5154 aluminum tube API 650 cylindrical liquid-storage tank
The thickness of the API 650 cylindrical liquid-storage tank 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.
API 650 tanks in which liquid fluids are stored and designed to withstand atmospheric pressure operation, less than 18 kPa, or internal pressures not exceeding the weight of the API 650 cylindrical liquid-storage tank roof, with temperatures no higher than 93, 3 C are included in the scope of this design code.
The Indonesia INKA is the only train carriage maker for railway industry in Indonesia. We cooperated with them since 2012 and supply them SPA-H steel. The SPA-H steel is used by them to fabricate train carriage. We have huge stocks for SPA-H steel and can arrange delivery for them in short time after receiving order. Meanwhile, our product API 650 cylindrical liquid-storage tank quality has passed their test for so many times use. Therefore, they trust us and give us repeat orders regularly. And we also do our best to support them and have never let them down though past cooperations.
}The preparatory work before the construction of the API 650 cylindrical liquid-storage tank is directly related to the quality assurance, project progress, construction safety and other aspects of the entire oil tank project. Therefore, the preparation work before the API 650 cylindrical liquid-storage tank construction should be paid attention to and planned. Before API 650 cylindrical liquid-storage tank construction, you need to prepare conventional machinery, materials, and facilities, as well as the quality control of the project, such as the installation method of the API 650 cylindrical liquid-storage tank, the welding method of the steel plate, and the inspection of the tank material. In addition, there is the most important item, construction safety protection.
