Maximum design temperature of API standard 650 self-anchored tanks

The engineering quality of API standard 650 self-anchored tanks not only affects production and operation, but also affects the life safety of the staff. The factors affecting the API standard 650 self-anchored tanks construction quality are all aspects, any link, any part of the problem will affect the whole project, so the quality management is paid more and more attention. How to ensure the engineering construction quality of oil tank? First, make API standard 650 self-anchored tanks construction technical preparation carefully, understand the design intent, master the construction acceptance specification, and make detailed construction technical disclosure to the construction team.

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 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.

The inner layer of API 650 tank is the same as that of single layer tank. It is made of high-quality steel plate in strict accordance with the standard of "steel welded atmospheric pressure vessel". The thickness of API standard 650 self-anchored tanks steel plate reaches the standard and the service life is longer.
