I would like to ask everyone, is it okay if the torch system only has molecular seals and does not have water seals and flame arresters? Because the exhaust gas is natural gas, the temperature is very low, causing the water to freeze. Therefore, it is impossible to install a water seal, and the exhaust pressure is very low. The minimum pressure at the bottom of the torch barrel is about 10KPa. I don’t know whether the pressure drop of the torch head, cylinder body, and molecular seal can be satisfied. And is such a low pressure easy to cause tempering? Is it okay to only install a molecular seal?
I've seen it not installed, at least there is no need to install a flame arrester.
Nitrogen sealing is not very reliable. It is recommended to add flame arresters to all pipes entering the torch that may explode.
