[0002] Liquefied gas cylinders are steel containers used to store compressed liquefied gas. They are usually made of high-strength steel and have the characteristics of pressure resistance, corrosion resistance, and good sealing. Liquefied gas cylinders are widely used in households, commercial and industrial fields to store liquefied petroleum gas, liquefied natural gas, liquefied coal gas and other gases, and supply them to various gas equipment. In order to ensure safety, liquefied gas cylinders need to undergo strict testing and quality control to ensure their safety and reliability during storage and use;
