API standard 650 partially anchored liquid-storage tanks stainless steel armored hose

Before the start of erection, inspect each API 650 tank foundation to ensure that it is level and acceptable to receive Work. Remove temporary erection attachments welded to the interior or exterior of the API standard 650 partially anchored liquid-storage tanks shell or to the bottom by arc gouging, and grind weld area smooth.

The trend of international shipping development of large-scale ships and strategic joint ventures puts forward higher requirements for modern ports. Modern ports no longer use the general cargo throughput as a measure sign, and container throughput will become the main sign to measure the role and status of modern ports. The average container capacity in 2000 is 3200teu, and it is expected to be 5500teu in 2020.

Impact Tests for High Alloys
Impact tests are not required for the high-alloy (austenitic stainless steel) API standard 650 partially anchored liquid-storage 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.

The structure of the API standard 650 partially anchored liquid-storage tanks foundation mainly includes the insulating anticorrosion layer on the top surface of the foundation, the tank wall support, the edge retaining structure, the sand cushion, the oil and water barrier, the detection signal tube and other structures. The construction materials and requirements of each basic structure of the storage tank are different. After the structure of the API standard 650 partially anchored liquid-storage tanks foundation is built in accordance with the construction requirements, the settlement of the storage tank foundation needs to be observed, and the uneven settlement value of the storage tank foundation should be within the allowable safety range.
