A537 Cl 2 plates API 650 ambient temperature tanks
Foundations and subgrade shall safely carry the weight of the tank API 650 ambient temperature 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.
While GB50341 generally takes the weld coefficient as 0.9;When the minimum yield strength of API 650 ambient temperature tanks steel plate is greater than 390 MPa, take 0.85. The thickness of API 650 tanks is generally smaller than that of GB50341, and this difference is particularly evident in the design of large tanks, where the overall weight of the tanks varies greatly.
In the year of 2015, customer from Peru oil refinery contact with us from Internet. After one month’s negotiation and quotation, they chose us as there supplier of raw steel plate API 650 ambient temperature tanks grade ASTM A36. We get an trail order of 300 tons in April. When the first ship arrived, they inspect the steel plate and very happy with the quality we supply. Then they put another 1700 tons order, we sent to them within 90 days. Our company management group visit the customer in the beginning of 2016 and the visit is very successful.
}Deformation of the welding seam of the API 650 ambient temperature tanks is a common quality problem during the actual use of the API 650 ambient temperature tanks, which easily causes the tank body to leak and affects the safety of the oil storage tank. The welding seam deformation of the API 650 ambient temperature tanks is mainly caused by the lack of reserved welding seam gap and irregular operation. The oil storage tank has not reserved the corresponding weld gap, resulting in deeper root removal during the front welding activity. The heat output of the weld will increase under the influence of a long time, and the deformation of the weld will gradually become serious.
It is very important for a company to have a sound after-sales service system, which better guarantees the interests of customers and increases the reliability of the company's products in the hearts of customers. Our company has a dedicated after-sales service team and good after-sales service reputation, and has been recognized by customers over the past decades. Whenever there is problem about our API 650 ambient temperature tanks steel materials during application on the user site, our after-sales service persons will assist to find solutions at the first time.
