Which imported valves are required for LNG projects
Thread Content
Hello everyone, does anyone know what kind of imported valves are used in LNG projects?
It’s mainly for low temperatures, and there are also elements for anti-surge, such as J/T valves and track valves. Of course, some can also use domestic ones, such as anti-surge valves.
Low-temperature butterfly valves, globe valves, as well as safety valves and control valves
Ball valves are also quite large, as are check valves and the like.
The tank area is primarily equipped with low-temperature valves, with ball valves and plug valves being the most common; there are also some butterfly valves, gate valves, safety valves, and control valves. Similar to gas pipelines, a large number of pneumatic-operated ball valves, plug valves, and gate valves are used there, all of which require grease sealing.
As far as I know, most LNG facilities use domestically produced valves. However, for control valves in critical areas, such as isolation valves and pressure/flow control valves, domestic manufacturers are not able to produce them to a satisfactory standard, so imported valves are generally used instead
Our company sells a large quantity of emergency shut-off valves for tanks, made in Germany
Apart from safety valves such as safety valves and vent valves on the storage tanks, almost all the valves are of domestic manufacture. Of course, if one has the money, they can also choose imported valves; there are those who opt for imported valves. There are also many cases of internal leakage in the valves; this may be caused by inadequate purging of the valves, with the exact reason unknown
