The electric ball valve at the bottom of the naphtha storage tank has frozen
Thread Content
Hello everyone. Due to the continuous drop in temperatures in the northern region recently, the electric ball valve at the bottom of one static tank in my storage area – which contains naphtha – has frozen and cannot be opened. This system lacks insulation as well as heat tracing, and there is no steam system in the vicinity. Power supply of 220/380 volts is available at the fire dike surrounding the tank cluster. I would appreciate any suggestions for a solution. Thank you!
Thank you! We also plan to use this solution!
If the valve is important, temperature measurement points can also be added to the electric heat tracing.
The maintenance team will arrive tomorrow to handle it together, thank you!
In some places, electric heating can be used
1. Strengthen tank dehydration. 2. It is generally half oil and half water; by using the steam condensate (hot water) available nearby, the valve core can usually be opened.
Today, steam was temporarily supplied from a distance of 100 meters, and the issue has been resolved. Thank you all!
