DEFINITION
What is a self-bunded fuel tank?
Double-wall / integrally bunded above-ground steel tank: primary inside an outer shell (the bund), one-piece ship and lift. Built to order in Zhangjiagang for mining, construction, power, fleet and remote sites.
Also calledDouble-wall · Integrally bunded
ContainmentIntegral outer steel shell
Typical fuelsDiesel · Petrol · Jet-A · DEF
Site typeAbove-ground
COMPARISON
Self-bunded vs external bund vs single-wall
Three common layouts below. Extra civil containment — confirm local rules before ordering.
| Layout | How containment works | When it is used |
|---|---|---|
| Self-bunded (double-wall) | Outer steel shell is built with the tank; ships as one unit. | Sites that need transportable secondary containment without a separate civil pit. |
| External bund | Concrete wall or pit built around a tank on site. | Fixed installations where civil works are already planned. |
| Single-wall | Primary vessel only — no integral outer shell. | Only where local rules and the project design accept separate containment. |
CAPACITY
Safe Fill vs gross volume
Gross ≠ Safe Fill. Gross = inner geometric capacity. Safe Fill = working fill for ops / quotes. Say which figure the RFQ needs.
Full guide: Safe Fill capacity and how to size a self-bunded tank — definitions, a worked sizing method, and the RFQ checklist.
| Term | Meaning | How to specify |
|---|---|---|
| Gross / nominal volume | Full geometric capacity of the primary tank. | Use when comparing shell size or nameplate geometry. |
| Safe Fill | Agreed working fill for day-to-day use (below gross). | Use for operations, pump sizing and commercial quotes. |
COMMON FOOTPRINTS
~20 ft / HC and ~40 ft / HC class tanks
Common container-like classes:
- ~20 ft / high-cube class (~38 kL class) — Compact project storage where a shorter footprint fits the yard or camp layout. Exact litres depend on wall thickness, baffles and fittings — confirm on the drawing.
- ~40 ft / high-cube class (~68 kL class) — Flagship above-ground self-bunded storage for larger sites. When a front equipment room is fitted for pumps, filters, meters or a dispenser, that compartment reduces usable tank volume versus a tank-only shell of the same outer length. Do not assume full-cube volume if dispensing equipment is required. Specs for the ~40 ft / HC / ~68 kL class: 40ft / 68KL self-bunded fuel tank.
20ft / ~38kL class RFQ — same family as 40ft / 68KL. Layout class only; Safe Fill needs an order drawing. WhatsApp 20ft RFQ · Email 20ft RFQ
Cube · about 1–5 KL — same double-wall idea, compact. Portable: containerized fuel stations. Pump-integrated: integrated dispensing tanks.
ENGINEERED TO THE PROJECT
Common self-bunded tank configurations
- Compact to high-capacity — From service tanks and fleet support units to 68 KL and 130 KL project storage.
- Project-specific connections — Filling, venting, suction, return and dispensing connections arranged to the site specification.
- Protected equipment areas — Lockable service compartments can house pumps, filters, meters, controls and monitoring equipment.
- Project documentation — drawings, inspection records and data sheets can be supplied for the order; the document set is confirmed before production.

APPLICATIONS
Designed around operating conditions, not a fixed catalogue only.
Construction and infrastructure
Fuel storage for civil works, built so the tank can be transported, set down and later relocated.
Power generation
Day tanks and bulk storage for diesel generators. Filling, vent, suction and return follow the generator layout.
Fleet and equipment depots
Yard storage for trucks and equipment. A lockable compartment can house the pump, filter, meter and controls.
Oilfield and remote projects
Storage where a separate civil bund is not practical. The outer shell is fabricated with the tank.

Safe fill is not gross volume. Safe fill and gross tank volume are different. The 200–130,000 L figures on this page describe the product family, not a promise that safe fill equals gross volume. Quotations are based on the safe fill you need. Containerized PFS stations follow the same rule. No price list is published here, and any capacity figure is illustrative until it is confirmed in writing for your order.
FAQ
Common Questions
Are you a factory or a trading company?
Manufacturer. HQ / primary plant: Zhangjiagang Zhongbao; second base: Henan Zhongbao (Yongcheng).
What project documentation can you supply?
Drawings, inspection records, data sheets — scope confirmed in writing before production.
What information do you need for a quote?
Fuel, capacity, dispense / monitor needs, destination, size or transport limits.
What is a self-bunded fuel tank?
Above-ground steel tank with integral outer bund (double-wall). Local rules may still need extra containment.
How is this different from an external bund?
External bund = site wall/pit. Here the shell is built with the tank — one unit.
Which fuels can it store?
Diesel, petrol, aviation kerosene, AdBlue / DEF — steel / coatings follow the order fuel.
What should I send for an RFQ?
Please provide in writing: fuel type; required capacity and whether the number is Safe Fill or gross volume; pump / dispenser / metering needs (and whether a front equipment room is required); destination country and any dimensional or transport constraints; and the certification or document scope you need listed on the order. Certification lists are not the same as certificates already held for a given destination — we confirm scope in writing before production.
Does a front equipment room change capacity?
Yes. On ~40 ft / ~68 kL class units, a front equipment room for pumps or a dispenser uses length that would otherwise be tank volume. Tell us if dispensing equipment is required so we quote the correct Safe Fill / gross figures — do not assume full-cube volume with a dispenser.
Where are the tanks manufactured?
Export engineering and primary manufacture from Zhangjiagang, China. Docs / inspection scope before production.
