API 650 self-anchored tank terms and definitions

API 650 petroleum storage tank pipeline stress and product pressure, tank pressure, uniform or non-uniform temperature difference between the tank wall and the tank bottom, which cause the radial displacement and longitudinal rotation of the API 650 self-anchored tank tank wall at the opening to affect the oil tank wall The impact is obvious. Therefore, the design must ensure that the load applied by the external pipeline on the opening of the tank wall is within the safety limit. If the stress of the API 650 self-anchored tank connecting piping is not handled properly, the wall of the API 650 petroleum storage tank may deform or even rupture, causing a major accident.

API 650 self-anchored tank construction must adhere to the design drawings, acceptance specifications and construction plans. If the design needs to be modified during API 650 self-anchored tank construction, it must be approved by the original design unit or Party A’s representative and relevant personnel of the supervision unit, and written visa procedures must be completed in advance. The equipment and main materials used in the oil tank construction project must have certificates of conformity and quality assurance.

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 650 self-anchored tank 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.

The technology center has always been focusing on application research, improving market realization and scientific and technological contribution rate; taking user demand as the goal, highlighting the personalized development of products; taking the joint development of industry, University and research, and technology integration as the means, improving the starting point and level of innovation, and realizing the breakthrough of core technology; taking advanced research as the guide, pursuing the leap of technological development; taking system and mechanism innovation as the driving force, Promote and realize the working concept of technological innovation.

In particular, the EU imports a large amount of iron ore from central and South America and Oceania, which are mainly transported by sea. The perfect port infrastructure makes the port operation cost of EU iron ore raw materials import relatively low. However, the API 650 self-anchored tank steel transportation between EU Member States is mainly railway transportation, and the EU member states have established a very developed railway network and railway information infrastructure.
