Alclad 3003 aluminum tube API standard 650 liquid storage tanks

Allowable Design Stresses
The maximum allowable design stresses for the API standard 650 liquid storage tanks materials outlined in Q.2.1 shall be in accordance with Table Q-3.The values for the allowable design tensile stress given in Table Q-3 for materials other than bolting steel are the lesser of (a) 331/3% of the specified minimum ultimate tensile strength for the material or (b) 662/3% of the specified minimum yield strength, but they are 75% of the specified minimum yield strength for the stainless steel, nickel alloy, and aluminum materials. Allowable test stresses are based on the limitation of API 620 oil tank storage standard Q.8.1.3.Welded steel API standard 650 liquid storage tanks storage tanks that are designed, manufactured and installed on the ground are classified according to the API standard system. The three API standards API standard 650 liquid storage tanks all adopt on-site production and installation of storage tanks.The Indonesia INKA is the only train carriage maker for railway industry in Indonesia. We cooperated with them since 2012 and supply them SPA-H steel. The SPA-H steel is used by them to fabricate train carriage. We have huge stocks for SPA-H steel and can arrange delivery for them in short time after receiving order. Meanwhile, our product API standard 650 liquid storage tanks quality has passed their test for so many times use. Therefore, they trust us and give us repeat orders regularly. And we also do our best to support them and have never let them down though past cooperations.When the day light gradually decreases, the temperature of oil in the API standard 650 liquid storage tanks will also decrease, the evaporation speed will gradually slow down, and the pressure in the API standard 650 liquid storage tanks will also decrease. When the pressure in the API standard 650 liquid storage tanks is lower than the negative pressure rating of the breathing valve, the outside air is sucked into the API standard 650 liquid storage tanks through the open vacuum valve, which is the "suction" process of the oil tank.Over the years, the company has strived for perfection, being well-received. By virtue of stable product performance, high-quality engineering effects and perfect service system, we have won the trust of many customers, and our engineering cases and after-sales service systems are spread all over the world. We regularly conduct quality tracking and return visits by phone and email, listen to customers' opinions, and continuously improve service quality.
