API Std 650 ground supported liquid storage tanks magnetic particle examination

API Std 650 ground supported liquid storage tanks, Vertical oil storage tank is an important equipment for many enterprises to carry out production, which provides important support and help for the storage of many reagents. Vertical storage tank is generally used as atmospheric pressure vessel. Advantages: the filling rate of cylindrical structure is second to that of spherical tank, and the largest volume of the storage tank can be made into tens of thousands of cubic meters. The structure is simple and the construction requirements are relatively low.

Production Weld Tests
Production weld test plates shall be welded for API Std 650 ground supported liquid storage 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.

Floating roofs shall comply with API standard 650, Appendix C (Attachment 01) or with the API Std 650 ground supported liquid storage tanks requirements as layed (laid )down in the national Chinese specifications SH3046-92 and GBJ128-90.
