Uninsulated lines or components carrying cryogenic liquids, while presenting the hazard of possible frostbite if touched, may also be so cold that it can condense the oxygen out of the surrounding air, causing a flammability and detonation hazard. 3.5 Cylinder Valves and Safety Devices The cylinder...
Close them immediately in any emergency. When on board, cylinder valves and solenoid valves shall be closed when appliances are not in use. Keep empty cylinder valves closed tightly. Keep protective covers caps or plugs in place 当小船是未看管的时,保持被关闭的圆筒阀门和电磁阀。 关闭他们立刻在...

board, he controls the solenoid valves using a Dangerous Prototypes ATX breakout board. Surprisingly the cheap Adafruit flow meter was sufficiently accurate enough to measure the amount of air in the cylinder, which, depending on the load, can be used to position the cylinder, somewhat accurately...
clean cylinder gas to the process unit. Gas is passed through the purge gas line at the highest possible rate while the system is cleaned. Close the valves 224 and 221 in this order, if the gas flow through the purge gas line must be stopped, close the valves 224 and 221 in this ...
Once a cylinder is refurbished and repaired, it must be protected by some type of coating on its exterior surfaces. The existing exterior coating (usually paint or an external multicoat system) is usually removed before repairing, replating, honing, or polishing is performed. This ensures that ...
