Acid / Alkali Corrosive Liquid Tank Semi-Trailer
The Acid / Alkali Corrosive Liquid Tank Semi-Trailer is a specialized, heavy-duty transport trailer engineered specifically for the safe and compliant hauling of highly corrosive hazardous chemicals, including concentrated mineral acids (hydrochloric acid, sulfuric acid, phosphoric acid) and caustic alkali solutions (sodium hydroxide). Built with a high-strength carbon steel structural outer shell integrated with a seamless, rotation-molded polyethylene (PE) or polypropylene (PP) interior plastic lining, it provides superior chemical resistance and prevents structural corrosion. Equipped with chemical-grade PTFE/PP-lined internal discharge valves, specialized pressure-vacuum relief vents, and spill containment troughs, it ensures absolute containment integrity under aggressive chemical operating conditions. Paired with 3 heavy-duty commercial axles, adjustable air or mechanical suspension, and dual-line WABCO ABS/EBS pneumatic braking, it delivers exceptional chemical safety, structural longevity, and road stability. Fully certified under ADR, ISO9001, CCC, CE, DOT, and SGS standards.

Key Structural & Performance Features
1. Seamless Rotomolded Plastic Lining & Dual-Layer Shell Architecture
- Advanced PE/PP Inner Lining: Equipped with a heavy, seamless rotation-molded polyethylene (PE) or polypropylene (PP) plastic lining thermally fused or mechanically locked to the inner carbon steel shell, offering complete immunity against mineral acids and caustic alkalis.
- Structural Outer Shell: Fabricated from high-strength Q345B carbon steel, providing robust mechanical load-bearing capability to absorb highway driving forces while protecting the interior corrosion barrier.
- Anti-Surge Baffling Architecture: Internal coated baffles reduce fluid momentum during transit, engineered with specialized flow ports to maintain uniform lining integrity across all compartments.
2. Acid-Resistant Valving & Spill Containment
- PTFE / PP-Lined Discharge Assembly: All wetted components, including internal foot valves, bottom discharge pipes, and ball valves, are lined or manufactured from chemically inert materials (PTFE, PVDF, or PP) to prevent metal-acid reactions.
- Corrosion-Resistant Venting: Outfitted with specialized acid-resistant pressure-vacuum relief valves to prevent over-pressurization during transport and vacuum collapse during liquid unloading.
- Top Spill Containment Troughs: Integrated catch basins around the manhole covers capture accidental drips or chemical residue during loading operations, protecting the chassis exterior.
3. Robust Chassis Integration & Anti-Corrosion Protection
- Acid-Resistant Exterior Coating: The entire exterior carbon steel chassis and tank shell undergo abrasive sandblasting followed by multiple coats of acid-resistant epoxy primers and chemical-grade polyurethane topcoats.
- WABCO ABS/EBS Pneumatic Braking: Dual-line air braking system paired with WABCO ABS and emergency relay valves, ensuring synchronized, dependable stopping power under heavy chemical loads.
- Hazardous Grounding Protocols: Features anti-static grounding reels, copper grounding straps, and spark-free accessories to comply with international hazardous chemical transport regulations.
Commercial & Logistics Terms
- Warranty Policy: 3-Year warranty for the carbon steel shell and internal plastic lining; 1-Year warranty for axles, valves, and running gear.
- Delivery Lead Time: 35 – 40 working days upon order confirmation and engineering drawing approval.
- Packaging & Shipping: Nude packing; shipped via Bulk Cargo vessel or Ro-Ro vessel.
