API standard 650 special tank roof plate

High temperature heat transfer oil fin tube heating device for large API standard 650 special tank 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.

Welding of API 620 Steel Storage Tank Primary Components
The following primary components shall be joined with double butt-welds that have complete penetration and complete fusion except as noted:
Longitudinal and circumferential shell joints and joints that connect the annular bottom plates together. When approved by API standard 650 special tank Purchaser, these may be welded from a single side provided temporary non-fusible backing is used with complete penetration and complete fusion. Both sides of the joint shall be 100% visually examined as specified in 7.15.5.

Oil, Gas, Chemical, Water, and Bio-Fuel storage. Maximum of the most common welded steel tanks used in industry are designed following API 650. Tanks typically found in Refinery API standard 650 special tank tank farms, Terminals, Pipelines, and other process facilities use these tanks.
