API 650 cylindrical tanks qualification of welding procedures
In the petrochemical industry and other industries, large vertical API 650 cylindrical tanks are often used to store various production raw materials Usually, the medium with high melting point and easy to crystallize at room temperature can be exported and used after heating, which involves the heating of large vertical storage tanks The heating system is an auxiliary facility for heating of large vertical storage tank It is often necessary to design external heating coil or internal heating coil system
Changes in Tank ShapeIf in any of the foregoing tests there is an excessive rise of the bottom of the tank around the boundary of contact with grade, or off its foundations, or if any of the specified conditions of test loading cause other appreciable changes in the shape of the tank, the design shall be reviewed and means shall be provided in the tank for holding the shape within permissible limits under all conditions of loading,API 650 cylindrical tanks. Additional TestsThe tests prescribed in API 620 tank 7.18 are believed to be sufficient for most tanks constructed according to these rules; if, in the opinion of the designer, additional tests are needed to investigate the safety of a tank under certain other conditions of loading, as determined from the design computations, these tests shall be made on the tank involved in addition to the tests specified in this standard.
The tank wall design of API 650 oil storage tank. Since there is no ventilation pipe directly connected with the outside on the top of the API 650 cylindrical tanks tank, the ventilation between the inside and outside of API 650 oil storage tank is realized by the respiration valve. The constant pressure of the respiration valve is 0.3kPa, so the pressure on the top of the tank is 0.3kPa.
We have a stable system and professional human resource management work as the support, from the six aspects of guidance, cohesion, incentive, constraint, radiation and stability, we continue to introduce, modify and train employees from concept to action, and shape employees through constant guidance of common values.
