chinese boiler tube stainless steel heat exchanger shell and tube
Our heat exchanger tube in stainless steels are suitable for all types of heat exchangers for conveying all types of gases and liquid with extreme low and high temperature requirements, such as sea water coolers, condensers, evaporators, heaters and reheaters.
They are used for heating, re-heating or cooling of gases, air or fluids in an extensive range of industries like chemical processing, aerospace and nuclear power generation, hydro carbon processing and oil refining.
Our heat exchanger tubes are appreciated for the feature such as dimensional accuracy, corrosion resistance, easy installation and smooth finishing.
