Butt-welds in annular plates shall be not closer than 12 in. from any vertical weld.
API 650 Tanks in which liquid fluids are stored and designed to withstand atmospheric pressure operation, less than 18 kPa, or internal pressures not exceeding the weight of the API Std 650 aboveground oil storage tanks roof, with temperatures no higher than 93, 3 C are included in the scope of this design code.
our company offered 2950 ton A36 steel API Std 650 aboveground oil storage tanks plate to Philippines customer, which was used to build water supply project. It is the government project. The procurement with their project engineer come to China to discuss this project in middle of 2016. After checking the mill, they signed the contract with us. we supply the ASTM A36 Original Mill Test Certificate Stamped.
}In the event of continuous heavy rainfall, the inspection of the API Std 650 aboveground oil storage tanks farm should be strengthened to monitor and pay close attention to the soil moisture content of the tank farm in order to quickly take emergency measures. Check whether the seals of the oil unloading port and the oil measuring port are in good condition in time to prevent rainwater from leaking into the API Std 650 aboveground oil storage tanks from the oil unloading port and the oil measuring port, which will affect the oil quality.
We should focus on the main problems to be solved and pay attention to efficiency. After receiving the user's quality objection report data, the possible causes, responsible units, compensation amount, etc. of the problem shall be judged based on experience.
