LNG & Cryogenics

Gaseous hydrocarbons can be efficiently transported and stored once they are converted to liquid form without pipelines.

Petroleum gas is liquefied (LPG) at ambient temperature by compression of a few bars, but methane (natural gas) needs to be cooled at -160°C to become LNG.

Cryogenic valves are valves installed in arctic climates, or valves that may be exposed during rapid gas decompression (blowdown), in which case the valve can ‘operate or not operate’ in freezing conditions, depending on the configuration ordered.

Cryogenic valves are often used to handle liquefied gases, which like LNG need to operate at very low temperatures.

JUDU manufactures cryogenicGate, Globe, Check, Ball andButterflyValves andControlValves, which are designed and certified to BS-6364 and extensively tested at -196°C (Helium tested in a liquid nitrogen bath).
