API standard 650 ground-supported liquid storage tanks metal-seated ball valve
Tanks which are designed following rules and guidelines of API 650 are API 650 tanks. API 650 API standard 650 ground-supported liquid storage tanks is the governing code for Welded tanks for Oil storage normally operating in the atmospheric pressure range. The code API 650 provides guidelines for design, fabrication, material, erection, and inspection of welded vertical and cylindrical storage tanks. Such API standard 650 ground-supported liquid storage tanks Tanks must be above ground with a closed or open top.
X-ray inspection is mainly applicable to the internal inspection of pressure bearing parts and materials of metal oil tanks such as API standard 650 ground-supported liquid storage tanks. It can clearly find the blocky defects inside the welded joints. However, the cost and resource consumption of radiographic testing are large. Magnetic particle testing can effectively detect the surface and near surface defects of API standard 650 ground-supported liquid storage tanks etc. metal oil tanks, but magnetic particle testing can not effectively identify the internal defects of oil tanks.
The thickness of the API standard 650 ground-supported liquid storage 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.
The quality inspection department is responsible for the inspection management of raw materials and finished products, and the quality inspection and acceptance of products and raw materials. Strictly abide by the company's management system, conscientiously exercise the management power given by the company, and put an end to all ultra vires; be responsible for the inspection of all kinds of raw materials entering the company, and put forward quality problems and handling opinions.
Iron and steel goods, including pig iron, ingots, all kinds of steel and so on. Therefore, logistics companies are required to load evenly and evenly in the process of transportation, prevent moisture and prevent corrosion. It is necessary to prevent the API standard 650 ground-supported liquid storage tanks steel sheet from being mixed with water when transporting the steel; it is necessary to prevent the API standard 650 ground-supported liquid storage tanks steel from being mixed with water when transporting the steel; it is necessary to prevent the steel from being mixed with water when transporting the steel; it is necessary to prevent the steel from being mixed with water when transporting the steel; it is necessary to prevent the steel from being mixed with water when loading the API standard 650 ground-supported liquid storage tanks steel sheet on the truck Good luck.
