API standard 650 unanchored liquid-storage tanks dead load
The seismic effects on the tank wall of API 650 oil storage tank include the inertia moment generated by the weight of the API standard 650 unanchored liquid-storage tanks tank and the hydrodynamic pressure of the reservoir, which can be divided into short period pulse pressure and long period fluid slopping convective pressure.
In the actual welding of API standard 650 unanchored liquid-storage tanks, operators will use more arc-shaped plates for tailor-welding to better adapt to the larger volume of oil storage tanks. In order to effectively control the deformation of the welding seam of the API standard 650 unanchored liquid-storage tanks, a scientific and accurate prefabricated bottom plate is required. In the process of prefabricating the bottom plate of the oil storage tank, it is necessary to strictly follow the technical requirements for the construction of the oil storage tank. At the same time, it is also necessary to clarify the external dimensions according to its actual manufacturing standards so that it has sufficient shrinkage.
Butt-welded joints used to fabricate large steel storage tank fittings shall be completely radiographed. Lines carrying liquid shall be hydrostatically or pneumatically pressurized at a minimum pressure of 35 lbf/in.2 and API standard 650 unanchored liquid-storage tanks butt welded joints shall be simultaneously visually examined (hydrostatic) or solution film tested (pneumatic) for tightness. If manufactured pipe has been hydrostatically tested previously to ASTM requirements, then only circumferential welds need to be examined.
Our technical department plays important role in our professional communication with customers, especially those who have high technical requirements for steel materials and those who need complex further processing.

The profession of our team has won great praise of customers.
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.
