API Std 650 unanchored flat-bottom tank seal materials

API 650 petroleum storage tank has the advantage of long economic life: because there is no gas space on the liquid surface in the internal floating roof API Std 650 unanchored flat-bottom tank storage tank, the vibration generated during the transportation of liquid inside and outside the tank is reduced.

The preparatory work before the construction of the API Std 650 unanchored flat-bottom tank is an important part of the oil tank project. Material purchase preparation before the construction of the API Std 650 unanchored flat-bottom tank:
Before API Std 650 unanchored flat-bottom tank construction, all materials shall be purchased and prepared, and the specifications and quality of materials shall be inspected to see if they meet the construction operation requirements. Fire and rain proof measures should be taken when storing materials. Paint should be stored in a ventilated and dry place.

The tank 20-in. inside-diameter nozzle shown in Figure F-6 is located in solid plate in the sidewall of a cylindrical storage tank 148 ft in diameter in an area where the thickness of the wall plate, tw, is 11/2 in. A corrosion allowance of 0.10 in. is required on all surfaces of the tank exposed to the stored liquid. The total internal pressure, Pl + Pg, at the center of the opening is 24.9 lbf/in.2 gauge. The thickness of the API Std 650 unanchored flat-bottom tank wall plate, t, required by 5.10.3 for the latitudinal unit forces, T2, acting at this level is 1.44 in.
