Pulling and squeezing – it should be vacuum, right?
API 2000 4.4.1.5 In the case of viscous oils, such as cutback and penetration-grade asphalts, where the risk of tank collapse due to stuck pallets or clogged flame arresters is greater than the likelihood of flames spreading into the tank, open vents may be used as an exception to the requirements of Sections 4.4.1.2 and 4.4.1.3 regarding PV valves or flame-arresting devices. 4.4.1.5 When storing viscous oils (such as diluted asphalt or asphalts with a certain penetration grade), and when the risk of tank collapse caused by stuck valve discs or blocked flame arresters is greater than the chance of flames entering the tank, open vents can be employed as an exception to the requirements outlined in Sections 4.4.1.2 and 4.4.1.3 concerning breather valves or flame arresters.

““Choubi” should be equivalent to “suck in” or “deflate”, right? Besides collapse, it is also called the shrunken phenomenon or concavity; Handshake corrected my wrong spelling, thanks Echo. This post was last edited by lihx_susan on 2009-4-15 at 16:14
Implosion of storage tanks (inward collapse). Example sentence: The implosion of tank **** occurred while the discharge pumps *** were transferring liquid out of the tank, and unfortunately the breather valve was blocked.
After all this fuss, it’s deflated. That must be a deformity.

I thought that \"collapse\" meant a top-down breakdown, while \"vacuum\" emphasizes the mechanism involved; implosion, on the other hand, refers to rapid and intense destruction from the outside in.
