What is a valid pressure range for compressed gas tube trailers?

• A. 100-500 psi
• B. 3-10 psi
• C. 18-40 psi
• D. 3000-5000 psi

Answer: (D)

Bulk compressed gas tube trailers carry gas at very high pressures to store a large amount in a compact space. The design relies on multiple high‑pressure cylinders bundled together, each rated for thousands of psi. This means the typical service pressure range is in the thousands of psi, commonly around 3,000 to 5,000 psi. The other options are far too low for transporting bulk gases and are associated with low‑pressure applications, not bulk gas delivery. This high-pressure range is what enables efficient loading, transport, and transfer of gas to downstream systems while maintaining safety through appropriate regulators and relief devices.
