API 650 anchored tanks dimensional tolerances

Ultrasonic Examination of Butt-welds in Plates
Butt-welds in all tank wall courses subjected to a maximum actual operating membrane tensile stress, perpendicular to the welded joint, greater than 0.1 times the specified minimum tensile strength of the API 650 anchored tanks plate material shall be completely examined.
Butt-welds in API 620 oil tank wall courses subjected to maximum actual operating membrane tensile stress, perpendicular to the welded joint, less than or equal to 0.1 times the specified minimum tensile strength of plate material shall be spot examined in accordance with Figure Q-2.

The liquid level of API 650 oil storage tank is covered by floating roof. The storage liquid of API 650 oil storage API 650 anchored tanks tank is isolated from the air, reducing air pollution, fire and explosion hazards, and easy to ensure the quality of liquid storage. It is especially suitable for the API 650 anchored tanks storage of high-grade gasoline, jet fuel and toxic and easily polluted liquid chemicals.

A Uganda client purchased 2100 tons SG255 gas cylinder steel coils in 2018. It is the first company in Uganda to provide re-furbishing, re-certification and manufacturing of new lpg cylinders. They have regular demands for sg255 coils API 650 anchored tanks every 3 months. Limited by inland location, we can only ship container to mombasa, and then transfer to kampala. OurJISG3116 SG255 steel product is grade for gas cylinder steel with the tensile strength of 400MPa and the yield strength of 255MPa.

Weld inspection of API 650 anchored tanks, vertical oil tank wall plate: In the welding inspection process of oil tank wall plate, attention should be paid to the defects of thick wall plate, such as incomplete penetration, incomplete root fusion and cracks. If there is a root incomplete penetration defect, it is necessary to open the weld joint with carbon arc air gouging and grinding machine grinding, or even weld through, and then weld again after the defect is removed.

When providing technical services on site, the after-sales personnel shall strictly abide by the safety rules and regulations of the construction site, consciously take safety protection measures (such as wearing safety helmet when entering the construction site), accept the supervision and management of the site; without permission on the construction site, they shall not dismantle, smear or damage any goods; the commissioning of contract goods shall be carried out under the supervision of the site supervisor If necessary, it shall be approved by the site supervisor or the person in charge of the project department.
