API 650 storage tanks carbon steel anchor straps

Charpy V-notch specimens shall be taken from the weld metal and from the heat-affected zone of the welding procedure qualification test plates or from duplicate test plates.
Weld metal impact specimens shall be taken across the weld with the notch in the API 620 oil tank material weld metal. The specimen shall be oriented so that the notch is normal to the surface of the material. One face of the specimen shall be substantially parallel to and within 1/16 in. of the surface.

Fixed roof API 650 oil storage tank includes inner floating roof tank, which API 650 storage tanks can effectively prevent sand, rain, snow or dust from polluting the storage liquid.

Generally speaking, the duration of the "exhalation" of the API 650 storage tanks is longer than that of the "inhalation" of the API 650 storage 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 650 storage tanks location, open area of the API 650 storage tanks, atmospheric pressure, filling degree of API 650 storage tanks, etc. When the API 650 storage 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.
