ASTM A216 grade WCB external floating roofs API standard 650 closed top welded storage tanks
The thickness of the API standard 650 closed top welded 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.
Storage tanks API standard 650 closed top welded storage tanks built to these standards are spread across U.S. refineries, terminals, pipelines, and production facilities. The API 650 petroleum storage tank detailed standard specifies the design, processing, welding, inspection and installation procedures of the storage tank.
In 2015, we participated in an tender for oil and casing pipe in Pakistan. Because of our professional service and company strength. The end user chose us as the final contractor of the project of 22000 meters pipes of different sizes production. It takes us about 3 months to produce all the pipes API standard 650 closed top welded storage tanks . We use bulk vessel to ship the pipe to Karachi port. Our engineers went to Karachi port to inspect the condition along with the customer when ship arrive. The customer gave high appraise to the pipe quality and our service
}Strictly controlling the temperature in the API standard 650 closed top welded storage tanks can effectively reduce the volatile consumption of oil in large oil storage tanks. Because the higher the temperature in the oil storage tank, the stronger the activity of oil molecules and the greater the volatilization consumption of the oil. Therefore, the temperature in the API standard 650 closed top welded storage tanks must be reduced as much as possible. It is possible to reduce the direct sunlight temperature by painting white anticorrosive paint with good light reflectivity. It is also possible to use spray equipment to wash the top and wall of the API standard 650 closed top welded storage tanks with water flow to reduce the volatilization consumption of the oil in the storage tank.
Relying on the background of high-quality steel resources and its own strong steel machining capabilities, BBN comany can not only supply various steel material products, such as steel coils, steel plates, API standard 650 closed top welded storage tanks sheet, steel pipes, and shaped steels, but also provide a variety of steel deep processing services like cutting, welding and grinding. Through continuous technological innovation and after-sales service optimization, the company has its own world on the domestic and international steel industry stage!
