40ft diameter API Std 650 uplifting tanks

API Std 650 uplifting 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 Std 650 uplifting 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 the high-alloy (austenitic stainless steel) API Std 650 uplifting tanks base materials, nickel alloy based materials, aluminum base materials, and weld deposited for the nonferrous (aluminum) materials. Impact tests are not required for austenitic stainless steel welds deposited by all the welding processes for services of –200°F and above. Austenitic stainless steel welds deposited for service below –200°F by all welding processes shall be impact tested in accordance with Q.6.2 except that the required impact values shall be 75% of the values as given in Q.2.2.2, Item c.

API 650 vertical tanks meet American Petroleum Industries (API) standards in design, material, fabrication, and testing of aboveground welded steel API Std 650 uplifting tanksstorage tanks for use in industrial applications.
