At Zonghai Plastics, we take pride in the quality and precision of every flexitank we produce. Today, we’re taking you behind the scenes to show exactly how our 20ft flexitanks are installed inside standard shipping containers. This factory installation process ensures that every unit arrives at the customer’s loading facility ready for immediate use — no on-site assembly required.
Step-by-Step Flexitank Installation
Each flexitank installation follows a strict quality control procedure. Our trained technicians work systematically to ensure perfect fit, proper alignment, and maximum safety for liquid transportation.
1. Container Preparation
Before installing the flexitank, our team performs a thorough inspection of the container interior. We check for any sharp edges, dents, or defects that could potentially damage the flexitank during transit. The container floor is carefully cleaned and inspected to ensure a smooth surface.
2. Corrugated Board Lining
High-density corrugated paper board is applied to all interior walls and the door area of the container. This protective lining serves two critical purposes:
- Protection: Creates a smooth, protective barrier between the flexitank and container walls
- Insulation: Provides thermal insulation to help maintain product temperature during transit
3. Flexitank Placement and Securing
The flexitank is carefully unfolded and positioned at the center of the container floor. Precision alignment is critical to ensure even weight distribution and prevent shifting during transportation. Our standard 24,000L flexitank fills the entire container floor space when fully loaded, maximizing payload capacity.
4. Steel Bar Reinforcement at Doors
Galvanized steel bars are installed horizontally across the container door area to provide structural support. These bars prevent the flexitank from bulging against the doors when under pressure — an essential safety feature that prevents leaks and door damage during transit.
5. Quality Inspection and Testing
Every installed flexitank undergoes a comprehensive quality check before leaving our facility:
- Visual inspection of all seams, valves, and fittings
- Air pressure test to verify zero leakage
- Valve function test to ensure smooth operation
- Documentation check — serial numbers, certificates, and installation manuals
