As the world turns to cleaner energy, liquefied natural gas (LNG) plays a key role. But storing it safely is an extraordinary engineering feat—because LNG must stay at -162°C to remain liquid. At such extreme cold, ordinary steel turns brittle and risky.That’s where specialized pressure vessel steel comes in.
Unlike everyday construction steel, this advanced material is engineered to stay tough and strong even in deep freeze. It forms the heart of every LNG storage tank—the inner wall that directly contains the supercold liquid under pressure. Variants like 9% nickel steel are chosen because they keep their reliability where most metals would fail.
Its use doesn’t stop at storage tanks. From the hulls of LNG ships to critical valves and pipelines, this same robust steel ensures safety across the supply chain.
With demand for LNG rising, so does the need for these high-performance steels. Researchers are already developing stronger, more economical versions for tomorrow’s energy needs.
So when you see those sleek LNG terminals, remember the hidden shield inside—the pressure vessel steel that keeps energy safe, secure, and moving forward.
