(3T) I-Beam tube skid

What is the MAWP and capacity at service pressure?

The MAWP is 5,500 PSIG with a total capacity of 187 CU FT. The listing does not state whether this is water capacity or gas capacity at rated pressure, so confirm with the seller whether the 187 CU FT is at 5,500 PSIG or a different reference condition.

What is the requalification or inspection status?

The unit is listed as unused from 2023, but the listing does not indicate whether initial hydrostatic testing or certification has been completed. For ASME vessels, an initial inspection and data report should have been issued at fabrication; for DOT cylinders, the hydrostatic test date and next due date should be stamped on each tube. Request documentation showing current certification status.

What should I inspect before putting it into service?

Since this is an unused unit, verify that all pressure relief devices are within their test dates and set correctly for your service, confirm all valves operate smoothly and seat properly, and check that interconnecting piping and fittings show no shipping damage or thread galling. Inspect the skid frame and tie-down points for any impact damage during transport, and confirm the nameplate data matches your application requirements for gas type and flow.
