Turnkey small cryogenic tank installation for LN2, LOX, LAr and CO2. Covers site layout, piping, purging, leak test and inspection filing.

Quick Easy Cool cryogenic tanks are a popular alternative to Dewar cylinders. Compact and fast to deploy, they are widely adopted for laser cutting, food freezing, lithium battery manufacturing, pharmaceutical and welding applications. As special pressure vessels, they require standardized installation to avoid risks such as leakage, overpressure and cryogenic burns.

1. Site Survey & Solution Planning

Confirm the cryogenic medium first, as safety spacing and supporting requirements differ for liquid nitrogen, liquid oxygen and carbon dioxide.

Place the tank outdoors in a well-ventilated area, away from heat sources, open flames and high-traffic zones. A reinforced concrete foundation with leveling and drainage is required to prevent uneven settlement that may crack pipelines. Match tank capacity, vaporizers and pressure regulators according to your peak gas demand. Prepare equipment certificates and complete advance filing for special pressure vessel construction.

2. Lifting, Positioning & Piping Work

Check pressure vessel certificates and inspect the outer shell and vacuum layer for damage before installation. Use soft slings for lifting, level the tank and fasten anchor bolts securely.

Stainless steel pipes and argon arc welding are used for cryogenic piping. The system includes ambient air vaporizers, pressure regulating assemblies, safety relief valves and emergency shut-off valves. Complete electrostatic bonding and grounding. Route vent pipes to a safe elevated position, and keep piping short with fewer bends to reduce cold loss.

3. Purging, Pressure Test & Commissioning

After piping, purge the pipeline with high-purity nitrogen to remove welding slag and residual moisture. Carry out air tightness hold test to confirm zero leakage.

Slowly pre-cool the tank during the first filling. Calibrate working pressure, safety valves and emergency cut-off functions, and provide on-site safety training for operators. Complete inspection by authorized institutions, obtain registration documents and file all records before official operation.

4. Common Installation Mistakes to Avoid

• Poor foundation leading to pipeline fracture from settlement

• Ordinary gaskets that become brittle and leak under low temperature

• Low vent outlets causing oxygen deficiency from accumulated cold gas

• Skipping nitrogen purging, resulting in ice blockage inside valves

• Operating without filing and inspection of special pressure vessels
