Acid and corrosive materials demand specialized equipment built for chemical resistance, containment integrity, and regulatory compliance. Titan’s acid-service tanker trailers are engineered for the most aggressive liquid cargoes in North America, including concentrated acids, caustic solutions, and oxidizers. Every unit in our acid-service fleet meets or exceeds DOT 407 specifications with materials selected for long-term compatibility with corrosive products.

Whether you are hauling 93% sulfuric acid to a water treatment facility, moving hydrochloric acid for industrial processing, or transporting sodium hydroxide solution to a pulp mill, the barrel material, gasket compounds, and fitting alloys must be matched to the specific product and concentration. A mismatch between cargo chemistry and trailer metallurgy leads to accelerated corrosion, contamination risk, and costly failures. Titan maintains acid-service trailers configured for the products our customers actually move, not general-purpose units repurposed for corrosive duty.

Acid-service tanker trailers require barrel construction and component materials that resist chemical attack over thousands of load cycles. Standard 304 stainless steel is not sufficient for concentrated acid service. Titan’s corrosive-duty trailers are built with 316L stainless steel, which contains higher molybdenum content (2-3%) that provides significantly better resistance to pitting and crevice corrosion from chloride-bearing acids like hydrochloric acid and ferric chloride.

For highly aggressive products such as concentrated sulfuric acid above 93%, or for applications requiring absolute product purity, we offer rubber-lined barrels and PTFE (Teflon)-lined configurations. Rubber linings provide a sacrificial barrier that protects the steel shell from direct acid contact, extending barrel life and reducing the risk of pinhole corrosion. PTFE-lined trailers are specified when product contamination from metal contact is unacceptable, which is common in pharmaceutical-grade phosphoric acid and electronic-grade chemical transport.

Every component in the wetted path matters. Titan’s acid-service trailers use Hastelloy or high-nickel alloy fittings, PTFE-encapsulated gaskets, and corrosion-resistant valve seats. Outlet valves, air connections, and manway covers are all specified for the target product chemistry. This attention to the full wetted assembly, not just the barrel, is what separates a properly configured acid trailer from one that will develop leaks at fittings and gasket faces.

Titan’s acid-service trailers transport a wide range of corrosive chemicals across industrial, municipal, and agricultural markets. Sulfuric acid is the most commonly hauled corrosive product in North America, moving in concentrations from dilute (below 30%) through fuming oleum. Dilute sulfuric acid is actually more aggressive on stainless steel than concentrated grades, which is why barrel material selection must account for the specific concentration range, not just the product name.

Hydrochloric acid (also sold as muriatic acid) is particularly demanding due to its chloride content, which attacks most metals. HCl service typically requires rubber-lined barrels or high-alloy construction. Phosphoric acid is hauled in both technical-grade concentrations for industrial use and food-grade formulations for beverage production, requiring trailers that meet both DOT corrosive service and food-contact cleanliness standards. Caustic soda (sodium hydroxide) and bleach (sodium hypochlorite) round out the high-volume corrosive products, each with their own material compatibility requirements. Ferric chloride, used extensively in water and wastewater treatment, is one of the most aggressive products in regular transport, demanding dedicated trailers with enhanced corrosion protection.

Corrosive materials carry some of the highest consequence risks in liquid bulk transport. A release of concentrated acid or caustic can cause severe burns, environmental contamination, and regulatory enforcement actions that far exceed the cost of the product itself. Every Titan acid-service trailer is maintained to meet DOT 407 corrosive service certification standards, including hydrostatic testing, thickness testing, and external visual inspection on the intervals required by 49 CFR 180.

Our acid-service trailers are equipped with enhanced spill containment systems, including secondary containment around discharge valves and drip pans at connection points. Emergency shutoff valves are rated for corrosive service with materials that will not degrade or seize from chemical exposure. Titan provides material compatibility documentation with every acid-service trailer so that your drivers and loading personnel can verify that the trailer is approved for the specific product being loaded. This is a critical step that prevents cross-contamination and material incompatibility incidents.

Dedicated cleaning and decontamination procedures are followed between product changes. Acid trailers are not switched between incompatible products without proper wash-out and neutralization, because residual heel from one product can react dangerously with the next load.

Titan offers flexible leasing terms for acid and corrosive service trailers to match the way chemical operations actually run. Some customers need a dedicated fleet of acid trailers on long-term lease to serve ongoing contracts at chemical plants, water treatment facilities, or mining operations. Others need short-term capacity for a plant turnaround, a construction project requiring acid for pH adjustment, or a seasonal uptick in fertilizer-grade phosphoric acid shipments.

Our acid-service inventory is configured and ready for deployment. When you need a corrosive-rated trailer, we can match the barrel material, lining, and fitting configuration to your specific product requirements and have equipment available quickly from our 12 locations across the US and Canada.
