API standard 650 welded tanks for oil storage centerline-stacked

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 welded tanks for oil storage 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 is used to store products such as crude oil, gasoline, chemicals, and produced water. BBN has extensive experience in API standard 650 welded tanks for oil storage API 650 tanks with diameters between 8'-300', which are suitable for refineries, terminals, pipeline facilities and other projects.

High temperature heat transfer oil fin tube heating device for large API standard 650 welded tanks for oil storage has the advantage of reducing the leakage of heating coils. The heating medium of the large storage tank heating device is high-temperature heat-conducting oil. The boiling point of the heat-conducting oil is high, usually higher than 200°C. At high temperatures, the pressure on the heat-conducting oil circulation pipeline is very small, which greatly reduces the occurrence of heating coil leakage accidents. At the same time, the temperature difference between the inside and outside of the tube is guaranteed.
