API 650 carbon and low-alloy steel tanks typical foundation types
API 650 petroleum storage tank has the advantages of high safety: the API 650 carbon and low-alloy steel tanksinner floating plate floats on the liquid surface, so that the liquid phase has no evaporation space, which can reduce the evaporation loss by 85% to 90%. At the same time, the API 650 petroleum storage tank blocks the air and liquid storage through the floating disk, which reduces air pollution and reduces the degree of fire risk.
Personnel organization before the construction of the API 650 carbon and low-alloy steel tanks:The company shall select technical personnel, quality inspectors and material personnel with organizational ability and construction management experience to participate in the API 650 carbon and low-alloy steel tanks project construction. The construction personnel shall arrive at the construction site before the designated commencement date, investigate the construction site, build construction facilities, plan the construction steps, and analyze the potential safety hazards during operation.
Standard Hydrostatic and Pneumatic TestsAfter erection is completed and stress relieving, radiographic examinations, or other similar operations, as may be required, are performed, each tank shall satisfactorily pass a series of hydrostatic and pneumatic tests as prescribed in 7.18.2 through 7.18.6. Whenever a solution film is specified in this section to be applied to welding, linseed oil or another equivalent material for disclosing air leakage may be substituted. In freezing weather, linseed oil or a similarly suitable material shall be used.The attachment welding around all openings and their reinforcements in the walls of the API 620 tank shall be examined by the magnetic-particle method both inside and outside the tank API 650 carbon and low-alloy steel tanks. When the underside of a tank bottom rests directly on the tank grade (and is not accessible after erection), such examination of welding on the underside of the bottom and subsequent air testing may be omitted.
The company has five major departments: steel plate production department (including quality inspection team), sales department, market development department, after-sales and logistics department, and finance department. The backbone of steel business from all over the country, with the chairman as the core, integrates self-confidence, independence, passion and responsibility, and strives for excellence! All people share the same belief: "Being a refined steel product line rewards customers, strengthen the steel industry, and realize the corporate dream!
The predecessor of Ningbo port is Ningbo Port Authority. Ningbo port consists of Beilun port, Zhenhai port, Ningbo port, Daxie port and Chuanshan port. It is a multi-functional and comprehensive modern deep-water port integrating inland river port, estuary port and seaport.
