    It all depends on what the product is, and what tank or liner material it is compatible with. Your shipper should let you know what kind of trailer they will accept for their product.

    Foodgrade and DEF always go in stainless steel. Petroleum products generally go in aluminum, which may or may not be lined. LPG and cryo go into thick steel.

    Aluminum, usually un-insulated, and Stainless are used in non-pressure situations. Insulated aluminum are used for bunker oil which needs to be kept warm.

    Petroleum is weight driven using aluminum to carry greater volumes as these products ae lighter than water [8.4#/gal] and are gravity discharged or pumped.

    Chlorinated solvents run twice as heavy as petroleum products and would be in a stainless trailer built to the same DOT 406 non-pressure spec as the petroleum wagon but designed for denser products.

    General chemicals run in DOT 407 insulated pressure vessels with a modest working pressure to allow unloading by air or nitrogen pressure instead of pumping.

    Acids require special trailers. Sulfuric [over 15#/gal] and similar acids in DOT412 pressure vessels with a higher working pressure than the 407 SPEC. Other acids are reactive to metal, like Hydrochloric and Ferric Chloride and were often transported in dedicated mild steel tanks with either rubber or phenolic linings. rubber was dedicated as it had to be 'pickled' to the product. Lining failure resulted in expensive repairs and/or re-barreling and re-lining...NOT CHEAP!

    Then along came FRP, Fiber reinforced plastic, the barrel made from FRP was just the ticket, didn't need to 'pickle', could be washed and backhauled, a revolution.

    We have found out with our Tankcon FRPs, bleach raises h e l l with the first lining when you switch from bleach service to say hcl or ferric chloride. Other than that, solid units. I really like the one CompTank we have. Seems to pull nicer.

    Wow! The quality and quantity of answers I received on this question far exceeded anything I expected. You guys all provided great responses and I can't tell you how appreciative I am (well, i guess I can since i just did but.....you get the saying).

    I am an owner operator hauling a dry van but I am gathering industry intelligence for other reasons related to another business I own in the logistics industry. Im afraid to say specifically what it is in case someone gets offended and reports me for spam or advertising. I want to be a part of this community so I'll refrain from posting anything else about that " other" business.

    But just so you know I am not planning on competing against other bulk liquid carriers in the market. I am in contact with many shippers who have a need to transport bulk liquid product. As of now being so fresh it's difficult to find bulk liquid drivers who are either

    A) not currently on a dedicated or regional lane
    Or
    2) has the right equipment in the right place at the right time.

    So at this time since I have load opportunities but lacking drivers Im going to do everything I can to gather knowledge on this industry so eventually i don't sound like a complete idiot when im talking to bulk liquid drivers. While also building up connections with drivers to hopefully one day assist them with any gaps they may have in acquiring back hauls or finding a reliable customer to pull from using any specifics equipment they may me using (such as an aluminum tanker!)

    Any other information is always welcome but as it stands all the contributions in this forum has answered my question with great detail and again I truly can't thank you enough.

    Be safe and keep the shiny maybe aluminum but mostly steel tanker side up

    Snapchat-654344048.jpg Usually aluminum, but FRP today.

    Maybe try leasing on with a carrier that does tankers. Learn on someone else's dime, so to speak.

    Always liked the Comp Tank units.

    I don't remember the brand but one FRP started manufacturing in Transport Provost's shops in Ville D'Anjou before moving to a stand alone home.

    That's actually a great idea. Considering my focus on tanker freight for my "other" business this could help introduce me to the field, learn the basics and meet some shippers/drivers in this field.

    Do you have any personal recommendations?

    I have 1.5 years company and 1.5 years owner op experience (3 years total). No accidents, no tickets, no oos violations. I own my truck a 2015 volvo vnl 730. I do some work on my own truck, mostly have a home shop do the work that I have a good relationship with but take really good care of the maintenance on my truck. It has 703k miles on and not one single breakdown or major repair ( except injectors when I first got the truck but the place i bought it from ended up paying for that since it happened within first week of purchase).

    I've always wanted to work in the oil fields but everywhere I look requires tanker experience and unfortunately I have none. I never had the chance to work with tanker drivers and train in my career.

    Any advice on where to start is highlt appreciated!

    Be safe driver

    Aluminum is only good to about 350f product temp, steel can go to like 500F . Think like asphalt……..

    And yes I’ve hauled a few 500F loads , and it’s pretty scary even for a seasoned asphalt guy…….

    The liner may have a lower max temp. For example, every 407-spec trailer I've ever pulled had a liner that was only good to 130°F.
