CGA G-6.1 PDF

This publication covers the design, location, installation, operation, and maintenance of large insulated liquid carbon dioxide supply systems located at user sites where each container has a liquid capacity of greater than 1000 lb. Industry often refers to these as bulk systems. The system covered is from the container fill connections to the user’s process piping.

It also contains minimum requirements and recommended practices for the design, construction, installation, operation, and maintenance of such systems.

This publication is intended to serve as a guide for regulatory authorities in writing regulations and to assist designers, inspectors, and other interested parties.

Small, stationary, insulated carbon dioxide systems with containers having individual capacities of 1000 lb or less and designed, manufactured, and certified in accordance with ASME Boiler & Pressure Vessel Code, Section VIII, Division 1 requirements are not covered by this publication, refer to CGA G-6.5, Standard for Small Stationary Insulated Carbon Dioxide Supply Systems.

Stationary, uninsulated carbon dioxide systems are outside the scope of this publication.

NOTE—Many of the provisions and design philosophies in this publication apply to storage units in production and depot service. However, the operation, operating conditions, and control systems of those units may require further engineering, controls and safety equipment than required by storage units at a user site.
