Product Overview This high-specification 20-foot ISO tank container is engineered specifically for the safe storage and international transport of Liquefied Petroleum Gas (LPG). Combining advanced engineering with a compact, standardized design, this vessel meets rigorous international maritime and overland regulations. It holds dual compliance with ASME boiler and pressure vessel codes alongside UN T50 portable tank certifications, ensuring seamless cross-border logistics and maximum operational safety.

Structural Design and Materials Built within standard 20ft ISO dimensions (6,058 mm length × 2,438 mm width × 2,591 mm height), the tank optimizes containerized transport infrastructures. The pressure vessel shell is constructed from high-grade Q345R steel, a specialized material renowned for its high tensile strength and excellent performance in pressure-retaining applications. Featuring a robust plate thickness of 13.5 mm, the tank delivers a total volume capacity of 22.5 m³.

To preserve structural integrity during transit under intense ambient conditions, the tank container is equipped with a high-durability aluminum alloy sunshield. This shield effectively reflects solar radiation, mitigating pressure build-up from external heat exposure. The overall design features a tare weight of 13,000 kg and supports a maximum allowable gross mass (MGW) of 36,000 kg.

Operating Parameters and Codes The container is engineered to withstand demanding operating environments. It features a design pressure of 1.77 MPa and is rated for an extensive design temperature range spanning from -40°C to +55°C. This wide thermal threshold guarantees safe operation across diverse climatic zones. The tank’s design, fabrication, and testing comply strictly with leading global frameworks, including JB/T4781, IMDG, ISO 1496-3, and GB/T16563 standards.

Valve and Fitting Configurations The intermodal tank features versatile options for valve and accessory integration to suit varied operational preferences:

Configuration A: Equipped with a premium FORT VALE safety valve, high-quality domestic ball valves, and a high-quality domestic mechanical emergency shut-off valve. This configuration is designed without a liquid level gauge.
Configuration B: Configured for enhanced performance, featuring a premium FORT VALE safety valve combined with imported high-performance FORT VALE ball valves and components.
