API 650 aboveground oil storage tanks stainless steel armored hose
In this project, an area of steel storage oil tank wall is constructed of ASTM A285, Grade C, steel plate that is 5/8-in. thick and has spot-radiographed, double-welded butt joints. The wall is subject to tension in a meridional direction and to compression in a latitudinal direction. The values of R1 and R2 at the point under consideration are 75 in. and 300 in. respectively. A corrosion allowance of 1/16 in. is required. The computed (meridional) tensile stress, stc, in the net thickness after deduction of the corrosion allowance is 6000 lbf/in.2.
API 650 external floating roof storage tanks are generally called external floating roof API 650 aboveground oil storage tanks tanks, which means that the storage tanks are externally open tanks without a dome design, and are equipped with vertical floating roofs. API 650 external floating roof storage tanks are usually used for large More than 20,000 cubic meters of open steel API 650 aboveground oil storage tanks storage tanks for storing volatile petroleum products such as crude oil, gasoline, kerosene, etc.
Square hollow section S355J2H to Turkey. In January of 2015, our customer from Turkey chose us as their supplier of seamless RHS EN10219 S355J2H with a trail order of 120 tons. They required DNV test for the MTC and each tube. DNV inspector tested all the tubes and MTC. When our customer received the reports, they gave us a second order of 852.5 tons. Since then we maintain a long time cooperation relationship.
}When the day light gradually decreases, the temperature of oil in the API 650 aboveground oil storage tanks will also decrease, the evaporation speed will gradually slow down, and the pressure in the API 650 aboveground oil storage tanks will also decrease. When the pressure in the API 650 aboveground oil storage tanks is lower than the negative pressure rating of the breathing valve, the outside air is sucked into the API 650 aboveground oil storage tanks through the open vacuum valve, which is the "suction" process of the oil tank.
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.
