Gas cylinders are designed to be vacuumed. I’m not aware of any video that shows this.

Subject: [DCHAS-L] Gas Cylinder Implosion Video?

 

Hi:

 

Does anyone have a video of a compressed gas cylinder imploding due to an internal vacuum?

 

We have the tanker car implosion video and assorted videos of regulators and valves getting sheared off but haven’t been able to come up with one that illustrates that internal vacuum is bad.

 

Thanks,

Debbie
