API 650 floating-roof tanks connections with adjacent structures
When the anchorage is designed to meet the requirements of API Standard 620 tank Q.3.6.4.2, the foundation should be designed to resist the uplift that results from three times the design pressure with the tank full to the design liquid level. When designing to any of the conditions in this paragraph, it is permissible to utilize friction between the soil and the vertical face of the ringwall and all of the effective liquid weight.
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 floating-roof 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.
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 650 floating-roof tanks material, heat number, supplier name and size will be shown on the surface of steel pipe.
}The main types of metal storage tanks are vertical dome roof tank, vertical external floating roof tank, vertical inner floating roof tank, spherical oil tank and horizontal oil storage tank. API 650 floating-roof tanks is vertical tank. The capacity of vertical dome roof oil storage tank is generally less than 10000 cubic meters. The wall plate adopts sleeve type fillet weld, and it is usually installed by inverted or forward installation method during construction.
Due to other non-steel quality reasons caused by the customer dissatisfaction, to timely explain to the customer, and help them solve the problem, for the customer really because of their own reasons, to give patient reply.The process of objection handling is the process of our technical service.
