EN S355J2 plates API 650 open top welded storage tanks
The advantages of API 650 floating roof tanks have obvious environmental and economic benefits: in a specific climate environment, according to historical data, the economic value of the API 650 open top welded storage tanks floating roof tanks in API 650 due to the reduction of oil and gas volatilization within 3-6 months is equivalent The installation and purchase cost of the API 650 open top welded storage tanks inner floating roof means that the cost of the inner floating roof can be recovered within half a year.
Welders participating in the construction of API 650 open top welded storage tanks must pass the examination and perform welding within the validity period of the qualified items. Special operators such as on-site maintenance electricians, cranes, and shelf workers must hold job certificates. All oil pipelines need to use arc welding for bottoming and electric welding to ensure the welding quality. Oil tanks and process pipelines must be tested for non-destructive flaws in accordance with the flaw detection ratios and methods required by the design and acceptance specifications. The flaw detectors must be certified.
The thickness of the API 650 open 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.
