Question: This question relates to box tanks and removable linings. “Have you ever heard of installing a flexible lining in a tank container? I can think of reasons why this isn’t a particularly good idea. I’ve also been asked recently why box tanks, like those made years ago by Hoyer and Hugonnet, couldn’t carry more cargo than a standard liquid tank.”
Tank Guru: I have indeed heard of installing a disposable liner inside of a tank container, but never seen it done. One company I know tried it several years ago and ultimately determined that it wasn’t an effective solution, either because of installation difficulties or cost-effectiveness. The reasons to install would be either to protect the tank from the cargo in the case of chemicals corrosive to stainless steel, or to protect the cargo from the tank such as shipping edibles as a backhaul in a chemical tank.
Box tanks were limited in capacity because most of the older 20′ boxes had a MGW of only 24000 KG to begin with, and additionally there is no point carrying a load larger than you could legally transport over the road without being overweight.
