Design and construction of foundations for API Std 650 aboveground oil storage tanks

The API 620 large storage tank nozzle neck is fabricated by welding from 1/2-in. plate. The materials in the tank wall, the nozzle neck, and the reinforcing pad conform to ASTM A442 Grade 55. The main joints in the tank wall are fully radiographed, double-welded butt joints. The longitudinal joint in the nozzle neck is of the same type API Std 650 aboveground oil storage tanks but is not radiographed; however, the longitudinal joint and all other parts of the nozzle-and-wall-plate assembly have been shop stress relieved after fabrication, as required by 5.25. The adequacy of the reinforcement and attachment welds shown in Figure F-6 shall be determined.

There is a gap of 100 mm to 500 mm between the shell of API 650 crude oil storage API Std 650 aboveground oil storage tanks tank and the floating plate of external floating roof to ensure that there is no chuck during operation. Use API Std 650 aboveground oil storage tanks edge sealing system to reduce edge evaporation. The support legs of API 650 crude oil tank floating roof are usually movable and retractable and suspended in liquid.

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 aboveground oil storage tanks material, heat number, supplier name and size will be shown on the surface of steel pipe.

Unqualified welding quality of API Std 650 aboveground oil storage tanks is prone to hidden dangers such as oil tank steel plate cracks and leakage. To avoid this situation as much as possible, it needs to be avoided when the oil storage tank is manufactured. Scientific and reasonable measures are adopted to control the welding quality when welding the API Std 650 aboveground oil storage tanks. How to reasonably control the welding process quality of oil storage tanks?

After-sales service is an important part of measuring a product good or not. After sales service can't be ignored. Good service can really make consumers feel relieved. We have always done a good job in after-sales service, so as to bring consumers a better reference when purchasing and a better experience during use of our steel materials. We will call back and follow up the performance of our steel products regularly.
