A516 grade 450 plates API standard 650 self-anchored flat-bottom tanks
Generally speaking, the duration of the "exhalation" of the API standard 650 self-anchored flat-bottom tanks is longer than that of the "inhalation" of the API standard 650 self-anchored flat-bottom tanks every day. There are many factors affecting the "small breathing" loss, mainly including the following points: the change of temperature difference between day and night, sunshine time of the API standard 650 self-anchored flat-bottom tanks location, open area of the API standard 650 self-anchored flat-bottom tanks, atmospheric pressure, filling degree of API standard 650 self-anchored flat-bottom tanks, etc. When the API standard 650 self-anchored flat-bottom tanks is full of gas, the space volume is small, and the "small breathing" loss is less; if the space volume is large, the loss is also large.
Heat-affected zone impact specimens shall be taken across the weld and as near the surface of the material as is practicable. The API standard 650 self-anchored flat-bottom tanks material specimens shall be of sufficient length to locate the notch in the heat-affected zone after etching. The notch shall be cut approximately normal to the material surface to include as much heat-affected zone material as possible in the resulting fracture. Impact test specimens shall be cooled to the temperature stated in Q.22.
API 650 tank has the advantages of less load on the floating plate, simple and light structure, and can save the central drainage pipe and rotating floating ladder on the API standard 650 self-anchored flat-bottom tanks floating plate. The materials for easy construction and maintenance and sealing parts can avoid aging due to sunlight.

The strip steel thickness is generally below 6mm, which is convenient for crimping and processing. You should choose the API standard 650 self-anchored flat-bottom tanks, strip steel specifications according to your own purposes. The specifications and materials used for different purposes are different, so you must confirm it before buying. It is best to ask professionals to give advice before purchasing strip steel, and purchase the specifications and types you need according to the corresponding requirements.
