Do atmospheric storage tanks installed on-site require a production license?

Atmospheric pressure equipment (atmospheric pressure vessels) that are manufactured or assembled on-site do not require a pressure vessel manufacturing license! If it is a construction company, it should possess the appropriate construction qualifications, such as first-level or second-level qualifications for petrochemical and mechanical and electrical installation projects.

At-site installed atmospheric pressure storage tanks do not require a production license for pressure vessels； Pressure vessels are special equipment

Atmospheric pressure vessels do not require any formalities, while pressure vessels need to be reported to the boiler inspection agency to go through the necessary registration procedures

In accordance with the definition of pressure vessels in the Regulations on the Safety Supervision of Special Equipment, a pressure vessel is a sealed device used to hold gases or liquids and subject to certain pressure; it includes fixed and mobile containers whose maximum operating pressure is 0.1 MPa (gauge pressure) or higher, and whose product of pressure and volume is 2.5 MPa·L or higher, for gases, liquefied gases, and liquids whose maximum operating temperature is equal to or higher than their standard boiling point； Gas cylinders, liquefied gas cylinders, and cylinders for liquids with a standard boiling point of 60°C or lower, whose nominal working pressure at full charge is greater than or equal to 0.2 MPa (gauge pressure), and whose product of pressure and volume is greater than or equal to 1.0 MPa·L ； Oxygen chambers, etc. ”Atmospheric pressure vessels fall outside the category of pressure vessels; therefore, they do not require a production license.

Atmospheric pressure vessels are not covered by the scope of pressure vessels as defined in the Regulations on the Safety Supervision of Special Equipment; therefore, such vessels do not require a production license. But it can be manufactured in accordance with the pressure vessel manufacturing regulations.

The installation of pressure vessels at normal pressure does not require a license; however, if pressure vessels are to be installed, a special equipment installation license is needed, and the local safety supervision authority must be informed.

Production license? It should be a production facility that requires such procedures. Pressure vessels require a special equipment use license.

It is not clearly stated in the \"Detailed Rules for the Production License of Packaging Materials and Containers for Hazardous Chemicals\", but the \"Notice on Supplementary Revisions to the Detailed Rules for the Production License of Packaging Materials and Containers for Hazardous Chemicals\" contains the following provision: Storage tanks do not include buried oil tanks at gas stations, above-ground storage tanks in oil depots (including gas stations), storage tanks in reaction units, and large-scale storage tanks that require on-site manufacturing and installation. ” I would like to express my gratitude to the friends upstairs!
