A633 Gr C plates API 650 low-alloy steel tanks

API standard 650, Welded Tanks for Oil Storage, Thirteenth Edition, has been published to ensure the safety, sustainability, and environmental performance of API 650 low-alloy steel tanks oil storage tanks. The updated standard will help continue operational excellence and trust between operators and manufacturers.

Tank cracks are common API 650 low-alloy steel tanks defects, mainly including tank wall cracks, internal cracks, weld zone cracks. The reason for these defects may be that the defects not exceeding the standard existed in the early stage of API 650 low-alloy steel tanks construction, which become obvious after the later use. Or in the process of using the API 650 low-alloy steel tanks, the tank body material generated new defects due to corrosion, pressure, wear and other reasons, and tank cracks.

API 650 low-alloy steel tanks Pressure-relieving DevicesTanks shall be protected by automatic pressure-relieving devices that will prevent the pressure at the top of the tank from rising more than 10% above the maximum positive gauge pressure except as provided in API 620 standard 9.2.2.Where an additional hazard can be created by the exposure of the tank to accidental fire or another unexpected source of heat external to the tank, supplemental pressure-relieving devices shall be installed. These devices shall be capable of preventing the pressure from rising more than 20% above the maximum positive gauge pressure. A single pressure-relieving valve may be used if it satisfies the requirements of this paragraph and 9.2.1.
