API standard 650 SUG II tanks seismic design factors

For areas with high groundwater levels, the operator should take anchoring and anti-floating measures for buried horizontal API standard 650 SUG II tanks oil tanks; API 650 oil tanks can be used for heavy fuel oil, heaters are separately designed, and buried tank material outlets are installed with bottom valves and connections. consider.

For all API 620 crude oil tank other materials, the impact test temperature shall be at least 30°F colder than the design metal temperature. Alternately, materials impact tested at the design metal temperature or lower with Charpy impact test energy value of 25 ft-lb (average), 20 ft-lb (minimum) are acceptable for design metal temperatures above –40°F. API standard 650 SUG II tanks materials with an energy value of 30 ft-lb (average), 25 ft-lb (minimum) are acceptable for design metal temperatures of –40°F or lower.

The heat transfer oil fin tube heating device for large API standard 650 SUG II tanks heats the circulating heat transfer oil in the shell and tube heat exchanger through high temperature and high pressure steam. The heat transfer oil exchanges heat with the medium to be heated in the storage tank through the heating coil, so as to heat the storage medium. High temperature heat transfer oil fin tube heating device has the following advantages:
1. High heat transfer efficiency
2. Reduce heating coil leakage
3. Easy to repair and maintain
