CSA G40.21 Gr 260WT plates API Std 650 carbon and low-alloy steel tanks
Floating roof is the key component of floating roof API 650 storage tank, which can be divided into external floating roof and internal API Std 650 carbon and low-alloy steel tanks floating roof. The internal floating roof has a fixed top cover above the floating roof, which can prevent the floating roof from being exposed to wind and rain, and ensure the quality of oil stored under API 650 storage tank.
Corrosion of the API Std 650 carbon and low-alloy steel tanks body caused by external conditions such as high temperature, rain, humidity, or inadequate anti-corrosion measures of the oil storage tank itself, the water-bearing deposits in the oil storage tank caused corrosion and perforation of the inner surface of the oil storage tank bottom plate. Defects fatigue cracks caused by stress, with the accumulation of time, the compressive strength of the API Std 650 carbon and low-alloy steel tanks body decreases and corrosion cracks occur.
