API Std 650 carbon and low-alloy steel tanks lateral loads on columns
Inspection of Butt-welds in PipingButt-welds in piping and in API Std 650 carbon and low-alloy steel tanks pipe fittings within the limitations of 1.3.2 (including the annular space of double- wall tanks) shall be inspected in conformance with API 620 oil tank standard Q.7.7.2 through Q.7.7.6. Longitudinal welded joints in piping that contains liquid shall be completely radiographed except for manufactured pipe welded without filler metal, 12 in. or less in diameter, which is tested hydrostatically or by eddy current to ASTM requirements.
This API 650 tank standard is designed to provide industry with tanks of adequate safety and reasonable economy for use in the API Std 650 carbon and low-alloy steel tanks storage of petroleum, petroleum products. and other liquid products.
How to effectively increase the service life of API Std 650 carbon and low-alloy steel tanks oil tanks? It is necessary to check and inspect the oil tank regularly in the process of use, and do a good job in the maintenance and cleaning of the oil tank. The oil tank should be inspected every 6 years. With the increase of service life, the inspection interval should be shortened. Daily maintenance and cleaning of the API Std 650 carbon and low-alloy steel tanks can prolong the service life of the oil tank. The maintenance of the API Std 650 carbon and low-alloy steel tanks mainly includes the anti-corrosion inspection of the oil tank, the maintenance of the accessories, and the cleaning of the sediment in the tank.
