Fixed roof API 650 mixed material tanks

Ultrasonic testing can find the internal defects of API 650 mixed material 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 mixed material tanks and so on metal oil tanks. The feature of this method is convenient and fast.API 620 Crude Oil Tank Non-pressure Parts
Welds for pads, lifting lugs, and other nonpressure parts, as well as temporary lugs for alignment and scaffolding attached to primary components, shall be made in full compliance with a welding procedure qualified in accordance with Q.6.1. Lugs attached for erection purposes shall be removed, and any significant projections of API 650 mixed material tanks weld metal shall be ground to a smooth contour. Plate that is gouged or torn in removing the lugs shall be repaired using a qualified procedure and then ground to a smooth contour. Where such repairs are made in primary components, the area shall be inspected by the liquid-penetrant method. A visual inspection is adequate for repairs in secondary components.Welding certification is regulated by Section 10 of the American Society of Mechanical Engineers (ASME). For both API 650 mixed material tanks storage tank API 650, non-destructive inspection is required, but third-party inspection is not required.The cultural construction must let the enterprise staff participate in the enterprise culture, in order to better carry on the effective dissemination enterprise idea, the sharing value system, such as the internal communication, the newspaper, the forum, the propaganda, the news announcement and so on.
