API Std 650 cylindrical welded storage tanks roof drain valves

Oil storage tank is an important equipment commonly used in petroleum and petrochemical industry. New API Std 650 cylindrical welded storage tanks, metal storage tank must be tested before it can be put into use or put into storage. The common inspection methods of API Std 650 cylindrical welded storage tanks include radiographic testing, ultrasonic testing, magnetic particle testing and dye penetrant testing. The parts and operation requirements of these testing methods are different, so they should be selected according to the required characteristics.

The hardness of the welds contacting these environments, including the heat-affected zones, shall be considered. The weld metal and adjacent heat-affected zone often contain a zone of hardness that is well in excess of a value of 22 on the Rockwell C scale and could be expected to be more susceptible to cracking than would unwelded metal. Any hardness criteria shall be a matter of agreement between the Purchaser and the API Std 650 cylindrical welded storage tanks manufacturer and shall be based on an evaluation of the expected hydrogen sulfide concentration in the product, the possibility of moisture being present on the inside metal surface, and the strength and hardness characteristics of base metal and weld metal.

Standard API 650 tank calls for calculations based on the specific gravity of the liquid product being stored. This permits the thickness of the steel API Std 650 cylindrical welded storage tanks needed as well as other specifications of how the tank is built to be determined by the weight of the API 650 tank.
