Product Summary
The CG1.9 is a high-integrity tank container, purpose-built for carrying dangerous goods classified under UN 3394—specifically, alkyl metals that react violently with air and water. Adhering to IMDG CODE and GB/T150 requirements, this tank utilizes a 16MnDR inner shell with a robust thickness of 12mm on both shell and heads. It is capable of withstanding up to 18.2 bar of test pressure while operating safely at a design pressure of 6 bar. This container is ideal for industrial users seeking safe transport of highly sensitive chemical cargo.

Safety Guidelines
-
Tank lacks insulation – not suitable for heat-controlled environments
-
Must be handled only by certified and trained personnel
-
Keep away from water sources to prevent fire or explosion due to alkyl metal reactivity
-
Do not operate beyond 6 bar; inspect the relief valve frequently
-
Ground the unit before and during material transfer to dissipate static charge
-
Continuous temperature monitoring is essential to remain within the -40°C to +70°C range
Usage Scenarios
-
Chemical Transport Logistics: Used for transferring reactive substances including alkyl metals safely
-
Specialty Manufacturing: Suitable for facilities producing highly reactive compounds
-
Defense Operations: Transport solution for high-risk chemicals in military supply chains
-
Hazard Control Missions: On-site containment for hazardous material during emergency leaks or spills
-
Chemical Plant Integration: Movement of unstable intermediates between processing sites
