ASME Certified LNG Tank – Double-Wall Cryogenic Storage Solution

Asme-certified LNG storage tanks – Double-wall cryogenic storage solutions

Our double-wall liquefied natural gas (LNG) storage tanks are specially designed for reliable and long-term low-temperature storage of LNG. Certified by ASME, they are an excellent storage solution for energy centers, industrial plants, LNG refueling stations and Marine fuel supply systems. This storage tank is specially designed to withstand extreme low-temperature conditions and features safety, thermal efficiency and stable operation, making it the preferred choice for projects that prioritize compliance and performance.

The core of this LNG storage tank is its double-wall structure design, which is a key feature for eliminating the risks of LNG leakage and environmental pollution. The inner tank is made of high-quality austenitic stainless steel and was selected for its excellent low-temperature toughness and corrosion resistance, ensuring compatibility with ultra-cold LNG. The outer tank is made of strong carbon steel and can serve as a protective barrier against external impacts, weathering and mechanical damage. Between the two walls, we combine high-performance vacuum insulation materials with perlite filling to effectively reduce the generation of evaporative gas (BOG) by minimizing heat entry. This advanced insulation system significantly reduces operating costs and enhances the efficiency of LNG storage.

What sets our products apart is that they comply with the ASME Boiler and Pressure Vessel Code (BPVC) standard, a globally recognized certification that ensures strict quality control throughout the manufacturing process. From raw material procurement to welding, non-destructive testing and the final hydrostatic pressure test, every step strictly follows the ASME guidelines. In addition to ASME certification, our LNG storage tanks can also be customized to meet regional standards such as PED (EU Pressure Equipment Directive), ISO 14692 and GB standards, ensuring seamless deployment in markets such as North America, Europe and Asia.

This double-wall liquefied natural gas storage tank is equipped with an intelligent safety monitoring system that can prevent operational risks in real time. This system includes integrated pressure and temperature sensors, a continuous BOG monitoring module, and a leakage detection alarm that is automatically triggered when any abnormal situation is detected. To enhance safety, we have also equipped the storage tanks with pressure reducing valves, emergency shut-off devices and fire extinguishing systems, all of which are tailor-made to meet the strict safety requirements of low-temperature storage facilities.

This ASME-certified LNG tank is highly versatile and can be customized in capacity to suit various application scenarios.
