API Std 650 uplifting tanks butt-welded bottom joints
The API Std 650 uplifting tanks outer tank, which is not in contact with the vaporized liquefied gas, may be of single-welded lap or single-welded butt construction when the thickness does not exceed 3/8 in.; at any thickness, the API 620 oil tank outer tank may be of double- welded butt construction without necessarily having full fusion and penetration. Single-welded joints shall be welded from the outside to prevent corrosion and the entrance of moisture.
The calculated thickness of the above-mentioned wall panels required by the hydrostatic pressure is also It API Std 650 uplifting 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.
With the fast development in Myanmar, Myanmar navy build frigate every year. We Cooperate with Myanmar Navy from 2015. They purchased 412 ton LR AH36 steel plate from us as trial order in 2015. After receiving the API Std 650 uplifting tanks goods, they speak highly of the quality and our service. After that they purchase the shipbuilding steel plate from us regularly. In May,2018, the Myanmar navy’s local representative visit our office and production line, and sign another contract 2025 ton steel order in our office.
}Due to irregular operation of API Std 650 uplifting tanks welding, there are many weld deformations during the construction process. Before specific operations, most construction units have formulated relatively complete construction plans and set up special welding process instructions, but the operators have not fully performed welding in accordance with various process guidance requirements and construction specifications, resulting in some quality problems of oil storage tanks. How can we reduce or even avoid this kind of situation?
We should help solve the customer's problems in time, not just verbally, without solving the problems or shirking the responsibility. Improving after-sales efficiency can make customers feel respect. We should take their problems seriously and show sincerity. It can also give customers a good impression and reduce the negative impact.
