A573 grade 400 plates API 650 storage tank

Large net shell API 650 tanks or net shell of tank API 650 storage tank 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 storage tank large-scale tank top, its great spanning capacity and uniform stress, good rigidity, less material, convenient assembly, safe and reliable.

After using for a certain period of time, it is necessary to check the corrosion protection of the metal oil tank and paint the outer wall of the API 650 storage tank with anti-corrosion paint. The inlet and outlet valves of API 650 storage tank shall be inspected and maintained regularly to ensure they are in good condition. Oil tank will produce a lot of dirt when it is stored for a long time. Usually, the cleaning cycle of metal oil tank is about three to five years.

Welding of Large Steel Storage Tank Primary Components
a)Longitudinal and circumferential shell joints and joints that connect the API 650 storage tank annular bottom plates together.
b)Joints that connect sections of compression rings and sections of shell stiffeners together. Backup bars may be used for these joints with complete penetration and complete fusion detail.
c)Joints around the periphery of a shell insert plate.
d)Joints that connect the shell to the bottom, unless a method of leak checking is used (see Q.8.2.1).
