build Material Inspection

Start with inspecting the tank's construction material—whether it uses heavy-duty polyethylene or reinforced steel, the material should feel sturdy and free from visible flaws.

Key Points: Check for uneven surfaces, thin spots, or discoloration, which may indicate poor manufacturing or material weaknesses.

  • For steel tanks: ensure there is no signs of rust or corrosion even on hidden edges
  • For plastic tanks: confirm the material does not feel brittle or prone to cracking
  • Brittle materials could lead to leakage over time
  • Check for uniform thickness throughout the tank structure

architecture Structural Integrity

Examine the tank's structural integrity. Inspect all seams, joints, and connections—whether molded, welded, or sealed—to ensure they are smooth, tight, and free from gaps or irregularities.

  • Welded seams on steel tanks should be uniform without cracks or bubbling
  • Plastic tanks should have seamless construction where possible to avoid weak points
  • Test the tank's stability by placing it on a flat surface
  • It should sit firmly without wobbling
  • The body should not bend or deform under light pressure

security Safety Components

Check the functionality of safety and accessory components. Test the sealing of fill ports, outlet valves, and pressure relief valves by closing them tightly and ensuring no air or liquid can escape.

Testing Tip: Use a compatible pressure test tool to verify the tank maintains pressure when lightly pressurized.

  • Inspect seals and gaskets for flexibility and even alignment
  • Worn or misaligned seals are a common cause of leakage
  • If the tank includes fuel level indicators, verify accurate readings
  • Test built-in pumps for smooth operation if applicable
  • Faulty accessories can compromise usability and safety

verified Compliance & Standards

Finally, confirm compliance with industry standards. Look for certifications or labels from recognized authorities that indicate the tank meets safety and performance guidelines for fuel storage.

  • Request documentation from the manufacturer
  • Review material specifications and testing procedures
  • Check quality control processes documentation
  • Ensure the tank is designed for the intended fuel type
  • Verify suitability for expected use conditions
