Sliding friction resistance of API Std 650 unanchored tanks

The calculated thickness of the above-mentioned wall panels required by the hydrostatic pressure is also It API Std 650 unanchored tanks should be increased by the same ratio, unless special analysis is performed to determine the seismic overturning moment and the corresponding stress at the bottom of the wall of each layer of API 650 tank.

Comparison of the quality of mechanical cleaning and manual cleaning of vertical storage tanks, API Std 650 unanchored tanks. The mechanical cleaning of the API Std 650 unanchored tanks can make the inside of the tank be thoroughly cleaned in multiple directions, and the cleaning quality is high, and the cleaned oil does not contain lumpy impurities. While the walls and roof of the API Std 650 unanchored tanks cannot be cleaned in multiple directions during manual cleaning, and the cleaning quality is not easy to be guaranteed. The oily sewage collected after cleaning usually contains a lot of lumpy impurities, and these oil products are difficult to clean.

Production Weld Tests
Production weld test plates shall be welded for API Std 650 unanchored 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.
