Nominal diameter of API standard 650 aluminum storage tanks

These API 650 documents will define the bases of design, operation, inspection, tests, examinations, and maintenance of an API standard 650 aluminum storage 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 aluminum storage tanks foam generator is a fire extinguishing device fixed on the oil tank. One end of the foam generator is connected to the foam pipeline, and one end is flanged on the top layer of the API standard 650 aluminum storage tanks wall. Fire extinguishing foam flows through the air intake entrance of the fire foam chamber, inhaling a large amount of air to form foam, and breaking through the insulating glass into the tank (glass thickness is not greater than 2mm), so as to achieve the purpose of fire fighting.

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%.
