Exploring a new type of heat exchange tube
Thread Content
This is a new type of non-metallic heat exchange tube material; the wall thickness can be customized to be over 1 mm. Its thermal conductivity is above 11 W/m.K, its density is 1.8 g/m3, and its tensile strength is above 20 MPa. It can be used at temperatures below 180 degrees Celsius, and it is resistant to corrosion by various acids, bases, salts, and organic solvents. Everyone, take a look at where it can be used?
Does anyone know anything about low-temperature economizers? Can we use this kind of tube?

This application is quite appropriate; the operating conditions of the economizer are very suitable for it
The unit of thermal conductivity is: W/m2.K. Convert it
The unit of the heat transfer coefficient is W/m2.K; here it refers to the thermal conductivity of the material, which is expressed in W/(m·K).
Compared to carbon steel pipes, this type of composite pipe is a corrosion-resistant material. In terms of cost, it is definitely higher than carbon steel for the same heat exchange area, and roughly on par with 316L.
What’s the unit price? In any case, it’s ultimately a matter of cost
The unit price is higher than that of carbon steel, roughly similar to 316L.
