API standard 650 anchored tanks overfill protection level

Our quality control department will do inspection for details of the steel materials API standard 650 anchored tanks before delivery. We would invite the customer side to attend the inspection together. If they can not come, we will also take rich pictures for them to check. Meanwhile, we will publish inspection report and send them the PDF version. Besides, we accept any third party inspection such as SGS, BV, etc. And our quality control department will support the third party to inspect the steel materials smoothly and try our best to deliver the qualified steel materials to customers earlier.Inspection of low-pressure storage tank Butt-weldsComplete penetration and complete fusion is required (to the degree mandated by the acceptance criteria for examination method utilized) for welds joining tank wall plates to API standard 650 anchored tanks tank wall plates. Examination for quality of welds shall be made using either the radiographic method specified in API 620 standard 7.15.1 and applied in 7.17, or alternatively, by agreement between the Purchaser and the Manufacturer, using the ultrasonic method specified in 7.15.3.1. In addition to the radiographic or ultrasonic examination, these welds shall also be visually examined as specified in 7.15.5. Furthermore, the Purchaser’s inspector may visually inspect all butt-welds for cracks, arc strikes, excessive undercuts, surface porosity, incomplete fusion, and other defects.Structural features of API 650 double-layer oil tank: steel glass fiber reinforced plastic double-layer structure, special processing method is adopted between the API standard 650 anchored tanks internal steel shell and glass fiber reinforced plastic layer, so that a gap of 01 mm is created between the internal and external layers Even if the API 650 oil storage tank leaks, it can ensure that the contained dangerous substances only flow in the gap, and will not immediately overflow the external environmentOn November 1st, our company organized some of company staff to visit Zhengzhou Children Welfare Institute, and gave children cookies and toys, as well as concerns to the Children With the development of the society, disabled children gets increasing concerns and help from all walks of life Fortunately, Chinese Government gives high concern to the handicapped children and has built Children Welfare Institutes all over the country to guarantee their lives,API standard 650 anchored tanks. Breathing valve: The function of the oil tank breathing valve is to adjust the oil and gas pressure in the tank. When the pressure in the tank is too high, part of the excess oil and gas will be discharged through the breathing valve to reduce the pressure in the tank; when the pressure in the tank is too low, through breathing The valve sucks in air from the outside of the tank to increase the pressure in the tank and keep it constant with the atmospheric pressure. The breathing valve is usually installed at the top of the oil tank.
