API standard 650 ground-supported liquid storage tanks fabrication

Similarities between API 650 and API 620 tanks Both tanks are used for storage purposes. Both API 620 and API 650 containers API standard 650 ground-supported liquid storage tanks can be made of carbon steel, austenitic stainless steel and nickel alloy (only for low temperature).

Uplift on Foundation
For 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.

The seal of floating roof API standard 650 ground-supported liquid storage tanks is a device used to reduce the evaporation loss of the storage liquid in the annular space between the tank wall and the outer ring plate of the floating roof. The common sealing forms include mechanical seal, elastic filling seal, lip seal and secondary seal. No matter what kind of seal, the seal must be combined with the floating roof effectively to reduce the evaporation loss of the liquid in the floating roof.

Iron and steel goods, including pig iron, ingots, all kinds of steel and so on. Therefore, logistics companies are required to load evenly and evenly in the process of transportation, prevent moisture and prevent corrosion. It is necessary to prevent the API standard 650 ground-supported liquid storage tanks steel sheet from being mixed with water when transporting the steel; it is necessary to prevent the API standard 650 ground-supported liquid storage tanks steel from being mixed with water when transporting the steel; it is necessary to prevent the steel from being mixed with water when transporting the steel; it is necessary to prevent the steel from being mixed with water when transporting the steel; it is necessary to prevent the steel from being mixed with water when loading the API standard 650 ground-supported liquid storage tanks steel sheet on the truck Good luck.
