A333 grade 1 pipe API 650 SUG III tanks

BBN employees work hard and work hard in their work. In life, colleagues care about each other, like a family, and accompany each other at important moments in life. BBN Steel organizes employees to carry out tourism activities every year, so that families can be exposed to nature and relax physically and mentally. The good combination of working and rest can achieve the goal of hard work and happy life.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 SUG III 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.Under the action of the earthquake, API 650 storage tank is mainly damaged by the phenomenon of the lower part of the API 650 SUG III tanks tank wall. Therefore, the key point of seismic calculation is to prevent the tank wall from buckling under axial pressure."Adhere to green development, implement basic national policies to conserve resources and protect the environment, and take the goal of creating a resource-saving and environment-friendly iron and steel joint enterprise to promote the construction of ecological civilization.Strengthen the construction of core talents, further release the talents' innovative wisdom and innovation potential, and promote the efficient and high-quality development of enterprises. Adhere to the people-oriented principle, persist in relying on employees for development, share development results with employees, and build a harmonious enterprise."Usually, the wind load in the API 650 SUG III tanks construction area should be considered before the tank design and construction. The wind load in the API 650 SUG III tanks construction area has an impact on the stability and economy of the API 650 SUG III tanks. In the area with large wind load, it is safe to design the tank as "squat". When calculating the wind force, the influence of the thickness of the insulation layer of the API 650 SUG III tanks, the shape of the ladder, the platform, the pipeline and the top cover must be considered.
