API 650 self-anchored flat-bottom tanks joint penetration

Heat-affected zone impact specimens shall be taken across the weld and as near the surface of the material as is practicable. The API 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.

This standard only applies to API 650 storage tanks API 650 self-anchored flat-bottom tanks with uniform bottom support and non-refrigerated service storage tanks with a maximum design temperature of not more than 93 degrees Celsius (200 degrees Fahrenheit).

FANALCA is the biggest motorcycle factory in Columbia. Meanwhile, it is the only distributor in Colombia for Japanese Honda. We began to cooperate with each other since 2017. We supply SAPH370, SAPH440 and so on automobile steel coils to them. As our products quality is proved to be satisfied during their production, they have been one of our stable customers, and give repeat orders about automobile steel every year.

When the API 650 self-anchored flat-bottom tanks is welded, the weldment should be fixed rigidly. After welding, when the weldment is cooled to normal temperature, the rigid fixation can be removed, which can effectively prevent angular deformation and wave deformation. Although some measures have been taken, the welding deformation of API 650 self-anchored flat-bottom tanks is still unavoidable, so it is necessary to take corrective measures to compensate the deformation. Mechanical correction is to make the parts easy to deform in the welding process by mechanical or other rigid materials to produce simple deformation, so as to restore the state before welding.

Both parties shall confirm the API 650 self-anchored flat-bottom tanks material object and the quality of the products, confirm the reasons for the defects and the quality of the products, and sign the quality inspection agreement. Major quality objections shall be reported to relevant leaders in a timely manner, and shall be discussed and solved with the API 650 self-anchored flat-bottom tanks steel plant.
