and liquid supply system, suitable for various industries such as handicraft industry, medical treatment, laboratory, etc. (such as gas phase, liquid phase, welding, hospital oxygen supply station, aquatic oxygen supply system, etc.).

Safety performance
　　1. The stainless steel support and low temperature glass fiber reinforced plastic support structure between the inner and outer tanks of the gas cylinder is sturdy and durable;
　　2. The stainless steel neck tube can withstand accidental Dewar sideover;
　　 3. The adsorption material can maintain the vacuum for a long time;
　　4. The pressure vessel is equipped with an inner liner bursting disc, double protection of the inner liner safety (patent design);
　　 5. Equipped with shell relief device to protect the shell safety;
　　6. ​​Anti-vibration bottom ring design, anti-skid and shock absorption, prolong the service life of Dewar; Gas use steps
　　1. Install a suitable pressure reducer on the joint of the gas valve for the Dewar;
　　2. Connect a suitable gas pipeline between the gas equipment and the pressure reducer;
　　 3. Open the booster valve of the gas cylinder;
　　4. By observing the pressure gauge, it can be increased to the set value of the economic pressure regulator;
　　 5. Open the gas cylinder valve;
　　6. ​​Adjust the pressure reducer of the pressure vessel to a suitable gas pressure;
　　7 After the gas is used, close all the Dewar valves
