Smooth Bore Question

With what we call a "tight fill" tank, the surge will be noticeable, but not overwhelming. If you were putting 5300 gal in a 7000, that's another story. You really need to figure out what your dry weight is, then you'll know what you can load. I have yet to meet anyone pulling tanks who couldn't load 45,000 and still be under 80k. Assuming you can actually load 46,000, that would put you at 5,515 gal and with a tight fill, it would ride nice. As everyone said above me, take it slow and steady down the hill and you'll be fine.

 

Kari Kool made good trailers. if it is insulated, the steel support where the top and belly wrappers meet can rust away. also the subframes are steel; if the outlet opening gets 'tight' to the bumper they are rusted out.

most carriers switched to stainless subframes for this reason.

 

just take it easy around curves..

 

The frame rails parallel to that cross member and hidden by the wrappers can rust in the same fashion and the tank will start to crush them, hence my warning about the outlet getting close to the bumper.

make sure that the person who plates the cross-member knows his stuff and uses a thick material. A full load won't slop but will put maximum loading on those frame rails...

If this is a 'Spec' trailer [the serial number plate will have that listed] any repairs that include welding onto the barrel requires an ASME shop with a R or U stamp to maintain specification.

 

If the mfg serial number plate doesn't say MC Spec 303 or 306, etc. it was a non-spec trailer, not specified for haz mats. don't worry about it. even a spec trailer built back then wouldn't always have a U stamp unless it was a higher pressure vessel.

 

5300 gallons in a 5700 gallon trailer is not going to be bad at all your feel it moving around a bit but nothing like 5300 gallons in a 9000 gallon tanker.

my very first ever load in a smooth bore tank was exactly that around 5500 gallons in a 9000 gallon smooth bore tanker at max gross weight. i thought i got rear ended pulling out onto the highway.
