3. Buyer Guide: How to Liquid Choose Tanker Trailer？

When deciding between a stainless steel and aluminum tanker trailer, consider the following:

Type of Liquid: Corrosive? Food-grade? Flammable?

Budget: Aluminum is cheaper, but stainless steel lasts longer.

Payload Requirements: Aluminum allows for a higher payload.

Environmental Conditions: For humid or coastal areas, stainless steel offers better longevity.

Maintenance Capability: Stainless steel is easier to maintain but costlier to repair.

4.  How to Maintenance & Care Tips about Tanker Trailer？

To ensure the longevity and performance of your ZW Group tanker trailer:

For Stainless Steel Tanker Trailers:

Regular Cleaning: Though corrosion-resistant, regular cleaning prevents build-up of residues that could lead to pitting or crevice corrosion.   Use appropriate cleaning agents.

Inspection for Damage: Periodically check for dents, cracks, or signs of stress, especially around welds and structural points.

Valve and Seal Inspection: Ensure all valves and seals are in good working order to prevent leaks.

Rust Prevention (for minor scratches): While stainless steel resists rust, deep scratches can expose the underlying metal.   Promptly address any deep scratches.

For Aluminum Tanker Semi-Trailers:

Gentle Cleaning: Use non-abrasive cleaners to avoid scratching the surface.

Fatigue Crack Inspection: Regularly inspect for hairline cracks, especially in high-stress areas like frame connections and around manholes.   Aluminum is more prone to fatigue.

Corrosion Protection: While aluminum forms a protective oxide layer, certain chemicals or environments can still cause corrosion.   Ensure proper cleaning and avoid prolonged contact with incompatible substances.

Repair promptly: Any dents or damage should be repaired quickly to prevent further structural weakening.

For both types, adhere to the manufacturer's ZW Group recommended maintenance schedule, including tire pressure checks, brake inspections, and suspension system maintenance.
