API 650 cylindrical tanks roof plate
Uplift on FoundationFor API Standard 620 tanks with an internal design pressure less than 1 lbf/in.2 gauge, the uplift shall be taken as the smaller of the maximum uplift values computed under the following conditions:a)The internal design pressure times 1.5 plus the design wind load on the shell and roof.b)The internal design pressure plus 0.25 lbf/in.2 gauge plus the design wind load on the shell and roof.
Fixed roof API 650 oil storage tank includes inner floating roof tank, which API 650 cylindrical tanks can effectively prevent sand, rain, snow or dust from polluting the storage liquid. Under various weather conditions, API 650 oil storage tank can ensure the quality of liquid storage, which is called "all-weather API 650 cylindrical tanks storage tank".
We exported 352 tons SA387GR12CL2 steel plates to Vietnam. The Vietnam customer needed the SA387GR12CL2 steel plates for their tank fabrication project urgently. We are world class steel materials supplier and exporter. Other than regular fresh production, we also keep huge stocks, so as to meet urgent demands of our customers. For the 352 tons SA387GR12CL2 steel API 650 cylindrical tanks plates, we collected from our warehouse and it only took us 3 days to arrange delivery. The customer was really impressed by our rapid shipping and spoke highly of our SA387GR12CL2 steel plates quality after use.
}The most popular standards for API 650 cylindrical tanks are API Std 650, JIS B8501, BS2654, GB50341, etc. The formulas used in each standard are derived from the hoop stress calculation formula of membrane theory. Combined with the stress characteristics of API 650 cylindrical tanks, plus the allowable stress, weld coefficient and additional wall thickness, the wall thickness calculation formula is complete. The allowable stress and weld coefficient are determined according to the material performance characteristics and construction technology level of each country. According to different API 650 cylindrical tanks standards, the calculation results of tank wall thickness are sometimes quite different.
The 365 day service system is implemented, and the business, loading and delivery are handled as usual in holidays and festivals. Actively help users solve difficulties. When users encounter difficulties in handling business, they should actively coordinate with the external solution; if they need to solve the problems internally, they should solve them in a timely manner without prevarication and wrangling. In line with the API 650 cylindrical tanks principle of "fairness, justice and timeliness", coordinate with relevant departments and deal with all kinds of objections in a timely manner.
