API Std 650 self-anchored flat-bottom steel tanks allowable stresses

Floating roofs shall comply with API standard 650, Appendix C (Attachment 01) or with the API Std 650 self-anchored flat-bottom steel tanks requirements as layed (laid )down in the national Chinese specifications SH3046-92 and GBJ128-90.

The heat transfer oil fin tube heating device for large API Std 650 self-anchored flat-bottom steel 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

Pressure Setting of Safety DevicesExcept as provided in API 620 tank 9.5 for certain liquid relief valves, the pressure setting of a pressure-relieving device shall in no case exceed the maximum pressure that can exist at the level where the device is located when the pressure at the top of the tank equals the nominal pressure rating for the tank (see API 620 tank 5.3.1) and the liquid contained in the tank API Std 650 self-anchored flat-bottom steel tanks is at the maximum design level.Vacuum-relieving devices shall be set to open at such a pressure or partial vacuum that the partial vacuum in the tank cannot exceed that for which the tank is designed when the inflow of air (or other gas or vapor) through the device is at its maximum specified rate.
