What material is a fuel tanker trailer made of?

Aluminum and stainless steel are what’s they’re built with.
Non sparking metals.
Hose fittings and connector fittings are pot metal and brass. Again, non sparing metals.

 

But you can drop a match in them to check to see if there empty.

 

O like the tankers that are plastic with the new vapor release button on the nozzle, self lighting fuel level indicator.

 

...once.

 

You sure can.
Enjoy your express lane trip to Jupiter while you’re at it.
If you’re lucky, you meet Jesus on the way!

 

No luck to meeting Jesus, it will not be accidental.

 

Correct.
It’ll be Darwin, assisted by the trailer trash lady at Walmart, leaving her car running while smoking Marlboros pumping $3.86 of gas into her crapbox express with one headlight and smashed door held on with duct tape.

 

FCMSA's hazardous area has published 'specifications' for all HM trailers divided into different 'SPECS' for various products to be transported under their authorization.

The SPECS are updated as technology and materials improve and the 'authorized' trailer spec can change, often with the older spec remaining in use until aged out of use.

Incorrect use usually has semi-disastrous results.

Caustic Soda [Sodium Hydroxide] eats aluminum.

Yes the 'story' has some truth, Quadrel Bros. had an aluminum wagon loaded in San Juan and dropped at the pier and the next morning there wasn't much left.

At Matlack we missed one sub note requiring a lining to use a stainless steel trailer and the product ate it's way out.

On the other hand the introduction of FRP trailers made lined trailers backhaul-able as it was washable where rubber linings were 'pickled' to one product and always came home empty.

Fuel loading is specialized and separated from anything else so contamination by something corrosive to the tank is near impossible.

Biggest danger is 'harry the driving hat' driving over your hoses.

 

But what they ask pertained to fuel trailers, which are normally aluminum. Sometime lined.
