API Std 650 unanchored flat-bottom tank roof venting

API 650 is an American standard for welding flat bottom vertical storage tanks. This API Std 650 unanchored flat-bottom tank standard specifies requirements for the design, manufacturing, welding, inspection and installation of storage tanks. API 650 is widely used in storage tanks designed to withstand low internal pressures and used to store typical products such as API Std 650 unanchored flat-bottom tank crude oil, gasoline, chemicals and water. BBN has extensive experience in API 650 tanks, from +/- 500 cubic meters of tanks produced in the factory to +/- 15000 cubic meters of tanks produced on site.

A cylindrical nozzle with a 12-in. inside diameter is located in solid plate in the sidewall of a cylindrical storage tank 60 ft in diameter so that its axis lies in a horizontal plane and forms an angle of 55° with a perpendicular to the sidewall at the point of intersection, as shown in Figure F-7. The thickness of the API Std 650 unanchored flat-bottom tank sidewall plate, tw, in this area is 5/8 in., and no corrosion allowance is required. The total internal pressure, Pl + Pg, at the center of the opening is 26.1 lbf/in.2 gauge.

In order to prevent the deformation of the bottom of metal vertical storage tank, API Std 650 unanchored flat-bottom tank during welding, the number of welders should be reasonably distributed. When welding metal vertical API Std 650 unanchored flat-bottom tank, personnel and welding position shall be reasonably allocated according to the actual situation of welding personnel, and random welding is not allowed.
