API standard 650 anchored liquid-storage tanks with a self-supporting roof
API 650 petroleum storage tank stipulates that if the thickness of the lower siding obtained by calculating the anti-overturning moment is greater than the thickness of the API standard 650 anchored liquid-storage tanks hydrostatic pressure test (both do not include the corrosion margin), the calculated thickness of the above siding required by the hydrostatic pressure is It should also be increased by the same proportion, unless special analysis is performed to determine the seismic overturning moment and corresponding stress at the bottom of each layer of API 650 petroleum storage tank wall.
The hot weather in summer brings great security challenges to the vertical oil storage tanks, API standard 650 anchored liquid-storage tanks standing outdoors. We must find some simple and effective methods to protect the API standard 650 anchored liquid-storage tanks in order to make them safely spend the summer. As a API standard 650 anchored liquid-storage tanks manufacturer, in order to reduce the direct sunlight rate of the vertical oil tank, reduce the temperature change of the oil tank, and reduce the evaporation loss of the oil tank, we usually adopt the measures of applying sunscreen paint and washing with warm water.
Manufacturer’s Report and CertificateUpon completion of all tests and inspections on each tank API standard 650 anchored liquid-storage tanks, the Manufacturer shall prepare a report summarizing all the data on the tank, including foundations (if they are within the Manufacturer’s scope of responsibility) and shall attach to the report all drawings and charts as required by other paragraphs in this section of the rules (see API 620 tank 7.13 and Appendix M).The tank Manufacturer shall furnish and fill out a certificate for each tank (such as that shown in Appendix M), attesting that the tank has been constructed according to the rules in this standard. This certificate shall be signed by the Manufacturer and the Purchaser’s inspector. This certificate, together with the nameplate or markings placed on the tank, shall guarantee that the Manufacturer has complied with all applicable requirements of these rules.
Our quality control department will do inspection for details of the steel materials API standard 650 anchored liquid-storage tanks before delivery. We would invite the customer side to attend the inspection together. If they can not come, we will also take rich pictures for them to check. Meanwhile, we will publish inspection report and send them the PDF version. Besides, we accept any third party inspection such as SGS, BV, etc. And our quality control department will support the third party to inspect the steel materials smoothly and try our best to deliver the qualified steel materials to customers earlier.
Japan is a typical shipping first, and its raw materials are imported from Oceania, central and South America and other Asian countries. Most of the API standard 650 anchored liquid-storage tanks steel produced is exported to China and other Asian countries, and a small amount is exported to America. Shipping is the main way of its API standard 650 anchored liquid-storage tanks steel international transportation. According to the data, steel goods account for about 20% of the total sea freight in Japan. The domestic transportation of Japanese steel is mainly truck.
