This lined anti-corrosion chemical semi-trailer tanker is custom-built for the transportation of corrosive chemical liquids, industrial acid-base solutions, chemical additives and the long-distance logistics delivery of hazardous chemicals. The tank body adopts a carbon steel outer shell combined with integral rotational molding lining technology, featuring a sturdy structure, reasonable dead weight, high overall strength and excellent pressure resistance, which fully complies with national road transportation regulations and standards for hazardous goods. The inner tank is integrally lined and molded in one piece without splicing seams, delivering outstanding performance in acid and alkali resistance, corrosion resistance, impermeability, scale prevention and medium pollution avoidance. The whole vehicle is rust-proof and anti-corrosive with long-lasting durability, suitable for transporting a wide range of highly corrosive chemical media. It effectively extends the service life of equipment, improves the safety and operational efficiency of chemical logistics transportation, and is widely applied to the transfer of corrosive media in chemical parks, fine chemical industry, printing and electroplating, environmental waste liquid treatment and other scenarios. It serves as safe, stable and professional transportation equipment for the chemical and hazardous goods logistics industry. Highlights: Material: High-quality carbon steel plate / optional thickened high-strength steel. Integral PE/PO anti-corrosion lining is standard for working conditions with highly corrosive media, and special anti-corrosion lining can be customized for extreme strong acid scenarios. Surface Treatment: External wall sandblasting and rust removal plus anti-corrosion primer and topcoat coating; integral high-temperature rotational molding lining treatment on the inner wall with compact and seamless structure, featuring acid, alkali and solvent resistance. Volume: Customizable in multiple standard specifications, with a common range of 30–45 cubic meters; single-compartment or multi-compartment partition design is available. Tank Structure: Horizontal cylindrical tank equipped with multiple sets of anti-corrosion and anti-surge baffles inside. Adopting fully automatic seamless welding, all tanks have passed pressure resistance, air tightness and anti-corrosion tests. Compatibility: Standard three-axle semi-trailer chassis structure with optional 50/90 traction pins, compatible with mainstream tractor brands including FAW, SINOTRUK, Dongfeng, Shaanxi Automobile and Foton. Safety Configuration: Equipped with emergency cut-off valve, static grounding device, breather valve, anti-corrosion manhole and leak-proof pipe fittings as standard, fully complying with transportation regulations for corrosive hazardous chemicals.
