1. Definition & Basic Concept
- Diesel storage tank made from carbon steel that has been recovered, cleaned, inspected, and requalified for reuse.
- Combines three ideas: carbon steel construction, diesel fuel service, and recycling/refurbishment of a previously used tank.
- Not a standard international product name.
- Buyers should confirm whether it means a refurbished tank, recycled steel plate tank, or new tank marketed with recycled material claims.
2. Material & Construction Features
- Carbon steel offers good structural strength, weldability, and cost efficiency for diesel storage.
- Typical grades such as Q235B are commonly applied to diesel tanks and industrial storage vessels.
- May be single wall or double wall; designed for aboveground or underground installation.
- Underground installation requires external corrosion protection: sandblasting, epoxy coating, or fiberglass wrapping.
3. Recycling, Cleaning & Safety Requirements
- If previously storing fuel, oil, chemicals, or waste liquids, must be fully emptied, cleaned, degassed, and tested.
- Residual diesel vapors and sludge can create fire, explosion, and environmental hazards.
- Inspect for wall thickness, weld quality, corrosion, deformation, and fitting integrity.
- Tanks that cannot meet design pressure, leak tightness, or structural standards should be scrapped.
4. Procurement & Compliance Guidance
- Request design documents, material certificates, thickness inspection reports, and pressure/leak test records.
- Obtain corrosion protection details and verify compliance with local rules and fire codes.
- For international procurement, clearly specify “recycled,” “refurbished,” or “reconditioned” status.
- Avoids compliance and safety risks associated with ambiguous product descriptions.
