A516 Gr 450 plates API standard 650 low-alloy steel tanks

High temperature heat transfer oil fin tube heating device for large API standard 650 low-alloy steel tanks has the advantage of reducing the leakage of heating coils. The heating medium of the large storage tank heating device is high-temperature heat-conducting oil. The boiling point of the heat-conducting oil is high, usually higher than 200°C. At high temperatures, the pressure on the heat-conducting oil circulation pipeline is very small, which greatly reduces the occurrence of heating coil leakage accidents. At the same time, the temperature difference between the inside and outside of the tube is guaranteed.

In addition to the requirements of API Standard 620 tank Appendix Q.8.1, the nameplate shall be attached to the tank at an accessible location if it is outside of any insulation or protective covering of the tank. The nameplate for the inner tank shall be located on the outer tank wall but shall refer to the inner tank. The nameplate, if any, for the outer tank of a double-wall tank shall be located adjacent to the nameplate or the inner tank and shall refer to the outer tank.

The internal floating plate of internal floating roof tank of API 650 tank is different from that of open floating plate of API standard 650 low-alloy steel tanks External floating roof tank of API 650 tank, so it is impossible to have rain and snow load.
