LNG Valve

Use of LNG Valve

Ball valves, gate valves, check valves, globe valves, and butterfly valves, made of titanium, nickel aluminum bronze, and duplex stainless steel, are recommended for pipeline transportation of liquefied natural gas. Our valves bear corrosion resistance, long service life, and long replacement cycle, which saves project costs and later maintenance costs for you.

Weidouli Valves For LNG

The gas is first extracted and transported to a processing plant where it is purified by removing any condensates such as water, oil, mud, as well as other gases such as CO2 and H2S. An LNG process train will also typically be designed to remove trace amounts of mercury from the gas stream to prevent mercury from amalgamizing with aluminum in the cryogenic heat exchangers. The gas is then cooled down in stages until it is liquefied. LNG is finally stored in storage tanks and can be loaded and shipped.

For this special application, the valve material that has to consider the marine environment and sea water fluid. So to serve this application, we should select special materials (duplex steels, nickel alloys) and also consider extreme service conditions (low temperature, anti-wearing internals) to choose the best internal materials.
