ISO 630 grade E355 quality D plates API Std 650 carbon steel storage tanks
API 650 Application As described by the American Petroleum Institute, the fabrication and installation of our surface welded API Std 650 carbon steel 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 materials used in the construction of Appendix Q oil tanks may be subject to severe pitting, cracking, or rusting if they are exposed to contaminated test water for extended periods of time. The Purchaser shall specify a minimum quality of test water that conforms to Q.8.3.2 through Q.8.3.8. After the water test is completed, the tank API Std 650 carbon steel storage tanks shall be promptly drained, cleaned, and dried.
High temperature heat transfer oil fin tube heating device for large API Std 650 carbon steel storage 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.
