200ft diameter API 650 open-top tanks

Before welding the API 650 open-top tanks, the professional skills of the welding personnel shall be fully assessed to ensure that the operators meet the corresponding welding qualifications. According to the technical standards, scientific and feasible process requirements are actually formulated. In the process of welding the edge plate of API 650 open-top tanks, electric welding is required on one side of the edge plate, so that the edge plate has a free shrinkage effect and greatly reduces the residual stress of the welding seam.

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 open-top 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.

Large net shell API 650 tanks or net shell of tank API 650 open-top tanks is a tank top for the surface grid structure and the physical structure form of truss structures, thin shell structure is reasonable, mainly for the top using triangle net shell, socket type net shell or meridian reticulated shell technology for the design of API 650 open-top tanks large-scale tank top, its great spanning capacity and uniform stress, good rigidity, less material, convenient assembly, safe and reliable.
