Heat Transfer Through SS Corrugated Tubing

I am looking to utilize flexible stainless steel corrugated tubing similar to this:

as a heat exchanger immersed in a tank but have been having a tough time locating technical data on it other than the "surface area" and of course the conductivity coefficient of steel. Do any of you know any way I could find out anything about the heat exchange this type of piping? I contacted the manufacturer in the above link but have yet to receive a response. Does there exist some type of calculation or data sheet I could use?

Thank you for your help
