Design and Engineering of a 20 ft Flexitank

A flexitank is a specialized, flexible container designed to transport large volumes of non-hazardous liquids efficiently and safely within a standard 20-foot ISO shipping container. Constructed from high-performance synthetic materials, the flexitank maximizes cargo capacity while maintaining structural integrity during transit. These tanks are widely used for transporting water, edible oils, chemicals, wines, and industrial liquids, offering a cost-effective alternative to traditional tank containers or drums.

Mounted inside a standard intermodal container, the flexitank utilizes the existing structural framework—comprising eight vertical corner posts, top and bottom rails, side panels, and rear doors—while replacing the rigid interior with a collapsible, liquid-tight bladder. This innovative design ensures optimal space utilization and ease of handling across global logistics networks.

Core Design Features of a 20 mt Flexitank

Baffled Internal Structure

To combat the dynamic forces generated by liquid movement during transportation, modern flexitanks incorporate an engineered baffle system. These internal partitions are strategically placed within the tank to restrict lateral flow and reduce sloshing, which can cause destabilization, uneven weight distribution, or even tipping of the container on rail or truck beds.

Especially critical when transporting low-viscosity liquids such as ethanol, wine, or certain chemicals, baffles help maintain center-of-gravity stability. This enhances safety during acceleration, braking, and cornering, minimizing the risk of accidents and cargo damage.

Multi-Layer Material Construction

Flexitanks are fabricated using a multi-layer composite structure, combining materials such as linear low-density polyethylene (LLDPE), nylon, polyester, and ethylene-vinyl alcohol (EVOH) barriers. Each layer serves a specific function: structural strength, puncture resistance, chemical compatibility, and vapor barrier protection.

This layered approach ensures resistance to tearing, UV degradation, and permeation by aggressive substances. For food-grade applications, all materials comply with FDA, EU, and other international standards to guarantee product purity and safety.

Advanced Baffle System for Liquid Control

The baffle system goes beyond simple partitions—it is a precision-engineered network that manages wave dynamics and surge pressure. By segmenting the tank into controlled zones, the system dampens hydraulic shock and reduces inertial forces exerted on the container walls.

This is particularly vital for sensitive or reactive chemicals that may degrade or pose risks under agitation. The design also supports smoother filling and discharge cycles, reducing residual liquid left in the tank after unloading.

Valve and Closure Mechanism

A robust discharge valve, typically located at the bottom front of the tank, allows for complete and controlled emptying. Most systems use a 4-inch camlock or butterfly valve compatible with standard pumping equipment. The valve is protected by a durable outer sleeve to prevent damage during loading and transport.

In addition, flexitanks are equipped with a manway lid (usually 16–20 inches in diameter) for inspection, cleaning, and venting. Integrated air vents allow for pressure equalization during filling and draining, preventing vacuum formation or over-pressurization that could compromise tank integrity.

Nominal Capacity and Dimensions

A standard 20-foot flexitank is designed to fit precisely within an ISO 20' dry container (internal dimensions approximately 5.89 m × 2.35 m × 2.39 m). While physical space allows for up to ~33,000 liters, operational capacity is typically limited to 20,000–24,000 liters (20–24 metric tons) due to liquid expansion, safety margins, and regulatory requirements.

The "20 mt" designation refers to the maximum payload weight (20 metric tons), which corresponds to a volume of about 20,000 liters for water-like densities. For lighter or denser fluids, volume adjustments are necessary to stay within weight limits. Custom sizes and capacities are available for specialized needs.

Compatibility & Installation

Proper installation is critical to performance. The flexitank must be securely anchored to the container floor, with the discharge valve aligned correctly through the door opening. The container itself should be clean, dry, and free of sharp protrusions that could damage the liner.

Before filling, operators must ensure the valve is closed, the manway is sealed, and the tank is properly unfolded. Filling rates are controlled to avoid air entrapment, and overfilling is strictly prohibited. Post-discharge, the tank can be drained, rinsed, and disposed of or recycled depending on prior contents.
