L.P. Butane,NH3 Refurbished Trailer

This is a 1967 that a friend of mine rebuilt in his shop last year. He’s also done some late 70’s and early 80’s ones. He buys used air ride slider assemblies from wrecked trailers and rebuilds these into air ride trailers. New lights, new valves, rebuild the pump, get current tests done and you basically have a trailer that’s worth we’ll over double of what you paid for it.

 

I thought after so many years you had to do the metal thickness test of tank itself? if so pay to have it done before you buy it and rebuild it?

 

Not only the thickness test (T) but also the internal visual inspection (I). You need to know what kind of shape the inside of that trailer is in before you decide whether or not to buy it.

Is there any pitting, corrosion, broken welds, or cracks?
Are the vapor and spray fill pipes securely mounted and not leaking?
Are all the baffle bolts tight and are the mounting tab welds unbroken?

 

slightly similar, Cyrogenic trailers were baffled and slop, along with poor vacuum was a sign that it was time for a rebuild, again. Interior repairs and testing and new paint and back to work. Every bucket box was re-plumbed and usually laid out differently so you had to actually follow the pipes around before opening anything to make sure it was the right valve...

 

Be sure to put fans on all open caps before you go down into tank to ck. for rust from inside if you are going to look at it before you pay the inspector to come out!!

 

These trailers still have value. It's the reason we keep refurbishing 40 year old units.
Heavier but more solidly built imho.

 

That, and the fact that it costs a ton of money to buy a new one.

 

We're told $250,000 before they get to our shop but idk.

 

Please follow confined space entry procedures before 'looking' at the interior.

 

Last year, a 10500 gal 265 psi bottle set a guy back about 180k if I remember correctly.
