The heat transfer oil fin tube heating device for large API620 steel storage tank construction 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

When as-rolled plate material complies with impact test requirements as specified here, the material need not be normalized. If, as with ASTM A516, the specification prohibits impact test without normalizing but otherwise permits as-rolled plates, the API 620 welded storage tanks material may be ordered in accordance with the above provision and identified as “MOD” for this API modification.

Under the same sealing effect, the internal floating roof tank of API 650 oil storage tank can further reduce the evaporation loss compared with the API620 steel storage tank construction external floating roof tank. This is due to the shielding of the fixed roof and the gas layer between the fixed roof and the internal floating plate, which has more significant heat insulation effect than the double disc floating roof of the API620 steel storage tank construction external floating roof tank. =====
API 650 tank has the advantages of less load on the floating plate, simple and light structure, and can save the central drainage pipe and rotating floating ladder on the API620 steel storage tank construction floating plate. The materials for easy construction and maintenance and sealing parts can avoid aging due to sunlight.

In December of 2015, our regular India customer sent us an inquiry for API620 steel storage tank construction pipe. The inquiry requires no negative tolerance in both pipes’ outer diameter and pipe wall. After two weeks’ discussion, he put the order of 275 tons to us. The pipes are finished within just one month. Our customer come to our factory to inspect the quality and tolerance, all the products are well meet his demand. The pipes are arriving to Nhava Sheva port, customer is very happy with our products and service during the process.
