Scope

Main technical content: LNG natural gas, as a clean energy source, is increasingly favored and its proportion in energy supply is rapidly increasing. Due to the fact that the temperature of LNG liquid natural gas is -165°C, the welding quality requirements for full-containment LNG storage tanks are relatively high. During the preparation of this document, extensive and in-depth investigations and studies were conducted on the application of gas metal arc welding to the steel domes and pressure rings of full-containment LNG storage tanks. Referencing relevant international standards and advanced foreign standards, this document was formulated. The main content of this document includes: definitions and terms related to LNG storage tanks and the gas metal arc welding used in them, material acceptance, welding wire use, welding processes, and quality inspection.
