API standard 650 unanchored liquid-storage tanks hydrostatic testing requirements

In the event of continuous heavy rainfall, the inspection of the API standard 650 unanchored liquid-storage tanks farm should be strengthened to monitor and pay close attention to the soil moisture content of the tank farm in order to quickly take emergency measures. Check whether the seals of the oil unloading port and the oil measuring port are in good condition in time to prevent rainwater from leaking into the API standard 650 unanchored liquid-storage tanks from the oil unloading port and the oil measuring port, which will affect the oil quality.

This API 650 tank standard is designed to provide industry with tanks of adequate safety and reasonable economy for use in the API standard 650 unanchored liquid-storage tanks storage of petroleum, petroleum products. and other liquid products.

In particular, the EU imports a large amount of iron ore from central and South America and Oceania, which are mainly transported by sea. The perfect port infrastructure makes the port operation cost of EU iron ore raw materials import relatively low. However, the API standard 650 unanchored liquid-storage tanks steel transportation between EU Member States is mainly railway transportation, and the EU member states have established a very developed railway network and railway information infrastructure.

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