- Pressure: Helium is stored under high pressure, and a large single tank would require thicker walls and a more robust structure to withstand the internal pressure. Multiple smaller tanks allow for better distribution of the gas and reduce the risk of failure or rupture in case of an accident.
- Safety in Accidents: In the event of an accident or leak, multiple smaller tanks provide better control and isolation. If one tank ruptures or leaks, the other tanks can be isolated and the gas can be safely released or transferred. This minimizes the risk of a catastrophic release of a large volume of helium.
- Loading and Unloading: Multiple smaller tanks are more convenient for loading and unloading operations. They can be individually filled or emptied, which allows for greater flexibility in handling the gas. A single large tank would require specialized equipment and procedures for loading and unloading, which can be more time-consuming and complex.
- Weight Distribution: Distributing the weight of the helium over multiple tanks helps to balance the load on the truck and improve stability during transportation. This is especially important for large quantities of helium, where the weight of a single large tank could put excessive stress on the vehicle's suspension and structure.
- Cost and Maintenance: Multiple smaller tanks can be more cost-effective to manufacture, maintain, and repair compared to a single large tank. If one tank is damaged or needs maintenance, it can be easily replaced or repaired without affecting the rest of the tanks.
- Regulations and Permits: In some jurisdictions, there may be specific regulations or permits required for transporting large quantities of compressed gas. Having multiple smaller tanks can help meet these regulations by staying within the permitted limits for each tank.
Overall, the use of several long tanks in helium transport trucks enhances safety, operational efficiency, and compliance with regulations.
