    It took nearly 3hrs to get washed after a load of palm oil... which solidifies as it cools. The wash worker told me that running the heat for a few hours prior to wash would save time... which makes sense to me and is easy enough to do. However, another driver told me that running heat on an empty tank can cause it to “warp”... is this true? Normal running temp is 170F, but it can get to 210F for short periods going uphill... is that hot enough to damage (warp?) a tank?

    I’m new to tanker (food grade) and eager to learn some “tricks of the trade”...

    I would't think so but i haven't worked with heated tankers much. To find out for sure give one of the tanker repair shops a call thy deal with things like this everyday. Stuart tank in Elkhorn WI. should be able to help. stuarttank.com

    look at the manufacturers plate on the side of the trailer, it will specify max operating temperature. We haul resin heated to 250+ regularly in an insulated 407ss and it doesnt warp anything.

    How hot is steam they put on the tank? 250? I know it depends on pressure

    Yes 250 is no big deal on a loaded trailer. But he is talking about heating a empty trailer to make it easier to clean. I don't think it would hurt anything but I sure never have tried it.

    True. I doubt 210 on an empty trailer will do anything. It's 135 warmer than air temp. I was just thinking that they put steam lines in a trailer. Very thick petroleum products. They didn't heat the jacket on the tank, when I carried that product.

    We preheat the trailers, the resin instantly sets up around 200-210.

    I get “steamed” carrying steric acid... needs to be delivered at 190f, and takes nearly 12 freakin hours to raise it from 170f or so- ugh.
