API Std 650 mechanically-anchored flat-bottom tanks maintenance
API 650 internal floating roof oil tank executive standard: domestic design standard: GB50341-2003 "Vertical cylindrical steel welded oil tank design code"; domestic construction standard: GB50128-2005 "vertical cylindrical steel welded oil tank" Construction and Acceptance Specification; API Std 650 mechanically-anchored flat-bottom tanks Foreign design standard: API650-2007 "Standard for Welded Steel Petroleum storage tanks."
When the day light gradually decreases, the temperature of oil in the API Std 650 mechanically-anchored flat-bottom tanks will also decrease, the evaporation speed will gradually slow down, and the pressure in the API Std 650 mechanically-anchored flat-bottom tanks will also decrease. When the pressure in the API Std 650 mechanically-anchored flat-bottom tanks is lower than the negative pressure rating of the breathing valve, the outside air is sucked into the API Std 650 mechanically-anchored flat-bottom tanks through the open vacuum valve, which is the "suction" process of the oil tank.
API Std 650 mechanically-anchored flat-bottom tanks basic components are those that contain the vaporized liquefied gas from the stored refrigerated liquid but primarily operate at atmospheric temperatures because of insulation system design and natural ambient heating. These components shall comply with the basic rules of this standard. Examples of such components are the outer wall and roofs of double-wall tanks and roof components above an internally insulated suspended deck. The API 620 tank materials requirements are based on the storage of refrigerated products at the design metal temperature.
When talking about our team, it is hard not to mention our QC department (Quality Control). We have built strict qualitycontrol system to guarantee the steel quality. During the steel materials production, we have strict monitoring measures and indicators, and ensure no chemical composition, mechnical properties and so on technical problems for the steel materials API Std 650 mechanically-anchored flat-bottom tanks. After production, our QC department will conduct another inspection regarding to the steel quantity, dimension, mark and so on points before delivery.
