LNG ISO Tanks
LNG Tank Containers are special intermodal tanks designed to transport and store liquefied natural gas (LNG) at cryogenic temperatures.
They are built according to the ISO standards (International Organisation for Standardization) and are used to transport LNG in bulk efficiently.
Product Features
1. Unique internal structural design, excellent thermal insulation, loss-free long-distance transportation;
2. GB150, ASME, AS1210, EN13530 and other relevant national and international standards; Larger volume, lighter weight and safely easy operation. ;
3. Conform to IMDG/ADR/RID and other international requirements concerning the transportation of dangerous items suitable for multi-modal global transport;
4. The requirements of LR (Lloyd’s Register), DNV (Det Norske Veritas), CCS (China Classification Society), or relevant inspection and certification services.

Liquefied Natural Gas| LNG Tank Container
DSW is an industry-leading designer, engineer and manufacturer of LNG transportation and storage such as LNG containers and LNG vaporizer Skid.
Transporting LNG in ISO tanks is an innovative and effective alternative to conventional natural gas distribution.
LNG is odorless, colorless, non-toxic, and non-corrosive.
LNG, or Liquefied Natural Gas, is natural gas that has been cooled down to liquid form for ease and safety of non-pressurized storage or transport.
Our testing ensures all of our Natural Gas storage tanks for natural gas meet ISO standards and DOT regulations.
DSW works directly with each customer to provide custom solutions based on pressure and holding requirements.
DSW offers the highest-quality cryogenic mobile tanks at competitive prices. Our cryogenic storage vessels are used worldwide to safely transport and store cryogenic or liquid gas.
Specifications
LNG Tank Container – 40ft/20ft/custom size
Liquefied Natural Gas Tank Containers are designed worldwide to increase the energy supply chain by allowing safe storage and transport of liquefied gas.
LNG is becoming a viable alternative to fossil fuels. Natural gas delivered in LNG tank containers is a great energy alternative for remote and urban areas.
