LNG horizontal tank sand filling and vacuuming
Thread Content
Can any hero recommend a construction team for sand filling and vacuuming of LNG horizontal tanks? Thank you.
What is the difference between cinnabar jars and wrapped jars?
Just contact the storage tank manufacturer to send someone.
I want to know too. Please explain to the teacher. In addition, the vacuum degree of the pearlescent sand cannot be maintained, and the inside is filled with sand. If the can is wrapped, how to deal with it?
The thermal insulation structures are different. Pearlescent sand relies on pearlescent sand for thermal insulation. High vacuum relies on aluminum foil paper or aluminum-coated film. The reflective insulation properties are very different. High vacuum has better performance than pearlescent sand!
There are many reasons why the vacuum cannot be maintained. If it rebounds quickly after being pulled out, you need to check for leaks and test to see if there is leakage in the inner and outer containers. If there is no problem, consider whether the pearlescent sand itself contains excessive water, and the internal and external containers are not clean enough, etc.!

I don’t understand. Is there any difficulty in filling it with pearlescent sand? Also, isn't vacuuming done with a vacuum pump?
