ASTM A516 plates API standard 650 aboveground oil storage tanks
API 650 tank has the advantages of less load on the floating plate, simple and light structure, and can save the central drainage pipe and rotating floating ladder on the API standard 650 aboveground oil storage tanks floating plate. The materials for easy construction and maintenance and sealing parts can avoid aging due to sunlight.
Ultrasonic testing can find the internal defects of API standard 650 aboveground oil storage tanks welding joint, this detection method is very accurate for the internal layer defects of oil tank, but ultrasonic detection is not suitable for the detection of thin-walled storage tank materials. Dye penetrant testing is only suitable for detecting the defects of the surface opening of API standard 650 aboveground oil storage tanks and so on metal oil tanks. The feature of this method is convenient and fast.
Stamping of API 620 Storage Tank PlatesBefore plates required to be stamped by the steel mill are used, the inspector shall see that they bear the stamp. In laying out and cutting the API standard 650 aboveground oil storage tanks plates, at least one set of the original material identification markings should, if possible, be left where it will be plainly visible when the tank is completed. Should the identifying marks be obliterateSpot radiographic or ultrasonic examination shall be not less than 6 in. extending along the weld. Spot radiography shall comply with the standards given in 7.15.1.3. Where spot radiographic or ultrasonic examination is applied at joint intersections, the surface shall be prepared and examined for a distance of 3 in. on each side of the intersection, making the minimum length of examination 6 in. on the horizontal weld and 3 in. on the vertical weld.
When talking about our team, it is hard not to mention our QC department (Quality Control). We have built strict qualitycontrol system to guarantee the steel quality. During the steel materials production, we have strict monitoring measures and indicators, and ensure no chemical composition, mechnical properties and so on technical problems for the steel materials API standard 650 aboveground oil storage tanks. After production, our QC department will conduct another inspection regarding to the steel quantity, dimension, mark and so on points before delivery.
Steel transportation because of the special material of API standard 650 aboveground oil storage tanks steel, is a metal with "iron" as the main basic element, small volume and large weight, and easy to oxidize and rust when contacting with air and rain water, so there are many precautions in the transportation of steel. There are 11 proverbs for steel transportation: "evenly placed, moisture-proof and rust proof". Our company chooses the logistics aspect to be very rigorous, takes the customer's request as the standard, guarantees the steel product quality.
