The vent pipe mouth should be 4m or more above the ground. The nominal diameter of the API standard 650 petroleum storage tanks API 650 petroleum storage tank vent pipe should be no less than 50mm and a flame arrestor should be installed.
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 standard 650 petroleum storage 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.
The mechanical seal of floating roof API standard 650 petroleum storage tanks relies on mechanical force to press the sealing steel plate tightly against the tank wall, so that it can slide on the tank wall and avoid gap as far as possible. However, mechanical seal has high requirements for the geometry of storage tank and poor adaptability, so mechanical seal is rarely used in newly built floating roof API standard 650 petroleum storage tanks.
