API Std 650 self-anchored flat-bottom steel tanks mixers

The longer the service life of the API Std 650 self-anchored flat-bottom steel tanks, the lower the reliability and the prone to failure. Doing a good job in the maintenance of the metal oil tank can ensure the normal use of the oil tank, reduce the wear of the API Std 650 self-anchored flat-bottom steel tanks body and accessories, and extend the service life of the oil tank. The maintenance of metal oil tanks is mainly to do a good job in the anti-corrosion of the oil tank, the cleaning of the deposits in the API Std 650 self-anchored flat-bottom steel tanks and the overhaul of its accessories. Regularly inspect and maintain the accessories of the oil tank: valves, oil measuring holes, breathing valves, flame arresters, ladders, foam fire extinguishing generators, etc., and make records. If any damage is found, repair them in time.

Impact Tests for High Alloys
Impact tests are not required for oil steel storage material nickel alloy welds made with electrodes/filler metals covered by AWS Specification A5.11 or AWS Specification A5.14, provided the nominal nickel content is 50% or greater, and the weld is deposited by the shielded metal-arc welding (SMAW), gas metal-arc welding (GMAW), gas tungsten-arc welding (GTAW), or plasma-arc welding (PAW) processes. When A5.11/A5.14 specifies the nickel content as a “remainder,” the nickel content shall be determined by summing the maximum specified values of the other elements (use the average specified value for elements with specified ranges) and subtracting from 100%.

The application of API 650 is as stated by the American Petroleum Institute: The production and installation of our ground welded steel API Std 650 self-anchored flat-bottom steel tanks storage tanks are generally used in industry; under normal circumstances, the storage tanks installed on the industrial site in the United States are in accordance with API 650, API 620 and API 12d Standards are established.
