Steel pipe materials for API standard 650 cylindrical tanks

These API 650 documents will define the bases of design, operation, inspection, tests, examinations, and maintenance of an API standard 650 cylindrical tanks industrial facility. Bidders will study and analyze all this API 650 documentation, both during the preparation of the quotation and during the execution of each project activity.

API standard 650 cylindrical tanks Drain hole: The drain hole is generally installed at the bottom of the oil tank, used to remove sludge when cleaning the oil tank, and usually used to drain the sewage in the tank. API standard 650 cylindrical tanks Safety valve: The role of the safety valve is to play a safety role when the breathing valve fails during the operation of the oil tank. Its working pressure is slightly higher than the pressure of the breathing valve, which can prevent the tank from being damaged due to the high positive or negative pressure in the tank. The safety valve is usually installed in the middle of the API standard 650 cylindrical tanks top.

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 cylindrical 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.
