What is a common characteristic of compressed gas tube trailers?

Compressed gas tube trailers are specifically designed to transport high-pressure gases, and a defining feature is the way they are constructed. These trailers typically contain several individual cylinders that are securely banded together, allowing for a safe and efficient way to transport these gases. Each cylinder within the trailer is capable of holding its own pressure and is often dedicated to a specific type of gas, which enhances safety and regulatory compliance during transport.

Transporting gases in individual cylinders also helps manage the risks associated with high-pressure storage, as each cylinder can be monitored and handled separately. This design is particularly crucial for applications that require a continuous supply of gas, as it provides flexibility in distribution and use.

The other options do not accurately describe common characteristics of compressed gas tube trailers. For instance, transporting liquid ammonia usually involves different types of containers that are specifically designed for cryogenic materials rather than tube trailers. Operating pressures for these trailers often exceed the range specified, as they are typically designed to handle high-pressure environments well above 200 psi, depending on the gas being transported. Additionally, these trailers are not associated with low volume transportation; rather, they are built for significant transport capacity, maximizing the volume of gas delivered efficiently.
