Portable Fuel Tank Quality Inspection Guide

By inspecting portable fuel tanks externally, you can quickly assess their reliability through four key aspects: material quality, structural integrity, manufacturing details, and safety markings.

1. Material & Surface

Metal Tanks: No rust/scratches, uniform thickness, intact coating

Plastic Tanks: No bubbles/cracks, crisp sound when tapped

2. Structure & Welding

Firm handles, flat base, smooth welds (no pores/tumors)

Tight hot-melt joints on plastic tanks

3. Key Components

Complete threads, tight seals, clear level window (±5% accuracy)

Unobstructed vent, undamaged breather valve

4. Labels & Certifications

Clear capacity/material markings, fuel type specified

UL/CE certifications or local compliance labels

Detailed Inspection Points

Material Quality: Metal tanks should have uniform steel thickness with no coating peeling PASS
Plastic material should be homogeneous with no surface defects PASS
Structural Integrity: Handles must withstand vigorous shaking without looseness PASS
Bases should be flat with proper anti-slip design PASS
Welding Quality: Metal welds should be smooth without porosity PASS
Plastic joints must show no delamination PASS
Component Inspection: Fuel inlet threads must engage smoothly PASS
Sealing rings should show no aging/cracking PASS

Rejection Criteria

Immediately reject tanks with: >3mm dents, visible cracks, leakage, or missing certifications FAIL

Certification Verification

Mandatory Markings: Capacity, material type, fuel compatibility, manufacturer details
International Standards: UL (US), CE (EU), CARB (California), TPED (Europe)
Compliance Check: Verify certification marks match manufacturer claims
Local Regulations: Ensure compliance with regional fuel container requirements

Maintenance and cleaning of fuel tank
Excessive sediment in the fuel tank and a large amount of impurities entering the oil pipe can accelerate the clogging of the filter and wear of precision components, affecting the normal use of the engine.
Matters regarding the placement of fuel tank
The storage location of the fuel tank must be safe to prevent fires. The fuel tank or tank should be placed separately in a visible place, appropriately far away from the diesel generator set, and smoking is strictly prohibited.
How to improve the oil storage efficiency of Portable Diesel Fuel Storage Tank
Set up a reasonable guide plate inside the portable diesel storage tank to change the flow direction of diesel when it is injected and outflowed.
fuel tank（Fuel storage device）
The fuel tank, also known as the fuel storage device, requires high corrosion resistance. At dual working pressure, it should be sealed when the gauge pressure is at least 0.03MPa.
Characteristics of Local Rapid Heating Technology for Oil Tank
The oil will not experience local high temperature or carbonization, ensuring the quality of the oil and the heat transfer efficiency of the heater.
The main types of steel oil tanks
Vertical cylindrical dome steel oil tank. The capacity is generally below 10000 cubic meters. The wall panel adopts a sleeve type connection (fillet weld).
