Double-Wall Tank Structure

Inner Tank and Outer Shell
The inner tank holds the fuel. The outer shell, made of welded carbon steel or stainless steel plates, forms an independent protective enclosure around it. Inner tank materials: Q235B, Q345, SS304, or SS316, selected per project requirements.

Leak Monitoring
The space between the two walls is monitored for leakage. If the inner tank leaks, the outer shell retains the fuel and the monitoring system triggers an alarm.

Corrosion Protection
Surface treatment includes sandblasting, anti-rust primer, an epoxy coating layer, and a polyurethane topcoat.

5° Sloped Tank Bottom Design

The tank bottom has a 5° slope that directs moisture, impurities, and sediment toward the drainage area.

Reduces residue at the tank bottom during storage

Limits the effect of contaminants on fuel quality over long-term storage

Simplifies drainage and routine cleaning

The drainage outlet arrangement and maintenance procedures are specified for each configuration.

Fuel Dispensing System & Piping Connections

Dispensing Equipment
The station can be configured with fuel nozzles, transfer hoses, flow meters, and control equipment. The pump and dispensing flow rate are matched to the required transfer rate and operating conditions.

Piping and Connections
A modular internal piping layout connects the inlets, outlets, transfer lines, and control components. Connection specifications, piping routes, and transfer methods can be adjusted to project requirements and local installation standards.

Applications

Mining Operations: Fuel supply for equipment at extraction sites and remote facilities.
Construction Projects: On-site refueling for excavators, loaders, and other machinery.
Fleet Fueling: Centralized fuel storage and dispensing for trucks, transport vehicles, and service fleets.
Agriculture: Fuel supply for tractors, harvesters, and other farm machinery.
Remote Areas: Fuel storage where permanent fueling infrastructure is not available.
Industrial Facilities: Fuel storage and dispensing for plant and site operations.
Emergency Fuel Supply: Temporary fuel supply when regular fueling is interrupted.

Quality Control

Welding Inspection: Tank welds are inspected during fabrication to assess joint quality.

Airtightness and Leak Testing: Tank sealing and containment integrity are tested.

Pre-Shipment Inspection: Equipment configuration, connections, and specified functions are checked before shipment.

Inspection Support
After order confirmation, production progress can be tracked. Pre-shipment inspection can be witnessed by video link or carried out by a third-party agency such as SGS or BV. Inspection scope, testing requirements, and documentation are agreed during order review.

FAQ

Q: What happens if the inner tank leaks?

A: The outer shell retains the leaked fuel, and the monitoring system between the walls triggers an alarm. The monitoring configuration is confirmed when the order is placed.

Q: Is the station pre-assembled before delivery?

A: Yes. The tank, equipment, piping, and wiring are installed on the skid before shipment. On site, the unit is placed on a level foundation, connected to power and transfer lines, and commissioned.

Q: What is the typical lead time?

A: Standard models typically ship within 6–8 weeks, depending on tank capacity, customization, and equipment selection.

Q: Can the tank capacity and equipment configuration be customized?

A: Yes. Tank dimensions, capacity, compartments, materials, dispensing equipment, power supply, and piping connections can be adjusted to your project.

Q: What information is needed for a quotation?

A: Please provide tank capacity, fuel type, compartment configuration, installation location, dispensing flow rate, power supply, and project specifications. Drawings and connection requirements are also helpful.

Q: What is the minimum order quantity?

A: It depends on the model and configuration. Please send your required quantity and project specifications, and it will be confirmed in the quotation.

Q: What warranty and spare parts support are provided?

A: Warranty and spare parts terms are stated in the quotation or sales contract, based on the selected equipment and order requirements.
