The highest design temperature of API 650 larger diameter tanks

This API 650 tank standard does not present orstablish a fixed series of allowable tank sizes: instead, it s intended to permit the purchaser to select whatever size API 650 larger diameter tanks tank may best meet his needs.

Strictly control the welding groove forming of API 650 larger diameter tanks: in order to ensure the geometric dimension of assembly and good welding of welding seam, before hoisting and laying, the edge of all metal vertical storage tank plate shall be polished by grinder, and the flatness of plate shall be ensured according to the design requirements. Strictly control the size of API 650 larger diameter tanks weld assembly: measures must be taken to strictly control the assembly size of metal vertical tank bottom plate during assembly.

The tank shall be filled with water to the design liquid level unless height is limited as noted in API 620 standard Q.8.1. After the tank is filled with water and before the pneumatic pressure is applied, anchorage, if provided, shall be tightened against the hold-down brackets. All welds in the API 650 larger diameter tanks shell, including the corner weld between the shell and the bottom, shall be visually checked for tightness.

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 larger diameter 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.
