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.Soil Structure Interaction: Soil structure interaction per API 650, Section E.6.1.6 may be used for OLE design providing the damping ratio does not exceed 10 %.
Allowable Stresses
Design allowable stresses shall be per API 620 large welded steel storage tank, Section Q.3.3, including the 33 % increase permitted for earthquake loads.
Self-anchored Inner Tank
The anchorage ratio for a self-anchored inner tank, J, shall not exceed 1.0 for the OLE design combination to limit uplift and stresses in the annular plate and corner weld.
Foundation Stability
The overturning ratio defined in API 650, Section E.6.2.3, Equation (E.6.2.3-1) shall be equal to or greater than 3.0 for the defined OLE event.API 650 Application As described by the American Petroleum Institute, the fabrication and installation of our surface welded API Std 650 petroleum storage tanks steel storage tanks is normally used in industrial applications. In general, our standards for industrial on-site installation of storage tanks are established according to API 650, API 620 and API 12D.Company through its own API Std 650 petroleum storage tanks website, multimedia, radio, newspapers, the group, the handbook of the corporate culture carrier, approved and publicity column, in-depth to carry out enterprise culture construction, also through photography, painting, calligraphy, cartoon, speech, and the songs of the enterprise design, various cultural and sports activities to carry out enterprise culture construction.High temperature heat transfer oil fin tube heating device for large API Std 650 petroleum storage tanks has the advantage of reducing the leakage of heating coils. The heating medium of the large storage tank heating device is high-temperature heat-conducting oil. The boiling point of the heat-conducting oil is high, usually higher than 200°C. At high temperatures, the pressure on the heat-conducting oil circulation pipeline is very small, which greatly reduces the occurrence of heating coil leakage accidents. At the same time, the temperature difference between the inside and outside of the tube is guaranteed.
