Questions buyers ask
Is this ASME or DOT rated, and what does that allow me to do with it?
This vessel carries both ASME VIII Div. 1 2021 Appendix 44 certification for the inner pressure vessel and US DOT UN Portable T75 (IA-8106) approval for transport. The ASME construction qualifies it for stationary service, while the DOT portable tank approval, along with ADR/RID, IMDG, Transport Canada, and CSC certifications, allows it to be used as an ISO container for international multimodal cryogenic transport. The dual rating gives you flexibility to use it either as a fixed storage vessel or as a transport tank, though confirming your specific regulatory jurisdiction is advisable.
What is the MAWP and capacity at service pressure?
The MAWP is 249.5 psig at 50°C (17.2 bar), with a 22,000 liter water capacity. The manufacturer specifies payload capacities at various service pressures for different cryogens: 12,711 kg nitrogen at 71.7% fill, 23,526 kg oxygen at 77.0% fill, 23,526 kg argon at 76.6% fill, and 21,486 kg nitrous oxide at 79.4% fill, all starting from 0 bar initial pressure. Maximum permissible gross mass including tare is 36,000 kg with a 7,500 kg tare weight.
What is the requalification or inspection status?
The CSC next examination date is listed as 10/2027. As a new, unopened 2022 vessel, it should be current on all certifications, but ISO tank containers typically require periodic inspections at 2.5 or 5-year intervals depending on the testing scheme, and ASME vessels in stationary service follow jurisdictional inspection requirements that vary by state and service. Verify with the seller that all original test documentation, ASME U-1 forms, and DOT certification paperwork are included and confirm your jurisdiction's specific requirements.
What should I inspect before putting it into service?
Since this is listed as new and unopened, verify the vacuum integrity and insulation performance by checking the holding time against manufacturer specifications—any significant degradation suggests vacuum loss or shipping damage. Inspect all valves, pressure relief devices, and instrumentation ports for shipping damage, confirm all nameplate data matches the documentation including serial number P44797, and verify the inner SA 240 304 stainless steel tank shows no contamination if opened. For cryogenic service, proper mounting, grounding, and venting provisions are critical, and you'll need to confirm compatibility with your intended gas if switching from the manufacturer's specified service products.
