Double Wall Tank Skid Station
Double-Walled Storage Tank Design Features
Our double-walled storage tanks feature an "inner tank + outer protective shell" structure:
The inner tank (primary tank) directly stores the fuel, bears the weight of the fuel, and maintains the required operating pressure. Materials can be customized according to requirements, such as Q235B/Q345 carbon steel or SS304/SS316 stainless steel.
The outer protective shell is constructed from carbon steel or stainless steel plates - cut and welded to form an independent protective structure - and undergoes anti-corrosion treatment and seal testing to ensure long-term durability and reliability.
| Anti-corrosion treatment processes | Sandblasting for rust removal (to enhance coating adhesion) Anti-rust primer Epoxy coating / Polyurethane topcoat Multi-layer anti-corrosion protection |
| Seal testing | Airtightness test Leak test Weld inspection |

5° Sloped Tank Bottom Design
The 5° sloped design directs moisture, impurities, and sediments toward the drainage area, minimizing the impact of contaminants and deposits on fuel quality during long-term storage.
Design advantages:
Facilitates natural settling of impurities
Simplifies drainage and maintenance
Reduces residue at the tank bottom
Enhances fuel storage reliability
Extends equipment service life
Integrated Fuel Dispensing System
The double-walled tank skid station can be configured with a complete fuel dispensing system tailored to customer needs, including components such as fuel nozzles, transfer hoses, flow meters, and control equipment. An optimized system layout ensures convenient operation while guaranteeing stable and reliable fuel transfer.
Internal Fuel Piping and Connection System
The unit utilizes a modular internal fuel piping design, logically arranging inlets, outlets, transfer piping, and associated control components. Customization is available based on project requirements-including connection specifications, piping layout, number of fuel compartments, and transfer methods-to meet installation and operational standards across different countries and application environments.

FAQ
Q: How does the leak detection work?
A: The gap (interstitial space) between the two walls is monitored. If the primary tank leaks, the liquid is captured by the outer wall, and our monitoring system triggers an immediate alarm.
Q: Is the skid station truly ready to operate upon delivery?
A: Yes, that's the main advantage. The unit is pre-assembled, pre-piped, and pre-wired. You primarily need to place it on a level foundation, connect it to power and your transfer lines, and it's essentially ready to go.
Q: How long does it usually take to deliver a double wall tank skid station?
A: Lead time varies based on customization and size, but standard models typically ship within 6-8 weeks. We provide a firm timeline upon order confirmation.
Q: Can you help with custom specifications for my chemical?
A: Absolutely. We specialize in customizing these stations. Just tell us the chemical, concentration, temperature, and capacity, and we'll engineer a solution with the right materials and accessories.
