A131 grade EH36 plates API standard 650 flat-bottom steel tanks

The water dissolved in the oil will be separated out from the oil stored in the API standard 650 flat-bottom steel tanks for a long time, and the acidic water layer will appear at the bottom of the API standard 650 flat-bottom steel tanks for a long time, which will accelerate the corrosion of the API standard 650 flat-bottom steel tanks and cause the wall thinning and even leakage. With the increase of service life, the API standard 650 flat-bottom steel tanks must be inspected and cleaned regularly to check the hidden danger.Production Weld Tests
Production weld test plates shall be welded for API standard 650 flat-bottom steel tanks primary-component butt-welded shell plates when welding procedure qualifications are required to be impact tested per Q.6.2 and Q.6.3. The number of production weld tests shall be based on the requirements of Q.6.6.3 and Q.6.6.4. The locations impact tested (i.e., HAZ and/or weld deposits) shall likewise be the same as required for weld procedure qualifications per Q.6.2 and Q.6.3. Weld testing shall be in accordance with Q.6.6.5. Test plates shall be made from plates produced only from the heats that are used to produce the shell plates for the large welded steel tank.The liquid level of API 650 oil storage tank is covered by floating roof. The storage liquid of API 650 oil storage API standard 650 flat-bottom steel tanks tank is isolated from the air, reducing air pollution, fire and explosion hazards, and easy to ensure the quality of liquid storage. It is especially suitable for the API standard 650 flat-bottom steel tanks storage of high-grade gasoline, jet fuel and toxic and easily polluted liquid chemicals.we develop very well through those years even the external environment is not conducive to the whole steel industry.
