　　【1】 Characteristics of liquefied gas

　　Gas is widely used in industrial production and daily life, mainly distributed in gas fields, oil fields, coal seams, and shale formations. Compared with energy sources such as coal and oil, gas combustion does not produce waste residue or wastewater, making it a relatively clean energy source with high calorific value. Therefore, in recent years, more and more people have started using liquefied gas. It can be seen that exploring the application of gas liquefaction technology memory is of great significance.

　　Characteristics of liquefied gas:

　　(1) Convenient for transportation and storage

　　Compared to gaseous gas, liquid gas is easier to transport and store, and there is no loss during storage, thereby increasing the efficiency of liquefied gas use and bringing high convenience to people's lives.

　　(2) High sex

　　We all know that gaseous gas needs to be transported in a high-pressure environment during transportation. However, in high-pressure environments, the transportability of gas is relatively low. Nowadays, the transportation of liquid gas does not need to be completed in a high-pressure environment, so the transportability is higher.

　　(3) In use for cleaning

　　Gas usually undergoes strict pre purification before liquefaction. In this case, there are fewer impurities in the gas used, and compared to gaseous gas, it needs to be clean during use. When using relatively clean gas, the degree of environmental pollution caused by the gas produced after combustion is also lower, thereby reducing air pollution and improving air cleanliness.

　　【2】 Production and installation of tank bottom

　　1. Before laying the bottom plate, a cross centerline should be drawn on the foundation. The middle strip should be laid first according to the layout plan, and then the middle and side plates should be laid on both sides. While laying, they should be aligned and temporarily fixed with fixtures or spot welding. The allowable deviation for the overlap width of the bottom plate is ± 5mm; 2. The type and size of the docking joints between the center plates of the tank bottom and between the center plates and the edge plates should meet the requirements of the design drawings. From the overlap section to the docking point, acetylene flame heating should be used for bending, and the misalignment of the docking should not exceed 1mm; 3. The welding sequence of the LNG storage tank bottom plate is important, and welders are strictly required to follow the following process:; 4. The welding of the middle panel should be done with the short seam before welding the long seam; Before short seam welding of batten, the temporary welding spots between the batten and the batten or edge plates on both sides shall be removed; When welding long seams, the welders should be evenly and symmetrically distributed, welding from the center outward using the segmented backward method; 5. Transform the lap joint at the edge of the bottom plate into a butt joint. During welding, it is advisable to symmetrically distribute the gap and skip weld, leaving a uniform shrinkage joint. The gap between the joints should be filled and welded flat, and the surface of the weld seam should be smooth and even; 6. To reduce welding deformation, the circular fillet weld between the bottom plate and the bottom ring plate should be symmetrically distributed by several pairs of welders inside and outside the LNG storage tank, and welded in sections in the same direction. Alternatively, the welding sequence of welding the inner ring first and then the outer ring can be used; 7. The overlapping weld seam of the edge plate should be welded back in sections from the outside to the inside; 8. Then weld the connection seam between the center plate and the edge plate. Before welding, the weld position between the two plates should be cleaned, and the welder should evenly distribute along the circumference and perform skip welding in sections.
