Curd Settling Tank is imploded during chilled water circulation 2018_update requested

Curd Settling Tank is imploded during chilled water circulation 2018_update requested

Curd Settling Tank is imploded during chilled water circulation 2018_update requested

(OP)
Referring to a 2018 thread: thread124-444189: Curd Settling Tank (Dimple Jacket) is imploded during chilled water circulation
topic starter US Rao (Mechanical)(OP)

Topic starter has not reacted anymore since 2018, would be interesting to know if the problem was indeed the insufficient vent (inbreathing) capacity.

US Rao, are you still a member?

Here's a youtube film showing what most likely happened.

(OP)
thanks Latexman, yeah I saw that too. "Funny" thing is that I encounter a similar problem, also with a curd tank.
Problem could be wrong basic tank design (wall thickness versus vent). The supplier does not make a good impression regarding design aspects, tells me "all our curd tanks are like that, so must be ok".....

regards,
Hans

RE: Curd Settling Tank is imploded during chilled water circulation 2018_update requested

Then, those two incidents provide a good economic basis to specify future curd tanks be designed, built, inspected, and stamped (certified) to an internationally recognized pressure vessel Code, and rated for "full vacuum". That's definitely a corrective action I would recommend.

From the video, it happens extremely fast. I would not size a relief device for that. I would specify the vessel be rated for full vacuum.

Good Luck,
Latexman
