Mechanical loads on API Std 650 ground supported tanks

The thickness of the API Std 650 ground supported tanks annular bottom plates shall be in accordance with Table Q-4 (for steel or aluminum, as applicable). The thicknesses shown are minimums. The ring of annual plates shall have a circular outside circumference, but it may have a regular polygonal shape inside the tank shell with the number of sides equal to the number of annular plates. These pieces shall be butt-welded in accordance with Q.7.1.1, Item b. The plates of the first shell course shall be attached to the annular bottom plates by a weld as required by API 620 oil tank 5.9.5 except when a full-penetration weld is used or required (see Q.7.1.1). Butt-welds in annular plates shall be not closer than 12 in. from any vertical weld.

Welding certification is regulated by Section 10 of the American Society of Mechanical Engineers (ASME). For both API Std 650 ground supported tanks storage tank API 650, non-destructive inspection is required, but third-party inspection is not required.

In January 2019, one of our Vietnam customer purchased 395.62 tons Q345B steel plate API Std 650 ground supported tanks for their construction project, we prepared all the goods ready within 5 days, and supplied the goods with painting sand blasting to SA2.5 API Std 650 ground supported tanks and priming gray oxide primer, and arrange shipment in time. Meet the customer urgent delivery request.

The preparatory work before the construction of the API Std 650 ground supported tanks is an important part of the oil tank project. Material purchase preparation before the construction of the API Std 650 ground supported tanks:
Before API Std 650 ground supported tanks construction, all materials shall be purchased and prepared, and the specifications and quality of materials shall be inspected to see if they meet the construction operation requirements. Fire and rain proof measures should be taken when storing materials. Paint should be stored in a ventilated and dry place.

If customers have any difficult problems during use of the steel materials, they can contact the company's after-sales service department to feedback the existing problems. The after-sales department will reply as soon as possible to ensure that each customer has a good after-sales experience. Under special circumstances, the after-sales service department will start the problem-solving process, and the engineers in charge of the area will quickly follow up to solve the problem.
