摘要
基于LNG薄膜罐结构,阐述薄膜罐的主要施工工艺(外罐内壁基层处理、防潮层施工、水压试验、保冷层安装、密闭层薄膜波纹板焊接、气密性试验)及施工过程控制要点。
Based on the structure of LNG membrane tanks,the main construction technology(the base treatment of inner wall of outer tank,the construction of moisture-proof layer,the hydraulic test,the installation of cold insulation layer,the welding of membrane corrugated plate of airtight layer and the air tightness test)and the key control points of membrane tanks are elaborated.
