API Std 650 low-alloy steel tanks cover plates

API 650 petroleum storage tank body design is mainly the design of tank bottom, API Std 650 low-alloy steel tanks tank top and tank wall, and the design of tank wall is particularly important. As the main pressure bearing part of API 650 petroleum storage tank, the tank wall bears loads including liquid pressure, wind pressure, seismic load, opening stress, etc. The calculation of such loads is explained in detail in various API Std 650 low-alloy steel tanks storage tank design standards. But in addition, the API 650 petroleum storage tank wall also bears the push-pull force and torque of the connected pipeline.

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 low-alloy steel 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.

Oil storage tank is an important equipment commonly used in petroleum and petrochemical industry. New API Std 650 low-alloy steel 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 low-alloy steel 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.
