API Std 650 self-anchored flat-bottom steel tanks testing of the shell

Foundations and subgrade shall safely carry the weight of the tank API Std 650 self-anchored flat-bottom steel tanks and its contents when the tank is filled with water to the highest level required for a hydrostatic test or other water-loading operations, even though the tank itself may be designed for some lesser density of liquid. However, in cases where the character of the soil justifies it and a competent soil expert advises it, allowance may be made for the relatively short duration and intermittent nature of the water loadings if suitable account is taken of all such loadings that may be expected to occur during the life of the tank, including not only those loadings that are incidental to periodic repetitions of the hydrostatic test in accordance with 7.18 but also water-filling operations for gas-freeing purposes.

The calculated thickness of the above-mentioned wall panels required by the hydrostatic pressure is also It API Std 650 self-anchored flat-bottom steel tanks should be increased by the same ratio, unless special analysis is performed to determine the seismic overturning moment and the corresponding stress at the bottom of the wall of each layer of API 650 tank.

The Peru customer has cooperated with us since April 2015, and then they purchased 300 tons A36 mild steel plates as trial order. Since then, they book more than 1000 tons from us every time, and about two times every year. They asked SGS test every time. Through our cooperation those years, we have built very good relationship and they entrust us to buy other related API Std 650 self-anchored flat-bottom steel tanks products for them from China also. And they have introduced us good customers in Peru, among which there are also governmental projects. It is a win-win cooperation between us.

Generally, the building area temperature of the API Std 650 self-anchored flat-bottom steel tanks should be considered before the tank design and construction. The temperature in the API Std 650 self-anchored flat-bottom steel tanks building area is closely related to the evaporation loss, energy loss, storage tank materials and the selection of detection instruments, or has a direct impact on the storage cost of the storage liquid. For the same medium, the higher the air temperature and the longer the duration, the higher the material temperature in the API Std 650 self-anchored flat-bottom steel tanks, the higher the corresponding pressure and the more volatile loss.

The after-sale service of iron and steel products includes after-sale tracking service, technical guidance, transfer of relevant bills, handling of objections and many other contents. The handling of quality objections accounts for a large proportion. When dealing with these problems, we should distinguish the responsibilities, and compensate or return the inconvenience or loss caused to users due to steel.
