Why Are Fuel Trucks Shaped Like A Cylinder?

[@cheeseburger3072]

I haul cryogenic liquids; liquid oxygen, argon , nitrogen and carbon dioxide. Cryogenic liquids are in a liquid form when kept at temperatures well below zero fahrenheit. At these temperatures the product creates a lot of pressure. There is a valve called a road relief valve that I crack open to help ventilate the pressure. I am a local driver and I do multi stop deliveries, after unloading my first stop the remaining liquid has room to move back and forth while I'm driving. This can be very dangerous if you aren't careful with your turns or braking actions, especially on wet or slippery pavement. Cryogenic tankers are heavily insulated, and have a plumbing system of multiple valves for loading and unloading product, also most of the trailers contain a pony motor mounted under the trailer for the unloading of product. CO 2 are slightly different, the pony motor by means of a flow valve can unload or load CO 2. My favorite product to transport is CO 2 because CO 2 is easy to unload and load. However CO 2 is usually under 300 pounds of pressure and can be very dangerous if not handled correctly. Cryogenic tankers are very expensive because of their construction. A new liquid nitrogen trailer is over $250,000 . A new liquid hydrogen trailer is over $2,000,000. Liquid hydrogen trailers are very unique. There are two layers to the tank. The outer layer is filled with liquid nitrogen ( nitrogen suffocates fire by temporarily displacing oxygen) the inner layer/tank is filled with liquid hydrogen. Liquid hydrogen can be very dangerous. When liquid hydrogen is exposed to oxygen it will ignite and combust. When it burns it will produce a very light blue almost invisible flame. This is why liquid nitrogen is in the outer shell of the trailer.

Last month here in India I saw a hydrogen carrying truck for the first time, but we use 40 or 50 individual interconnected small cylinders that are permanently mounted on truck bed instead of a single huge tank. We use the same configuration for CNG but use a huge tanker trailer for LPG. Is transporting in above mentioned way safer than a single tank?

Milk tanker driver here and also hopper trailers. Good points made in video, with milk, we can’t have any baffles at all, so all are either one big tank, or two separate tanks in on trailer. As we go from pickup farm to pickup farm, I’m the two pot we alternate which tank gets milk at which stop to try to keep the weights more even, also, the testing samples taken at each stop get batched in with the others in that particular tank, it is a real potential that one bad pickup farm can ruin several others, and can also effect the prices they are paid. Another big item is the cleaning, you have to show its last cleaning tag and milk can be rejected if not within time limits, but some will take longer and some shorter depending on what products they are making. Also, stainless steel has one huge weakness, if cleaned with too high of a concentrated chlorine, it will actually begin to rust, and fast. I’ve never seen it ruin a tanker but have seen it ruin the sampler and on one occasion the bulk tank at a farm. When the tank is just the right amount off full, all that milk moving can sometimes feel like someone hit your truck at a stop sign, there’s a lot of force there.

Many drivers struggle to transition to tankers. In many cases drivers that haul baffled tankers struggle with un baffled tankers. I hauled fuel tanker (baffled and compartmentalized) for many years and I initially struggled with un baffled tankers. It’s an art form to speed up and slow down with these tanks. Even those with experience get slammed every now and then.

[@johneverett3947]

Retired now, but used to own a gas station. In the early years under Chevron, and then independent. When ordering fuel you had to know which tank trailers were available because they had partitions within the trailer. You had to match what you wanted in terms of regular, mid grade And premium. With what tanker was available. Quite a calculation. Sometimes you had to over order one to under order another later just to fill your underground tanks. And then, of course, there was a gamble on price fluctuations. Do you over order now because the price goes up or do you lose because the price goes down? The gas business is more complicated than many understand. Such fun. 😊

[@timdouglass9831]

About 40 years ago I learned to drive a fire department tanker. Only 3,000 gallons, and it was full when we started out, so no real surge issues. Coming back with it half empty was quite a different story. Took a bit to learn how to manage all the corners, grades, and random stops in a rural mountainous fire district!

[@Moto848]

The term you want to use is surge, not sloshing. That being said, this would have been a good training video to watch several years ago when I started hauling fuel tankers.

[@filipeorr7821]

[@maxlaihc]

For casual viewers, sloshing is fine and easier to understand

[@MikeDCWeld]

​@@maxlaihcexactly what I thought. It paints a clear picture in anyone's head.

[@Bernardgrubb]

The first time I hauled hot oil for road construction I was forced through a red light due to the surge the load produced. It was an "enlightening" experience. I moved on to eventually haul double milk tankers in Upstate NY (NYS Thruway), not a lot of slowing and increasing speed as a rule but when cars did stupid stuff it was "entertaining", but more often dangerous. I don't miss driving anymore. I thought I would end up retiring from trucking but took a different path after 25 years. New position was a much easier job...

[@KevindeRegnier-e9p]

One other consideration is cost of construction. A sphere has the lowest surface area to volume ratio, meaning it takes less material to construct for the volume it can hold. But putting a sphere on a truck doesn't work all that well because when you increase the length, you also increase the height. You can only go so high and still make it under the bridge. So the next best solution is a cylinder.

[@richardbell7678]

While the round shape does even out the pressure, the main reason for the round shape is that it reduces the surface area needed to enclose a volume and less surface area means less material, which allows more of the trailer weight to be payload.

Lol as an ex milk man I know it’s called food grade stainless steel it’s a special stainless. But I haven’t ever heard of one with refrigeration built in to it they have 8 inches of foam around them then another layer of stainless around that gotta load the product under 40 and then it’s just a beat the time game.

Milk is hauled from here in south PA to Miami. They tell me it usually only gains 1 degree. Insulation and thermal mass. I've hauled fresh peanuts from Arkansas to the Norfolk area in a dry van. They were cold when I closed the doors, and two days later when I opened them they were still noticeably cold. 48,000# of cold stuff doesn't warm up quick.

cargo safety and avoid explosions is really important for tanks carrying chemical prodoucts

[@DavidHood-tx5ev]

Former gas hauler in the United States here. Diesel weighs more than gasoline, so by volume I would typically only haul 7500-7600 gallons of ulsd. If I was pulling a load of straight gas in the summer, I would usually load about 8800-8900 gallons. In the winter when the fuel is colder, it is denser. It makes a negligible difference for 10-15 gallons in your car, but makes a big difference with thousands of gallons. I might only pull 8600 gallons in the winter. One other fun fact, in a fire it isn't the liquid gasoline that burns, but rather the gasoline vapors. That is why some fuel haulers say the most dangerous part of a trip isn't when they are loaded but actually when they have unloaded and have nothing but gaseous vapors in the tank. Oh, and by volume, most fuel.tankers in North America can hold 9200-9400 gallons, but this would make them overweight in most states (except Michigan. Look up "Michigan fuel hauler" to see some massive trucks).

[@SlyNine]

Unless you're like the guy in the video dropping unleaded. He doesn't have a vapor recovery. Also diesel doesn't atomize so you're pretty safe with that.

[@GregdEntremont]

I was 16 yrs old when I took a drive in a 38 ton transport which was carrying herring from the wharf to the processing plant (this drive wasn't part of my normal job.). The tanker didn't have baffles and each time we accelerated or decelerated, the truck had a very noticeable surge. As we were driving the driver explained how important it was to not stop abruptly in front of him, and to give him room to manoeuvre at corners. Aside from a great summer job at the plant, this one-time drive was the best driver training that I ever had.

[@amynagtegaal6941]

Simplest answer: because they aren't shaped like a cube

[@baltulielkungsgunarsmiezis9714]

When youre talking about intertia youre actually talking about the free surfice effect. Fill the tank completely full and it will behave the same as a solid intertia wise. Its the slushing caused by there being free room to slush that is the problem. Casual navigator explains this a lot better, most likely because unlike trucks that will stay on land if they flip over, ships will sink if you fill the cargo holds worng.

I've been hauling milk for 15 years now. Our trailers don't have refrigation. They are stainless tanks insulated with a layer of Styrofoam. The large volume of milk is mainly what helps keep them cold. I've been told the trailers can sit in the parking lot on 100 degree day for 24 hours and only go up two degrees fahrenheit.

Haven't driven tankers but even cargo containers with bulk liquid in a bladder make sure you feel the difference hauling fluid takes. Even packaged fluid in large barrels has a noticibly affect on the handling and stopping/starting

[@jonahkolell]

As a man who took calculus 3 times and passed the 3rd time with an A. My explanation is that the efficiency for maximum volume of a shape to its surface area is the question to ask. A sphere is the maximum efficiency for volume using the least material next is pill shape where an axis is elongated. Then when considering the practicality of manufacturing and structural integrity, you get a tube that is somewhat "pill shaped" the most practical volume for material to contain the liquid.

[@gageguy]

It was my understanding that milk trailers were not refrigerated at all, because the volume of the liquid is adequate to maintain it's temperature for the short trips dairy products endure.

Can someone please clarify? Thanks

[@rodeo4-p6u]

I'm no expert but an ex fuel driver and welcome to correction I suspect the shape is for good reason 1st low center of gravity extremely important ie DG 2nd when loading it fills from bottom to top through faucet valves and vice versa unloading so ( my opinion of course ) the shape assists the unloading because the procedure is usually gravity fed .lastly although modern tankers emit tremendous static esp in transit there is a protocol to follow when unloading because the product is charged simple steps to ensure safe discharge

[@nateriget]

Been driving tankers for 14 years now, lately I’ve been driving manure trailers designed for quick loading unloading taking around 6 minutes to load and unload approximately 38.000 kg, these trailers typically only have one baffle since they are either empty or fully loaded 95-99% full, safety wise there are no issues as the trailers are equipped with automatic load capacity checks, meaning I press a button and wait once full everything shuts off and I just put the loading crane back in place. And I’m done. The only other safety issues can be cross contamination of animal illnesses so between every farm the truck has to be fully cleaned and decontaminated to insure animal health
