NEW Helium Tube Skid - 160,000 SCF at 3161 PSI. 40ft trailer with 34K GVWR

What is the MAWP and capacity at service pressure?

Working pressure is 3,161 PSIG with 741.6 cu ft water capacity, which the seller states yields 160,000 SCF of helium at working pressure. Test pressure is 4,742 PSIG. Tube skids are typically sized by their water volume and rated pressure; the SCF figure represents gas storage capacity using the compressibility factor for the specific gas at the stated pressure and temperature basis.

What should I inspect before putting it into service?

Verify all certification markings, data plates, and original hydrostatic test documentation are present and legible. Inspect tube bundle mounting, piping connections, valves, and pressure relief devices for shipping damage, and confirm the trailer brake system, lighting, and DOT placarding (if applicable) are complete. On tube skids, check for proper tie-down security of the tube bundle to the frame, examine all welds and fittings for damage, and ensure isolation valves cycle properly before pressurizing.
