A633 Gr C plates API standard 650 low-alloy steel tanks

API 650 is widely used for tanks that are designed to internal pressures of 2.5 PSI or less and store products such as crude oil, gasoline, chemicals and API standard 650 low-alloy steel tanks produced water. Advance Tank has extensive experience with API 650 tanks ranging in diameter from 8' - 300' for refineries, terminals, pipeline facilities and other clients.

When the API standard 650 low-alloy steel 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 standard 650 low-alloy steel 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.

API standard 650 low-alloy steel tanks any joints between the adjacent sections of stiffening rings, as shown in Figure R-1, shall be made so that the required moment of inertia of the combined ring-shell section is provided. Weld joints between adjacent sections shall be made with full-thickness and full-penetration butt-welds. Stiffening-ring butt-welds may employ metal backing strips. Backing strips and the associated welding shall be made in a manner that provides a smooth contour in the rat hole and all other weld joints ends. All weld passes shall be started at the rat hole.

Our team is a dynamic, but also mature and steady team. The talents are made of different ages. There are experienced ones, and also creative ones, that also makes our company culture diversified. We have complete department structure, to make the whole work procedure run smoothly. For every step, we have special person to be in charge and responsible for our customer and update information to the customer in time. So you just need not worry too much to purchase steel materials from our company.

The company's logistics adopts the method of cooperation with logistics companies. As a third-party logistics company is engaged in the operation of multiple logistics projects, it can integrate various logistics resources, making the logistics operation cost relatively low and the logistics operations more efficient. Thus we can provide more professional logistics services, while also focusing on our core business of steel materials.
