A285 grade C plates API standard 650 liquid-storage tanks

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

API 650 storage tank is used for commonly used oil, gasoline, diesel, chemical and production water storage. API standard 650 liquid-storage tanks Storage tanks built to these standards are spread across U.S. refineries, terminals, pipelines, and production facilities. The API 650 detailed standard specifies the design, processing, welding, inspection and installation procedures for storage tanks.

We supply 5800 tons A53 Gr B ERW pipes to Qatar for Qatar Integrated Railway Project - Green Line. This is the first Metro Line in Qatar, and it is located in Doha. We got the order by tender, launched by the Qatar Railways Company for designing, construction and completion of Green Line Project. Before putting order, a delegation from the API standard 650 liquid-storage tanks project side visited us and several other famous steel pipe mills in China for 15 days. Finally, we were chosen and finished the task exceeding their expectations.

The engineering quality of API standard 650 liquid-storage tanks not only affects production and operation, but also affects the life safety of the staff. The factors affecting the API standard 650 liquid-storage tanks construction quality are all aspects, any link, any part of the problem will affect the whole project, so the quality management is paid more and more attention. How to ensure the engineering construction quality of oil tank? First, make API standard 650 liquid-storage tanks construction technical preparation carefully, understand the design intent, master the construction acceptance specification, and make detailed construction technical disclosure to the construction team.
