Cryogenic Tank Manufacturing for Industrial Gas Storage
DSW Industry manufactures and supplies vacuum-insulated cryogenic tanks and vessels designed for the storage and handling of liquefied gases at cryogenic temperatures. Our tanks are engineered according to the stored medium, required capacity, working pressure, operating conditions, installation environment and applicable design or certification requirements.
Typical cryogenic media include liquid nitrogen (LIN/LN₂), liquid oxygen (LOX), liquid argon (LAr), liquid carbon dioxide (LCO₂) and LNG. Depending on the application, tanks can be supplied in vertical or horizontal configurations with customized piping, valves, instrumentation, pressure-building systems and filling or discharge connections.
Our manufacturing scope covers engineering and fabrication, material preparation, vessel welding, vacuum insulation, inspection, pressure and leak testing, final assembly and technical documentation.
For bulk industrial gas applications, cryogenic storage tanks can also be integrated with vaporizers, cryogenic pumps and downstream gas supply systems to provide a complete gas storage and distribution solution.

Cryogenic Tanks We Manufacture
Vertical Cryogenic Storage Tanks
Vertical vacuum-insulated storage tanks are designed for stationary bulk storage where available installation space favors a vertical configuration. They are commonly used for liquid nitrogen, oxygen, argon and carbon dioxide storage.
Horizontal Cryogenic Storage Tanks
Horizontal cryogenic tanks provide an alternative configuration for installations with specific height, foundation or access requirements. Tank dimensions, connections and support structures can be adapted to the project.
LNG Storage Tanks
DSW Industry manufactures vacuum-insulated LNG storage equipment for applications requiring controlled storage and transfer of liquefied natural gas. LNG tank design depends on capacity, pressure, installation conditions, applicable codes and project requirements.
Microbulk Cryogenic Tanks
Microbulk tanks provide on-site storage for users with continuous or regular demand for cryogenic gases. They can be configured with appropriate filling, liquid withdrawal, gas outlet, pressure-building and instrumentation systems.
Transport and ISO Cryogenic Tanks
Transport and ISO cryogenic tanks are designed for the storage and transportation of liquefied gases. Their design must account for transport conditions, pressure requirements, applicable transport regulations and the destination market.

Materials and Vacuum Insulation
Cryogenic tanks require materials and insulation systems suitable for extremely low operating temperatures. The inner vessel is commonly manufactured from stainless steel or another material specified for cryogenic service, while the outer vessel provides structural protection and contains the insulation system.
The space between the inner and outer vessels is evacuated to reduce heat transfer. Depending on the tank design, perlite insulation or multilayer insulation (MLI) may be used within the vacuum space.
Effective vacuum insulation reduces heat ingress and helps limit liquid evaporation during storage. The insulation system, vacuum performance and vessel construction must be considered together when designing a cryogenic storage tank.
Cryogenic Tank Components
A cryogenic storage tank is more than the pressure vessel itself. Its piping and instrumentation must be configured for safe filling, storage, pressure control and liquid or gas withdrawal.
- Filling and liquid withdrawal connections
- Gas outlet and vapor return connections
- Pressure-building system
- Economizer or pressure-control system
- Safety relief valves
- Isolation valves and cryogenic piping
- Pressure gauges and transmitters
- Liquid-level measurement system
- Vacuum gauge or vacuum service connection
- Vaporizer connection
- Drain and vent connections
- Project-specific instrumentation and control components
Component selection depends on the stored medium, operating pressure, required flow rate, installation arrangement and applicable safety requirements.
Cryogenic Tank Manufacturing Process
1. Engineering & Design
The manufacturing process begins with the required gas, capacity, working pressure, design temperature, installation conditions, connections, insulation system and applicable design standards.
2. Material Preparation
Specified materials are prepared and verified according to the approved design and manufacturing requirements. Material identification and traceability are maintained where required.
3. Vessel Fabrication
The inner and outer vessels are fabricated according to approved drawings and manufacturing procedures. Dimensional control is maintained throughout fabrication.
4. Welding & Inspection
Pressure-retaining components are welded using controlled procedures. Welds and fabricated components are inspected using applicable visual, dimensional and non-destructive examination methods.
5. Vacuum & Pressure Testing
Completed vessels undergo applicable pressure, leak and vacuum testing. Testing verifies the integrity of the pressure boundary and insulation system before final completion.
6. Final Inspection & Delivery
Final inspection covers vessel condition, dimensions, valves, instrumentation, safety devices, identification and documentation. Equipment is then prepared for shipment according to the project and transport requirements.
Quality Control and Cryogenic Tank Testing
Quality control is integrated throughout the cryogenic tank manufacturing process rather than performed only at final inspection.
- Material verification and traceability
- Welding procedure and fabrication control
- Visual and dimensional inspection
- Non-destructive testing where specified
- Pressure testing
- Leak testing
- Vacuum testing and monitoring
- Safety-device and valve inspection
- Final assembly and functional inspection
- Inspection records and project documentation
The exact inspection and testing program depends on the tank design, applicable code, customer specification and certification requirements.
International Standards and Compliance
Cryogenic tank design and manufacturing requirements vary according to the equipment type, stored medium, pressure, installation conditions, transport application and destination market. DSW Industry can work according to applicable requirements such as:
- ASME Boiler and Pressure Vessel Code, where applicable
- EN standards for applicable pressure equipment
- PED requirements for applicable equipment placed on the European market
- GB / Chinese pressure-vessel standards
- ADR requirements for applicable transport equipment
- ISO quality-management requirements where relevant to the project
- Customer-specific inspection, testing and documentation requirements
Applicable standards should be confirmed during engineering because a particular code or conformity requirement may depend on the tank type, pressure, medium, installation and destination.
How to Select a Cryogenic Storage Tank
Choosing a cryogenic storage tank requires more than selecting a nominal tank capacity. The complete operating and installation requirements should be evaluated before manufacturing.
- Stored medium: Determine whether the application uses LIN/LN₂, LOX, LAr, LCO₂, LNG or another cryogenic liquid.
- Required capacity: Consider normal consumption, peak demand, delivery frequency and required reserve.
- Working and design pressure: Select pressure ratings based on the operating system and applicable code.
- Operating temperature: Confirm the minimum design temperature for the stored medium.
- Tank orientation: Choose vertical or horizontal construction according to available space and installation requirements.
- Filling and withdrawal: Define filling connections, liquid outlets, gas outlets and required flow rates.
- Pressure control: Determine whether a pressure-building system, economizer or other pressure-control arrangement is required.
- Vaporization: Consider whether the storage tank will be connected to an ambient or other cryogenic vaporizer.
- Safety and instrumentation: Specify relief valves, pressure measurement, level measurement and other required controls.
- Applicable standards: Identify the design, inspection, certification and transport requirements for the destination market.
- Installation conditions: Confirm foundation, access, maintenance clearance, piping layout and site restrictions.
