5454 aluminum plate API Std 650 SUG II tanks
API 650 petroleum storage tank has the advantage of long economic life: because there is no gas space on the liquid surface in the internal floating roof API Std 650 SUG II tanks storage tank, the vibration generated during the transportation of liquid inside and outside the tank is reduced.
Under the condition of static storage without receiving and sending operation, the temperature of gas space, evaporation rate, depth and pressure of vapor in the API Std 650 SUG II tanks will change with the change of temperature and pressure in a day. The oil loss caused by the process of discharging oil vapor and inhaling air gas is called "small breathing" loss, which is also called static storage loss of oil tanks.
The thickness of the API Std 650 SUG II tanks annular bottom plates shall be in accordance with Table Q-4 (for steel or aluminum, as applicable). The thicknesses shown are minimums. The ring of annual plates shall have a circular outside circumference, but it may have a regular polygonal shape inside the tank shell with the number of sides equal to the number of annular plates. These pieces shall be butt-welded in accordance with Q.7.1.1, Item b. The plates of the first shell course shall be attached to the annular bottom plates by a weld as required by API 620 oil tank 5.9.5 except when a full-penetration weld is used or required (see Q.7.1.1). Butt-welds in annular plates shall be not closer than 12 in. from any vertical weld.
We have Business Department, Transportation Department, Document Department, Shipping Department, E-C department, Procurement Department, Finance Department, Human Resources Department, Administration Department, Logistics Department, After-sales so on Departments. Each department performs its own duties, unites and cooperates, and contributes its greatest strength to the overall operation of the company. So as to ensure the stable and sustainable development of the company.
The mode of iron and API Std 650 SUG II tanks steel logistics transportation is mainly intercontinental ocean shipping and inland rail transportation. European ports have been very mature after years of development, such as Hamburg in Germany, Rotterdam in the Netherlands and Antwerp in Belgium. Relying on the huge market of the European Union, these ports are positioned in the logistics distribution function of cargo distribution and large import and export, and play a great role in the transportation of API Std 650 SUG II tanks steel logistics.
