Low-temperature loading arm (also commonly known as LNG loading arm) is special pipeline equipment designed for the loading and unloading of ultra-low temperature media at -20℃ ~ -196℃, mainly used for the sealed loading and unloading of liquefied natural gas (LNG), liquid nitrogen, liquid oxygen, low-temperature ethylene and other media for truck and railway tankers.
Main Parameters
Design temperature: -196℃ ~ +70℃
Operating temperature: -162℃ (atmospheric boiling point of LNG)
Design pressure: 1.6 MPa
Nominal diameter: Liquid phase DN50 / DN80, Gas phase DN25 / DN50
Applicable Media
LNG (Liquefied Natural Gas)
Liquid nitrogen, liquid oxygen, liquid argon
Low-temperature chemicals such as liquefied ethylene and liquefied propane
Application Scenarios
LNG filling stations, liquefaction plants and receiving terminals
Cryogenic gas (air separation) and low-temperature chemical media handling
Sealed loading for railway and highway tankers
