API Std 650 flat-bottom steel tanks flanges

The inner and outer tanks may be decoupled for seismic design of the tank and anchorage and assumed to act independently. However, if the inner and outer tanks API Std 650 flat-bottom steel tanks are supported by a common foundation, the seismic foundation loading shall be calculated using the lesser response modification values for either the inner tank or outer tank for both tanks and a dynamic analysis shall be performed to determine the combined effect.
Allowable Stresses: For Appendix R tanks, design allowable stresses shall be per API 620 large low pressure storage tank, Section R.3.3.

These API 650 documents will define the bases of design, operation, inspection, tests, examinations, and maintenance of an API Std 650 flat-bottom steel tanks industrial facility. Bidders will study and analyze all this API 650 documentation, both during the preparation of the quotation and during the execution of each project activity.

our company supplied 2300 ton API 5L GrB ERW pipe to Petroleum company in 2016. It takes 35 days for our company to finish all the production according to API 5L standard. The products are used to drilling , gas transmission works. And we supply the API5L PSL1 GR B original Mill Test Certificate, API5L PSL1 GR B pipes picture, the dimension test, the API Std 650 flat-bottom steel tanks material, heat number, supplier name and size will be shown on the surface of steel pipe.

Static storage loss is also known as "small breathing" consumption. The rise and fall of the temperature in the API Std 650 flat-bottom steel tanks leads to the increase and decrease of the pressure in the tank, which makes the mixed oil gas discharged from the tank, and the external air is sucked into the tank, resulting in the oil consumption. Fluid level loss is also called "big breathing" loss. It is the oil consumption caused by the change of gas space volume in the API Std 650 flat-bottom steel tanks during the oil receiving and sending operation, which causes the mixed oil gas to be discharged out of the tank, and the external air is sucked into the tank, resulting in the oil consumption due to the change of liquid level height.

The company attaches great importance to the cultivation of team spirit. Personal strength is weak. After sales service departments, leaders and subordinates often communicate with each other. Everyone often holds meetings to discuss their problems in after-sales service, discuss technical difficulties, discuss how to improve work efficiency, how to better deal with user complaints, etc.
