Operation of cryogenic air separation equipment

Liquid air separation plant solutions Most liquid air separation plant cold energy receiving stations have a peaking role, their use is generally for domestic gas or car refuelling, with high and intermittent periods of gas consumption, for example 1-2 hour peaks in the morning and midnight. If the liquid air separation plant vapourisation plant is intermittent, the plant will not operate continuously. The solution is based on the intermittent use of liquid air separation plant and is character...

(1) argon arc welder must have a pressure vessel welder qualification certificate, no permit personnel are strictly prohibited to weld. (2) in order to effectively control the speed of heating of the welded parts, should be used as far as possible to break the arc method of welding, welding wire diameter selected towel 3mm, while welding current should be given strict control, such as towel 12 * 2 instrumentation pipe joints recommended to use 60 ~ 80 amps welding current, the maximum should no...
