We also provide semi and finished machined components and can provide cladding, pressure testing, assembly and fabrication services.


LNG is non-corrosive and non-toxic when maintained in liquid form but the materials used to contain it during transportation need to be carefully sourced. If it vaporises, LNG can become explosive or emit thermal radiation. So, storage containers need to be made from steel that can maintain its integrity at extremely low temperatures.

Nickel steel alloy is the most effective choice because it remains deductive – and won’t crack or shatter – even at -196*C.

Stainless steel is also valuable in the LNG sector. It is highly weldable without undergoing phased transitions and has a high resistance to corrosion. High quality stainless can withstand the impact of low temperatures due to its high ferrite levels.
