A516 grade 70 plates API 650 unanchored flat-bottom tank

According to API standard 650, the stairs used for API 650 petroleum storage tanks or thermal insulation tanks should be double longitudinal beams supported by a minimum of ribs. If the gap between the API 650 unanchored flat-bottom tank tank shell and the stringer of the API 650 petroleum storage tank exceeds 200mm, handrails should be provided on both sides of the stairs. Unless otherwise specified, according to API 650 unanchored flat-bottom tank ASTM A123, the following accessories shall be hot-dip galvanized. The damaged zinc coating should be repaired with zinc alloy.

The factors that affect the "small breathing" loss of API 650 unanchored flat-bottom tank are: 1. Generally, the larger the storage tank is, the larger the total open area is, the larger the evaporation area is, and the greater the "small breathing" loss is; conversely, the smaller the storage tank is, the smaller the evaporation area is and the smaller the "small breathing" loss is. 2. It is related to the atmosphere. The lower the atmospheric pressure is, the greater the "small breathing" loss is; otherwise, the loss is reduced.

Cylindrical Oil Storage Tanks Discharge Pipes
When a discharge pipe is used on the outlet side of such relieving devices, its area shall be not less than the area of the valve outlet, or if a single pipe provides for discharge from several relief devices, its area shall be not less than the aggregate area of the valve outlets. The API 650 unanchored flat-bottom tank discharge pipe shall be fitted with an open drain to prevent water or other liquids from lodging in the discharge side of the valves.
Discharge pipes shall be supported so that no undue stress is placed on the valve body. Open discharges shall be placed and oriented so that the outflow is directed away from the tank and will not create a hazard over walkways, stairways, or operating platforms.
