Used CNG Storage 3-Packs – 23′ rated to 5500 psi with good PRDs

You are looking at CPIndustries ASME used CNG storage vessels rated at 5,500 PSI MAWP. This is a 24-feet long 3-pack which has been the most commonly used in high volume CNG fueling station development. This 3-packs CNG tube was retired as a part of the fully operational CNG Stations around  June 15th, 2020, and does not have any physical or cosmetic damage. All of the bottles are in great shape and show minimal wear (small rust spots). They can be easily restored to their original condition by treating a few rusty spots and applying a couple of layers of 2-stage epoxy paint.

All cylinders are gas freed and were nitrogen purged per NG and AGA purge procedures around 6/25/20). They both are ready for transportation and have been verified CNG free. Dimensions: 23′ L X 20″ D X 9’ W X 5’ H, approximately 11,000 CU/FT per vessel @ 4,500 PSI.

All of the Pressure Reduction Valves (PRDs) on those used CNG storage vessels have been installed or recertified in 2019 so they will be good until the next recertification in 2022.

The seamless steel pressure vessels for stationary ground storage applications are designed and constructed in accordance with the ASME (American Society of Mechanical Engineers) Boiler and Pressure Vessel Code for unfired pressure vessels, Section VIII, Division 1 (including Appendix 22), Division 2 and Division 3. The majority of the U.S. States have laws requiring the use of pressure vessels designed to the ASME Code for stationary storage applications.

Those used CNG storage vessels have no damage, just normal wear and tear due to weather exposure (small rust spots). With an approximate life-span of 295 years, those CNG vessels still have plenty of life left in them.

We have two (2) 3-packs available at this time. Both of the CNG vessel packs can be sold together or separately.

The used CNG vessels are sold AS-IS. There are no PRD’s on these vessels as they were removed and retained by the original owner. We can outfit them vessels with appropriate size and pressure PRDs (new or used) for an extra charge. For a small fee, ASME vessels can be covered with a brand new layer of protective coating giving them a refreshed look.

The used CNG vessels are located in Dallas, TX and ready to be shipped ASAP. We can do all required shipping arrangements within the continental USA or worldwide out of the port of Houston, TX for your convenience. We can also provide required cut sheets, brochures, and any support information to the buyer per request.

Sale Price: $42,500 per 3-Pack.
