Our Process

Step-by-Step. No Surprises.

System Mapping & Vacuum MonitoringStep 1

Before any mechanical dismantling, the vacuum level must be monitored using existing vacuum transducers or pump-out/relief port nozzles. Complete system mapping of all cryogenic storage vessels, piping, and associated controls.

Dry Inert Gas Backfill (Vacuum Breaking)Step 2

The vacuum must be broken using a strictly controlled purge of dry, oil-free inert gas — typically high-purity nitrogen. Ambient air must never be used — introducing atmospheric air causes immediate condensation and freezing of moisture, creating ice buildup that damages internal piping, compromises valves, and creates unsafe conditions. The VJP inner carrier pipe is surrounded by an outer jacket with the annular space evacuated to extreme vacuum levels (often 9 microns or less) with multi-layered super insulation.

Controlled Venting of Cryogenic GasesStep 3

1 liter of liquid nitrogen expands to nearly 700 liters of gas at room temperature. Venting follows strict spacing and atmospheric dispersion models per EIGA Doc 154. For CO₂: uncontrolled depressurization causes auto-refrigeration, flashing liquid into solid dry ice at -78°C. Vaporizers must be used to heat the liquid, maintaining pressure above the triple point. Vent stacks must not be interconnected — incompatible gas could freeze inside a vent line, blocking emergency pressure relief paths.

Sequential Disconnection & Piping DismantlingStep 4

Once vacuum is neutralized and system is at atmospheric pressure, VJP sections are mechanically separated at weld sockets or outer couplings. Cold-cutting techniques prevent heat-affected zone damage to stainless steel metallurgy.

Heavy Lift Extraction & TransportStep 5

Heavy lift planning accounts for perlite insulation shifting center of gravity. ASME U-1 Manufacturer's Data Report preservation and National Board nameplate protection. Certified transport on specialized flatbed and lowboy trailers.

Why Choose Us

The CryoTank Difference

01 / 03

Cryogenic-First Identity

No competitor leads with cryogenic decommissioning as their primary identity. TransTech/MIG/CTR bury it in service lists; Matrix Service wraps it in "lifecycle support" language.

Step-by-Step Process Transparency

No competitor shows a step-by-step decommissioning process. This reduces the high anxiety facility managers experience with these projects.

Asset Recovery Offsets Your Cost

Strategic recovery of ASME U-1 documented vessels, preservation of National Board nameplates, and secondary market placement of OEM equipment from Chart Industries, Taylor-Wharton, and INOX India.

Small and Mid-Size Operators Welcome

Hospitals, food processing, pharmaceutical, university labs — segments completely uncontested by TransTech/Matrix-scale competitors.

Zero-Incident Safety Culture

HAZOP studies, daily JSAs, universal Stop Work Authority. CHMM/CSP-certified leadership on every project.
