API Std 650 vertical welded storage tanks seismic use group iii

Structural shapes of 9% and 5% nickel steel may be furnished to the chemical and physical requirements of ASTM A353, A553, or A645. Physical tests shall be in accordance with the requirements of ASTM A6.
API Std 650 vertical welded storage tanks used Piping, Tubing, and Forgings
Material used for piping, tubing, and forgings shall be compatible in welding strength, and thermal expansion coefficient with the tank shell material. In addition to the specific requirements of this appendix, all piping within the limitations of 1.3.2 shall fulfill the minimum requirements of ASME B31.3.

API 650 Application As described by the American Petroleum Institute, the fabrication and installation of our surface welded API Std 650 vertical welded storage tanks steel storage tanks is normally used in industrial applications. In general, our standards for industrial on-site installation of storage tanks are established according to API 650, API 620 and API 12D.

The cost of mechanical cleaning for vertical storage tank, API Std 650 vertical welded storage tanks is low, almost all oil can be recovered, and the quality of recovered oil is high. The cost of manual cleaning for vertical storage tank, API Std 650 vertical welded storage tanks is high, the oil can not be recovered completely, and the quality of recovered oil is low. The mechanical cleaning of API Std 650 vertical welded storage tanks adopts fully enclosed operation, and separates oil, water and oil sand. There is no direct discharge of oily sewage and waste gas, which will not pollute the environment.
