ISO ASME Tank CONTAINER
DSW’s 20m³ ISO ASME Cryogenic Tank is designed according to the ASME Boiler and Pressure Vessel Code (BPVC), ensuring the highest standards for safe storage and transportation of cryogenic liquids such as liquid oxygen (LOX), liquid nitrogen (LIN), liquid argon (LAR), and liquid carbon dioxide (CO₂). These tanks are ideal for industrial, medical, and research applications, offering reliable performance, durability, and compliance with international shipping standards.
Key Features
- Standardised Shipping: Compatible with 20-foot container handling, cargo vessels, and trains.
- Pressure Vessel Compliance: ASME-certified construction for safe pressurized storage and transport.
- Multi-Layer Insulation: Vacuum-perlite insulation minimizes boil-off and maintains stable internal pressure.
- Versatile Applications: Suitable for LNG, industrial gases, chemicals, and medical-grade cryogens.
ASME Compliance & Safety
Our ISO ASME tanks adhere to strict ASME code standards for design, materials, construction, inspection, and documentation. Each tank is built and tested to ensure reliable, safe, and long-term operation.
