Super Capacity ASME Storage Tanks

Custom Fabricated Large Diameter Storage Tanks Built to Your Specifications

Super Capacity Storage Tanks - Fabrication


TransTech is your source for custom designed and fabricated super capacity ASME pressure vessels for the high volume storage of natural gas liquids (NGL) and liquefied petroleum gas (LPG), including propane, butane and related hydrocarbons

Backed by decades of experience serving global corporations in upstream, midstream and downstream markets, our expert design and fabrication teams can readily produce super capacity bullets to your exact specifications with storage volumes of up to 120,000 gallons or more.

We offer comprehensive services to address every aspect of your project and simplify the acquisition process – one point of contact, one invoice.

Super capacity pressure vessels for both aboveground and underground applications are designed, manufactured, tested, delivered and installed—within the shortest lead times you'll find. 

Every storage vessel we produce is fabricated to the highest standards to provide you with unmatched quality and safe, reliable performance.  And all vessels are guaranteed to meet all ASME Division 1, Section VIII standards.

We bring state-of-the-art manufacturing processes and tools to every project we deliver and our modern, 160,000 square feet fabrication facility gives you access to one of the largest, most advanced pressure vessel manufacturing facilities in the United States.


Together with one of the largest inventories of new and used storage vessels in the country—offered through our parent company, TransTech Energy—we’re able to provide a wide range of options for addressing your storage vessel needs, and extraordinary flexibility in meeting your project budget and schedule demands.

All finished storage vessels are tested and ASME certified, National Board code stamped and registered.


For large volume storage needs, another option to consider is the use of modular, skid mounted storage vessels. Available for smaller size vessels of up to 60,000 gallons, multiple skid-mounted vessels can be added as needed to accommodate virtually any amount of liquid storage capacity required.  And storage can be quickly scaled up, scaled down, and re-deployed as your operation changes.  Learn about our skid mounted options here.

FREE ASME Pressure Vessel Material Analysis - MAWP - Max Allowable Working Pressure Guidance

FREE Preliminary Vessel Material Analysis

Without the right data to optimize your vessel design, it's easy to miscalculate design pressure by overcompensating for MAWP.  This can lead to incorrectly sized vessels and other  issues including unnecessary costs, underperforming assets—and disappointing ROI,

Let our AMSE vessel design experts assist you with a FREE preliminary material analysis!  We'll help you determine the right material grade & thickness for your pressure rating for optimal vessel performance, often leading to:

  • Reduced overall vessel weight—and cost
  • More economical constructability
  • More!
