API Std 650 aluminum storage tanks design thickness

The refrigerated tank primary components shall include, but will not be limited to, the following parts of a single-wall tank or of the inner tank API Std 650 aluminum storage tanks in a double-wall tank: shell plates; bottom plates; knuckle plates; compression rings; and shell manways and nozzles including reinforcement, shell anchors, piping, tubing, forgings, and bolting. Roof nozzles in contact with the refrigerated liquid shall be considered primary components.

API 650 is an American standard for welding flat bottom vertical storage tanks. This API Std 650 aluminum storage tanks standard specifies requirements for the design, manufacturing, welding, inspection and installation of storage tanks. API 650 is widely used in storage tanks designed to withstand low internal pressures and used to store typical products such as API Std 650 aluminum storage tanks crude oil, gasoline, chemicals and water. BBN has extensive experience in API 650 tanks, from +/- 500 cubic meters of tanks produced in the factory to +/- 15000 cubic meters of tanks produced on site.

When the API Std 650 aluminum storage tanks is welded, the weldment should be fixed rigidly. After welding, when the weldment is cooled to normal temperature, the rigid fixation can be removed, which can effectively prevent angular deformation and wave deformation. Although some measures have been taken, the welding deformation of API Std 650 aluminum storage tanks is still unavoidable, so it is necessary to take corrective measures to compensate the deformation. Mechanical correction is to make the parts easy to deform in the welding process by mechanical or other rigid materials to produce simple deformation, so as to restore the state before welding.
