When it comes to safely transporting hazardous or non-hazardous liquids, choosing the tank shape is not an option. It is a decision based on efficiency, safety and economy. It is essential to understand why the tanker trucks that we see on our roads every day are cylindrical rather than rectangular. Have you ever wondered this? While this shape may seem advantageous in terms of theoretical capacity, cylindrical tanks have significant advantages that go far beyond this simple volumetric consideration. In this article, we will explore the technical and practical reasons that make the cylindrical shape the obvious choice for transporting liquids.
So why are liquid transport trucks designed in a cylindrical shape?
A Pressure Distribution That Ensures Safety
In fact, rectangular containers include corners and flat walls that have weak points. This point makes them fragile to deformation under pressure. Unlike this shape adopted by all tanks that offers liquids and gases a possibility to distribute themselves uniformly inside the container. On the other hand, cylinders distribute the pressure uniformly along their walls, which makes the cylinders safer for the transport of liquids.
Materials Optimization: Economy and Efficiency
On the economic side, the construction of a cylindrical tank requires less materials to build a volume equivalent to that of rectangular containers. Indeed, the curved surfaces of the cylinders reduce the surface area required for a given volume, which reduces the cost of the materials used to build the tank.
Ease of Circulation: Unhindered Liquid Flow
When unloading or loading, the liquid naturally flows downwards within a cylindrical tank. This avoids the risk of uneven accumulation in the corners of a rectangular shape. This advantage also reduces the risks related to balance during the transport operation.
Design and Adaptation: Cylinders Align with Trucks
Trucks are usually built in a long, rectangular shape, and cylinders can be made with a length that matches these trucks without compromising their efficiency or safety. In addition, the cylindrical shape allows for an even distribution of weight on the truck, this helps in maintaining better balance on the road.
Stability on the Road: Preventing Accident Risks
Tanker trucks that transport liquids must maintain their stability in motion, even when turning or stopping. Cylinders thus help to reduce the movement of liquids inside the tanker, this can improve the stability of the truck and reduce the risk of accidents.
