Application Practice of Low-temperature Trunnion Ball Valves in the LNG Field (1) LNG Receiving Terminal The LNG receiving terminal is an important link in the liquefied natural gas industry chain, responsible for receiving, storing, and transshipping LNG. In the receiving terminal,
low-temperature trunnion ball valves are widely used in key parts such as unloading arms, storage tank inlets and outlets, and vaporizer inlets and outlets. For example, the
low-temperature trunnion ball valve installed on the unloading arm can accurately control the flow of LNG from the transport ship to the receiving terminal, ensuring the safety and efficiency of the unloading process. At the inlets and outlets of the storage tank, the
low-temperature trunnion ball valve is used to control the inflow and outflow of LNG. Its reliable sealing performance can effectively prevent the leakage of LNG and ensure the safe operation of the storage tank.
(2) LNG Carrier The LNG carrier is an important tool for the transportation of liquefied natural gas, and its safety is directly related to the stability of the entire transportation process. On the carrier,
low-temperature trunnion ball valves are installed at the inlets and outlets of the cargo holds and in the pipeline system to control the loading and unloading of LNG. Since the carrier is affected by various complex environments during its voyage at sea, higher requirements are put forward for the reliability and durability of the valves. The high-strength structure and excellent sealing performance of the
low-temperature trunnion ball valve enable it to adapt to the special working conditions of the carrier and ensure the safety of LNG during transportation.
(3) LNG Vaporization Station The LNG vaporization station is a place where liquid LNG is vaporized into gaseous natural gas, and the performance of its equipment directly affects the vaporization efficiency and gas supply quality. In the vaporization station,
low-temperature trunnion ball valves are used to control the flow and pressure of LNG to ensure the stable progress of the vaporization process. By precisely adjusting the opening degree of the valve, precise control of the LNG flow can be achieved, thereby improving the vaporization efficiency and reducing energy consumption. In addition, the fast opening and closing ability of the
low-temperature trunnion ball valve also enables it to quickly cut off the LNG supply in case of an emergency, ensuring the safety of the system.
