5050 aluminum tube API standard 650 mixed material tanks

Our company will set up a full-time service engineer for the project, who is responsible for the interface and coordination of technical support and after-sales service of the API standard 650 mixed material tanks project. In response process of customer service center, in case of technical support and after-sales service demand, the user shall contact the full-time engineer of API standard 650 mixed material tanks customer service center, and the technical personnel will give corresponding answers and on-site treatment according to the needs of users.

The factors that affect the "small breathing" loss of API standard 650 mixed material tanks are: 1. Generally, the larger the storage tank is, the larger the total open area is, the larger the evaporation area is, and the greater the "small breathing" loss is; conversely, the smaller the storage tank is, the smaller the evaporation area is and the smaller the "small breathing" loss is. 2. It is related to the atmosphere. The lower the atmospheric pressure is, the greater the "small breathing" loss is; otherwise, the loss is reduced.

Impact Tests for High Alloys
Impact tests are not required for the high-alloy (austenitic stainless steel) API standard 650 mixed material 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.
