液化天然气(LNG) 应用广泛,包括航天发射、金属加工和真空炉、医疗技术、电子、水处理、能源发电以及食品工业等等。如今。 工业气体 以液化天然气(LNG)的形式向客户输送。 低温 温度,使LNG能够在现场储存,供以后使用。
液化天然气(LNG)罐和管道
为了将液化天然气保持在极低的温度下,液化天然气通常储存在双壁罐中,或用真空夹套液化天然气管道运输,该管道由两个圆柱形容器、一个内罐(压力容器)和一个外夹套组成。内、外容器之间的空间中的空气称为环形空间,通过真空泵将其抽空至特定的真空度,形成真空,为LNG提供真空绝热。
LNG真空计
The vacuum insulation is a critical element in a LNG tank, making vacuum gauges, vacuum measurement, and vacuum control a top priority. Televac® offers a wide range of analog vacuum gauges and digital vacuum gauges for liquefied natural gas (LNG) applications including our 2A thermocouple micron vacuum gauge, our 2A VacuMini thermocouple micron vacuum gauge, the robust 2V6 thermocouple micron vacuum gauge, the small and portable Vacuguard™ vacuum controller, and the easy to use MX2A active vacuum gauge. For larger installations of liquefied natural gas (LNG) piping, a controller like the MX200 vacuum controller is often used.
