API Std 650 ground supported liquid storage tanks double-welded lap joint

API 650 storage tank stipulates that if the thickness of the lower wall panel obtained by calculating the anti-overturning moment is greater than the thickness of the API Std 650 ground supported liquid storage tanks hydrostatic pressure test (both do not include the corrosion allowance).

Atmospheric API Std 650 ground supported liquid storage tanks refer to storage tanks whose gas or vapor pressure is greater than -0.02MPa but less than 0.1MPa. Metal atmospheric storage tanks made of steel welded on the ground are often used to store petroleum, chemical and other similar liquids. Atmospheric API Std 650 ground supported liquid storage tanks usually have a connecting pipe directly connected to the atmosphere, so that the operating pressure in the storage tank does not exceed the design pressure at all times.

The horizontal projection of the roof plate within the compression-ring region is 4.9 x 0.866 = 4.25 in., which fulfills the requirement of API 620 tank standard 5.12.5.1. The required area and horizontal projection can be provided by any of the standard angles listed in Table F-3.
Any of these angles may be used in accordance with the details of Figure 5-6, detail a or b, but if details c, h, or i in Figure 5-6 were intended, the net area of the angle must be calculated by deducting the area expected to be lost by corrosion from that part of the angle surface that is exposed to the interior of the tank.

Our company attaches great importance to technical support and after-sales service, and has established a customer service center to provide unified technical support and service for API Std 650 ground supported liquid storage tanks various engineering projects.
