T75 40000L LNG ISO Container

BRIEF

The T75 40,000L LNG ISO Container produced by CSCTRUCK China Tank Truck is a high-performance cryogenic intermodal tank designed for the safe and efficient transportation of liquefied natural gas (LNG) across road, sea, and rail networks. Manufactured in compliance with TSG R0005-2011 Mobile Pressure Vessel Safety Technical Inspection Regulations, the IMDG Code, JB/T 4780-2002 LNG Tank Container standards, and the Container Inspection Code-2012, this unit meets stringent international safety and engineering requirements for hazardous gas transport (Class 2.1).

Structurally, the LNG ISO container follows a T75, 1AA ISO framework with overall dimensions of 12,192 × 2,438 × 2,591 mm. It has a total volume of 40,440 L and an effective working volume of 36,400 L, with a rated filling ratio of 90%. The tare weight is 18,023 kg, the maximum payload capacity is 14,700 kg, and the rated gross weight is 32,723 kg. It also supports a stacking load of up to 192,000 kg, ensuring compatibility with multi-modal logistics operations.

The inner vessel is constructed from S30408 stainless steel, while the outer jacket uses Q345R pressure vessel steel. It is designed for extreme cryogenic conditions, with an internal working temperature down to -162°C and a design temperature of -196°C. The maximum working pressure is 0.7 MPa, with a design pressure of 0.8 MPa, and the system operates under high-vacuum multilayer insulation to minimize boil-off, achieving a static evaporation rate of ≤0.18% per day.

Safety systems include pneumatic emergency cut-off valves (DN50/DN32), ZA25-5B low-temperature safety valves, CYJ-1 level gauges, and DN50 loading/unloading flange connections. The container also features fusible plugs (70±5°C), pressure gauges (0–1.6 MPa), and explosion protection ports (DN80), ensuring comprehensive operational safety.

With a design service life of 15 years and corrosion allowances of 0–1 mm, this LNG ISO container delivers robust durability, high thermal efficiency, and reliable performance for global LNG logistics.
