Baffled vs smooth bore

It would depend on what you are using the tanker for if you order it with baffles

 

MC-331

 

If my math is right -- cryogenic tanks, as well as LPG trailers....are also baffled.

Someone else correct me -- if incorrect.

I think you can get any type of tanker with baffles. A lot of chemical and food grade carriers don't get them because they're expensive to wash out. Lots of LPG and asphalt trailers have them. I actually didn't think fuel tankers had baffles cause they're compartmented

 

Fuel tankers will generally have baffles, depending on the compartment size.

 

Some 20’ isotank chemical tanks have baffles,


Some of these, not all, bulkhaul tanks had them.

 

Yep. MC 307 as well, and vacuum tankers.

I don't know about MC 312, but I would certainly hope that they're baffled considering that they haul dense liquids.

 

I remember Liquid Carbonic instructing cyro drivers to report any slop as it was a sign the baffles had come free and it would soon be time for a tank rebuild as it was usually the trailer having a hard time maintaining a good vacuum indicating it was rebuild time.

I purchased an older Heil vacuum tank that was a straight round barrel and around 1/4 of the way in from each head, on opposite sides, was a support blocking about 1/3rd of the tank circumfrence but I wouldn't consider that a baffle.

Chemical producers do not like baffles as they cannot check how clean those areas are thinking any residual = automatic contamination.

Having filtered a few rejected loads I can say contamination happens often enough WITHOUT baffles so one can understand how the shippers look at the subject.

 

Baffles are illegal for food grade.
Unless a chemical trailer is dedicated for a specific product and that product only all trailers are smooth bore. It’s way to expensive and difficult to clean a baffled tank.
