CSA G40.21 grade 50WT plates API 650 ambient temperature tanks

Ultrasonic testing can find the internal defects of API 650 ambient temperature tanks welding joint, this detection method is very accurate for the internal layer defects of oil tank, but ultrasonic detection is not suitable for the detection of thin-walled storage tank materials. Dye penetrant testing is only suitable for detecting the defects of the surface opening of API 650 ambient temperature tanks and so on metal oil tanks. The feature of this method is convenient and fast.

API 650 petroleum storage tanks use lightning protection, anti-static, and fire protection measures. The internal corrosion protection should be determined according to the API 650 ambient temperature tanks storage medium, and the outer wall corrosion protection should be determined according to the soil quality of the buried tank.
