ASTM A283 plates API Std 650 SUG III tanks

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.The welded API 650 tank in various sizes and capacities for internal pressures approximating atmospheric pressure (internal pressures not exceeding the weight of the roof plates), but a higher internal pressure API Std 650 SUG III tanks is permitted when additional requirements are met.In 2014, we offered 175 ton Cold rolled stainless steel plate to Thailand. The API Std 650 SUG III tanks products are from TISCO. Here is the MTC that we offered to customer. We have our own quality team. Our quality team will inspect every order before shipment for customer. Normally, we will test the chemical composition, thickness, width, and length. Here are some pictures for last inspection.The lip seal of floating roof storage tank, API Std 650 SUG III tanks relies on the sliding contact between elastic lip and tank wall. This kind of seal has strong applicability, but the requirements of manufacturing technology and material selection are high, and the determination of elastic seal also exists. The secondary seal of floating roof storage tank, API Std 650 SUG III tanks is to add a seal on the basis of primary seal. It is proved by experiments that the secondary seal can reduce the liquid consumption by more than 50%, and has a more significant effect in safety.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.
