This document specifies the symbols for welded insulated gas cylinders (hereinafter referred to as "gas cylinders"), and stipulates the model naming method, basic parameters, materials, design, manufacturing, testing methods, inspection rules, type testing, marking, packaging, transportation, factory data, and data storage requirements for gas cylinders. This document applies to gas cylinders used in normal environmental temperatures (-40 ℃~60 ℃) with a nominal volume range of 10 L~1,000 L for liquid oxygen, liquid nitrogen, and liquid argon, and a nominal volume range of 150 L~1,000 L for liquefied natural gas. The design temperature shall not exceed -196 ℃, and the nominal working pressure shall be 0.2 MPa~3.5 MPa. The gas cylinders for storing liquid carbon dioxide and liquid nitrous oxide can be manufactured and inspected in accordance with this document. Note: All pressures not specified in this document refer to gauge pressure.
