LNG Fuel System Servicing involves specialized maintenance for liquefied natural gas fuel systems. It includes inspection, cleaning, and repair of components to ensure optimal performance. Specialized services cater to unique requirements of LNG-powered vehicles and equipment.

Size: Varies based on vessel or storage tank capacity, typically ranging from 1,000 to 200,000 cubic meters.

Grade: High-purity LNG with methane content exceeding 85%, minimal impurities (sulfur, CO2, water).

Viscosity: Low viscosity, approximately 0.11–0.15 cP at -162°C.

Buoyancy: LNG is lighter than water (density ~430–470 kg/m³ at boiling point).

Material: Cryogenic-grade stainless steel (304L, 316L), nickel alloys, and insulated composites for tanks/piping.

Pressure Rating: Storage tanks typically 4–10 bar, piping systems designed for cryogenic conditions.

Thermal Conductivity: Low (~0.15–0.2 W/m·K) to minimize heat transfer.

Insulation: Multi-layer vacuum or perlite-based for tanks; foam/PVC for pipelines.

Safety Standards: Compliant with IGC, ISO 20519, and EN 1473.

Servicing Tools: Cryogenic-rated valves, pumps, and leak-detection systems.
