How to limit evaporation of liquid contents from API 650 flat-bottom oil storage tanks

Similarities between API 650 and API 620 tanks Both tanks are used for storage purposes. Both API 620 and API 650 containers API 650 flat-bottom oil storage tanks can be made of carbon steel, austenitic stainless steel and nickel alloy (only for low temperature).

Generally speaking, the duration of the "exhalation" of the API 650 flat-bottom oil storage tanks is longer than that of the "inhalation" of the API 650 flat-bottom oil storage tanks every day. There are many factors affecting the "small breathing" loss, mainly including the following points: the change of temperature difference between day and night, sunshine time of the API 650 flat-bottom oil storage tanks location, open area of the API 650 flat-bottom oil storage tanks, atmospheric pressure, filling degree of API 650 flat-bottom oil storage tanks, etc. When the API 650 flat-bottom oil storage tanks is full of gas, the space volume is small, and the "small breathing" loss is less; if the space volume is large, the loss is also large.

The refrigerated tank primary components shall also include those parts of a single-wall or an inner tank that are not in contact with the refrigerated liquid but are subject to the refrigerated temperature. Such API 650 flat-bottom oil storage tanks components include roof plates, roof manways and nozzles with their reinforcements, roof-supporting structural members, and shell stiffeners when the combined tensile and primary bending stresses in these components under design conditions are greater than 6000 lbf/in.2.

Our quality control department will do inspection for details of the steel materials API 650 flat-bottom oil storage tanks before delivery. We would invite the customer side to attend the inspection together. If they can not come, we will also take rich pictures for them to check. Meanwhile, we will publish inspection report and send them the PDF version. Besides, we accept any third party inspection such as SGS, BV, etc. And our quality control department will support the third party to inspect the steel materials smoothly and try our best to deliver the qualified steel materials to customers earlier.
