Vacuum Insulated LCO₂ Storage Tank
Product Summary
Vacuum Insulated LCO₂ Storage Tank is engineered for static storage of liquefied carbon dioxide (LCO₂) at working pressures up to 2.2 MPa (or customized). Built strictly to international pressure vessel codes, these tanks ensure precise pressure maintenance and ultra-low product boil-off rates.

FAQ
Q: What design codes and international certifications do your LCO₂ tanks comply with?
A: Our tanks are manufactured in accordance with ASME Section VIII Division 1, European CE-PED (EN 13458), or GB standards. Full third-party inspection reports (TÜV, BV, SGS) and manufacturer data reports are available upon request.
Q: How do you guarantee long-term vacuum stability?
A: We combine multi-layer insulation material with advanced vacuum baking, molecular sieve getters, and precise helium leak detection to achieve high vacuum retention over years of operation without continuous pumping.
Q: Can the tank parameters be customized to integrate into an existing pipeline network?
A: Yes. Nozzle orientations, flange standards (ANSI, DIN, JIS), instrumentation protocols (4-20mA, Modbus), and pressure-building circuit capacities can be engineered to fit your current infrastructure.
Q: What is the lead time for standard vs. customized tanks?
A: Standard models (10m³ to 50m³, 1.6MPa/2.2MPa) typically have a production cycle of 45–60 days. Fully customized or ASME/CE-certified large-capacity tanks require 60–90 days including third-party inspection time.
Q: How do you handle installation and commissioning for overseas buyers?
A: We provide complete foundation drawings, P&ID layouts, and installation manuals. For large or complex turnkey projects, we dispatch field service engineers for on-site supervision and commissioning or provide remote assistance via video conference.
Q: What maintenance is required during operation?
A: LCO₂ vacuum tanks require low daily maintenance. Periodic checks include inspecting safety relief valve calibration, monitoring vacuum port integrity, checking pressure building valves, and verifying differential level gauge accuracy every 12 to 24 months.
Q: How are the tanks secured against corrosion during sea freight?
A: Outer shells are shot-blasted to Sa 2.5 standard and coated with a heavy-duty epoxy primer and polyurethane topcoat designed for marine and harsh industrial environments. Critical valves and connections are sealed with water-impermeable protective covers.
