The exhaust discharge pipeline at the tank end on site has frozen. The storage tank is still being fed. The pressure in the tank increased, and the steam pipes at the public station also froze. Urgent. This post was last edited by flyyi61 on 2009-2-3 10:35.]
So what are you waiting for? Cut off the feed first
First, cut off the feed. If possible, install a heat tracing strip urgently; if that’s not possible, there is another crude method: pour hot water on it.
Rinse it immediately with boiling water – it’s cost-effective and practical; however, it’s best to install insulation at the area where freezing occurs afterward
First, the feed must be cut off, and then the discharge line should be dealt with. Note that this step is crucial; the steam pipeline cannot be handled first, as this would cause the pressure in the storage tank to continue rising. The steam pipeline should be dealt with last
First, cut off the feed flow and quickly apply temporary steam tape for preheating. Be careful not to direct the steam at the middle of the pipe section; it is important to ensure that the pressure generated after vaporization can be released promptly, as local pressure buildup can lead to accidents.
Stop feeding material, and use a temporary pipeline carrying emergency standby steam from the main heat exchange station to purge and heat the system. The second method involves using hot water, while the slowest method is electric heating.
You can at least park the car; it’s better than having an accident
Yes, park according to the parking regulations. There should be operating procedures; if not, action needs to be taken promptly. One must plan things ahead – this is a situation that’s easy to predict
