API Std 650 larger diameter tanks bottoms
API 650 storage tank is used for commonly used oil, gasoline, diesel, chemical and production water storage. API Std 650 larger diameter tanks Storage tanks built to these standards are spread across U.S. refineries, terminals, pipelines, and production facilities. The API 650 detailed standard specifies the design, processing, welding, inspection and installation procedures for storage tanks.
When the day light gradually decreases, the temperature of oil in the API Std 650 larger diameter tanks will also decrease, the evaporation speed will gradually slow down, and the pressure in the API Std 650 larger diameter tanks will also decrease. When the pressure in the API Std 650 larger diameter tanks is lower than the negative pressure rating of the breathing valve, the outside air is sucked into the API Std 650 larger diameter tanks through the open vacuum valve, which is the "suction" process of the oil tank.
For all API 620 crude oil tank other materials, the impact test temperature shall be at least 30°F colder than the design metal temperature. Alternately, materials impact tested at the design metal temperature or lower with Charpy impact test energy value of 25 ft-lb (average), 20 ft-lb (minimum) are acceptable for design metal temperatures above –40°F. API Std 650 larger diameter tanks materials with an energy value of 30 ft-lb (average), 25 ft-lb (minimum) are acceptable for design metal temperatures of –40°F or lower.
