DSW provides industrial gas transportation equipment for applications involving liquefied natural gas (LNG), liquid nitrogen (LIN), liquid oxygen (LOX), liquid argon (LAr), and other industrial gases. Equipment selection is based on gas compatibility, operating conditions, transport requirements, and applicable safety standards.
What Are Gas Transport Solutions? (Storage → Transport → Distribution)
Industrial gas transport solutions connect gas production, bulk storage, transportation, and end-use facilities. They are designed to maintain the required pressure, temperature, and containment conditions throughout the delivery process.
A complete industrial gas supply chain generally includes three interconnected stages:
- Gas storage: Cryogenic storage tanks, pressure vessels, and cylinder systems hold gas before transportation or distribution.
- Gas transportation: ISO tank containers, cryogenic tanker trailers, LNG transport trailers, and tube trailers move gas between facilities.
- Gas distribution: Storage tanks, vaporizers, pressure-control equipment, and distribution pipelines deliver gas to the point of use.
Transportation equipment must be selected according to the physical state of the gas, required delivery capacity, route conditions, and local transportation regulations.
