API 650 welded steel oil storage tanks centerline-stacked

The outer layer of API 650 tank is glass fiber reinforced plastic layer with a thickness of more than 2.5mm, which API 650 welded steel oil storage tanks has strong corrosion resistance and electric corrosion resistance. Special process technology is used between the two layers to make the gap reach 0.1 mm, so as to eliminate the existence of potential safety hazard from the root.

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 650 welded steel oil 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.

API 620 Crude Oil Tank Pneumatic Pressure
An air pressure equal to 1.25 times the pressure for which the vapor space is designed shall be applied to the enclosed space above the water level. In the case of a double-wall tank with an open-top inner tank, where the air pressure acts against the outer tank and the inner tank is thus not stressed by the air pressure, the inner API 650 welded steel oil storage tanks may be emptied of water before the pneumatic pressure test begins. The test pressure shall be held for 1 hour.
