Cryogenic liquid storage tanks for liquid nitrogen, liquid oxygen, liquid argon, and liquid carbon dioxide require professional removal services after long-term operation due to equipment renewal, site adjustment, production upgrading, or scrapping demands.

Cryogenic liquid storage tanks for liquid nitrogen, liquid oxygen, liquid argon, and liquid carbon dioxide require professional removal services after long-term operation due to equipment renewal, site adjustment, production upgrading, or scrapping demands. As special pressure vessels, cryogenic tank removal involves high-risk procedures including residual liquid disposal, pressure relief, explosion prevention, and leakage control. All operations must be carried out by qualified professional teams to eliminate potential safety hazards. Recently, our professional construction team successfully completed a cryogenic liquid tank removal project for the client. The whole process was safe, efficient and fully compliant, solving the client’s old equipment disposal problems and strengthening the safety barrier for industrial construction.

Adequate preparation is the core of safe cryogenic tank removal. Before construction, our team strictly complies with the Supervision Regulation on Safety Technology for Pressure Vessels. We thoroughly drain the residual cryogenic liquid inside the tank and conduct multiple nitrogen purging treatments on the tank and pipelines to eliminate residual media and flammable gas risks. Oxygen concentration and flammable gas density are strictly tested and confirmed to meet safety standards before construction entry. After on-site investigation, we formulate a dedicated removal plan, mark safety operation zones, equip explosion-proof devices, anti-freezing protective gear and fire-fighting equipment, complete special operation approval, and conduct full-process safety technical disclosure to ensure zero construction errors.

The removal process strictly follows the standardized principle of "accessories first, main body later; light components first, heavy components later, and segmented operation". We first disassemble and classify tank accessories including valves, instruments, pipelines and safety valves. Then we remove the outer thermal insulation layer to avoid hidden dangers caused by falling insulation materials. Finally, professional cutting equipment is adopted for segmented tank dismantling, with large hoisting equipment for stable transportation. The whole process strictly controls open flames and static electricity, preventing tank collision and dumping to protect surrounding equipment and on-site environment.

Cryogenic tank removal is a high-risk special operation. Unprofessional construction may easily cause frostbite, liquid leakage, explosion and other accidents. With years of experience in the cryogenic gas industry, our company holds complete construction qualifications, employs certified technical teams and implements a rigorous safety management system. We have completed hundreds of tank removal projects with zero safety accidents. All construction processes comply with environmental protection standards, with standardized residual liquid recovery and waste classification, ensuring efficient construction without affecting the client’s normal production.

Safety and standardization are the top priorities of cryogenic tank removal. We provide one-stop services including cryogenic tank installation, inspection, maintenance and removal. With professional technology, standardized procedures and strict safety control, we help clients safely dispose of old tanks, avoid construction risks and reduce operational costs.
