API Std 650 self-anchored tanks maximum design temperature

API 650 internal floating roof oil tank executive standard: domestic design standard: GB50341-2003 "Vertical cylindrical steel welded oil tank design code"; domestic construction standard: GB50128-2005 "vertical cylindrical steel welded oil tank" Construction and Acceptance Specification; API Std 650 self-anchored tanks Foreign design standard: API650-2007 "Standard for Welded Steel Petroleum storage tanks."

The head of API Std 650 self-anchored tanks etc. vertical oil tank is the end cover on the top of vertical oil tank. It is used to separate the oil stored in the tank and the medium outside the tank, and also used to bear the pressure on the top of the vertical oil tank. The quality of the head is closely related to the long-term safety of the API Std 650 self-anchored tanks. The head surface can be divided into convex shape, cone shape and flat shape according to its shape. The oil tank head can not be disassembled after welding.

Insulation Load
For API 620 tanks designed and constructed with an outer tank containing loose fill insulation in the annular space between the tanks, the insulation weight shall be divided equally to the inner and outer tank wall for seismic lateral loads unless a more rigorous analysis is performed to determine the distribution. The insulation within the annular space shall not be used to calculate resistance to overturning. Insulation on the API Std 650 self-anchored tanks roof or suspended deck shall be applied to the tank supporting the load at the point or center of gravity of attachment and may be used to resist overturning.

When talking about our team, it is hard not to mention our QC department (Quality Control). We have built strict qualitycontrol system to guarantee the steel quality. During the steel materials production, we have strict monitoring measures and indicators, and ensure no chemical composition, mechnical properties and so on technical problems for the steel materials API Std 650 self-anchored tanks. After production, our QC department will conduct another inspection regarding to the steel quantity, dimension, mark and so on points before delivery.

As a leading international steel supplier, we have two warehouses, close to Tianjin port and Shanghai port. This superior geographical location effectively saves the domestic transportation cost and greatly improves our service level. At the same time, it also shortens our delivery time and provides more convenience for customers.
