When procuring a water transport tanker, the tank material is paramount; 304 or 316L stainless steel is required for potable water, while carbon steel with anti-corrosion coating suffices for industrial use. Pay close attention to the tank thickness (typically 4mm to 6mm) and the presence of internal baffles (wave-breaking plates) to ensure vehicle stability during transport. Additionally, verify the pump capacity (m³/h) and the chassis brand (e.g., HOWO, ISUZU, or SHACMAN) to ensure long-term mechanical reliability and ease of maintenance.
