LNG Low-Temperature Loading Arm  

LNG Low-Temperature Loading Arm (Liquefied Natural Gas Loading Arm) is a tank truck / ship loading/unloading equipment specially designed for an ultra-low temperature environment of -162°C, with core advantages of low-temperature resistance, high sealing performance and high safety.

Applicable media: LNG (liquefied natural gas), liquid nitrogen, liquid ethylene, etc.

Design temperature: -196°C ~ +70°C (ultra-low temperature resistant)

Operating temperature: -162°C (boiling point of LNG)

Design pressure: 1.6MPa / 2.5MPa

Nominal diameter: DN50 / DN80 / DN100 (DN50 commonly used for liquid/vapor phases)

Materials:

Fluid pipe: 304L / 316L stainless steel (cryogenically treated)

Seals: reinforced PTFE (polytetrafluoroethylene), low-temperature FKM

Structure: column, liquid phase arm, gas phase (BOG) recovery arm, swivel joint, emergency release valve, balance cylinder, vacuum insulation layer

Insulation: multi-layer vacuum insulation with extremely low cold loss

Ultra-low temperature resistance: no brittle fracture or seal failure at -196°C

Dual-pipe design: liquid phase (LNG) + gas phase (BOG recovery) to reduce evaporation

Standard safety configuration: emergency release valve (automatic sealing to prevent leakage in case of accidental pull-off)

Flexible rotation: multi-degree-of-freedom swivel joints for adaptation to tank truck manholes

Static conductive & oil-free: explosion-proof, free from oil contamination
