Handling liquefied natural gas (LNG) requires Pressure Vessels that combine structural integrity, thermal performance, and regulatory compliance. TRG Supply provides LNG storage tanks built for industrial applications where safe, long-term containment of LNG is critical.
These LNG tanks are designed to operate under demanding temperature and pressure conditions, maintaining fuel quality and system reliability. Each LNG storage tank is supplied with documentation and certifications required for regulatory approval and ongoing operational inspections.
TRG Supply designs and fabricates custom LNG storage tanks built to hold liquefied natural gas at roughly -162°C without losing structural integrity or letting product boil away faster than your facility can use it. We work as a custom LNG tank manufacturer, not a parts catalog, so every vessel is engineered around your capacity, site footprint, and process conditions.
Our cryogenic vessel experience covers double-wall containment, vacuum-jacketed and insulated designs, and boil-off management for industrial fuel, peak-shaving, marine bunkering, and distribution operations. Each liquefied natural gas tank is supplied with ASME-compliant construction and documentation that supports your inspection and approval process.

An LNG tank is a cryogenic storage vessel that holds natural gas in liquid form after it has been cooled to about -162°C (-260°F). Liquefying the gas shrinks its volume roughly 600 times, so a single tank stores far more usable fuel than a comparable gaseous-pressure vessel.
LNG storage tanks sit at the center of distribution and process operations: receiving terminals, peak-shaving plants, satellite stations, power generation sites, and marine fueling points all rely on them to hold product between deliveries and feed downstream regasification or transfer systems.
The key difference between an LNG tank and a standard pressure vessel is temperature. A standard vessel manages pressure at ambient conditions; a cryogenic LNG vessel must also handle extreme cold, thermal contraction of the steel, and continuous heat-leak management. That changes the materials, the insulation, and the code requirements, which is why these tanks are engineered as a distinct category of cryogenic pressure vessel.
The right tank type depends on your stored volume, site space, and how the LNG moves through your operation. Here is how buyers typically evaluate the main configurations.
Above-ground LNG tanks are the most common choice for industrial and commercial sites because they are quicker to install, easier to inspect, and simpler to relocate than buried systems. They suit fuel storage, satellite stations, and process facilities where surface space is available and routine access matters.
Horizontal bullet tanks are a practical solution for small to mid-range capacities, typically used at fueling stations, fleet depots, and industrial fuel systems. Their double-wall, vacuum-insulated design keeps a compact footprint while limiting boil-off, which makes them popular for distributed LNG fuel storage.
Spherical tanks distribute stress evenly across their surface, which suits larger volumes and higher-pressure LNG containment. They are common in marine and larger terminal settings where capacity and structural efficiency outweigh footprint concerns.
Double-wall cryogenic LNG tanks use an inner vessel rated for cryogenic service inside an outer shell, with insulation or a vacuum jacket between them. This construction minimizes heat ingress, controls boil-off, and adds a layer of containment, making it the standard approach for long-term LNG storage where product loss and safety are priorities.
Storing LNG well is a cryogenic engineering problem, not just a pressure problem. A few factors drive nearly every design decision in a cryogenic LNG vessel.
Material selection is where cryogenic service gets serious. Ordinary carbon steel becomes brittle at LNG temperatures, so an LNG tank uses metals proven to keep their toughness in the cold.
These choices tie directly to ASME material requirements and low-temperature impact resistance. Under ASME Section VIII, cryogenic vessel materials generally require impact testing per ASME UHA-51 to confirm they will not fracture in the cold.
That is why we treat UHA-51 impact testing for cryogenic vessels as a core part of LNG tank construction rather than an afterthought, the same discipline we apply to other low-temperature pressure vessels.
LNG storage is heavily regulated, and a tank that cannot demonstrate compliance is a project risk. TRG Supply builds and documents tanks to support the standards your project must satisfy, while your authority having jurisdiction confirms final acceptance.
We don’t provide legal or regulatory advice, but we do supply tanks engineered and documented so your compliance and inspection process moves smoothly.
An LNG storage tank is a cryogenic vessel that holds natural gas in liquid form at about -162°C. Cooling the gas to a liquid cuts its volume around 600 times, so the tank stores a large amount of usable fuel in a compact space.
LNG is stored at approximately -162°C (-260°F), the point at which natural gas remains liquid at near-atmospheric pressure. Maintaining that temperature is why insulation and boil-off control are central to tank design.
LNG tanks use cryogenic-rated materials such as stainless steel, 9% nickel steel, and aluminum alloys. These metals stay tough at extreme cold, where standard carbon steel would become brittle.
LNG storage tanks are commonly built to ASME Section VIII, with reference to NFPA 59A for LNG facilities, National Board requirements, and applicable DOT and state or local rules. TRG Supply builds and documents tanks to support these requirements.
A cryogenic LNG vessel is a pressure vessel engineered to safely contain liquefied natural gas at extremely low temperatures. It combines cryogenic materials, insulation or a vacuum jacket, and boil-off management in one system.
A standard pressure vessel manages pressure at ambient temperature, while an LNG tank must also handle cryogenic cold, thermal contraction, and continuous heat leak. That requires different materials, insulation, and code provisions such as UHA-51 impact testing.
A small amount of LNG always vaporizes despite insulation. Systems manage this boil-off gas through pressure control, venting, or recovery, keeping tank pressure safe and reducing product loss.
Yes. TRG Supply designs LNG tanks around your capacity, consumption rate, site footprint, and process conditions, including double-wall and vacuum-jacketed configurations.
