Cryogenic LNG Tank Semi-trailer

The Cryogenic LNG Tank semi-trailer are mainly used for the storage and transportation of LPG, LNG, Propylene, ethylene oxide, propylene oxide, butadiene such as a special tank truck. Our company has imported some advance technical designing, facilities, and technology. Also using modernization management for product quality detection, follow the nation pressure vessel standardization to fabricate and inspection strictly.
