Best Trailer Service & Repairs in Burlington, NC

A Code 406 system is designed to a higher standard. It has a manway on top suitable for interior access and inspection. It has an inversion standard it must meet. If inverted for any reason it cannot leak or loose more then a liter of fuel. The trailer is designed with some collision protection for the tank, rear and sides. There are a few other small things but that is the important stuff.

No, you do not. Double wall tanks are not required by Federal law. Local laws may vary. Double wall systems do not add any structural integrity to the system. However it does add a lot of weight and expense. In the event the inner tank were to develop a leak the outer wall would serve to contain it. A valuable benefit, but a very seldom occurrence. It would also allow you some protection from external contact to the tank should a piece of equipment strike the tank. We actually sell very few Double Wall tanks but we have them available.

Yes, trailer tanks are very special. They have to be heavy duty, they have to tolerate extreme dynamic forces from fuel surge. They should have an interior baffle to help control surge. The end heads need to be very strong and the welds have to be strong and tested. In addition the tanks have to be pressure tested. The base is reinforced to allow for the weight dynamics involved. An ordinary horizontal storage tank is not designed for transport.
