Performance:

High efficient heat transfer tubes is the pipe that strengthen the smooth inner and outer surfaces ,to improve the heat transfer.

We process the inner and outer surfaces of the heat transfer tubes into various shapes (spiral squamous teeth, bumps, grooves Etc.) via extrusion, rolling, rolling Etc. Through changing the flow field of the liquid on the wall of the pipe, forming a turbulent flow, improving the convection effect.At the same time,through the physical processing, extended the inner and outer surface, increase the inner and outer surfaces of the heat transfer area, improve the heat transfer efficient of steel pipe.

The inner of our tube has helical teeth,which can enhance convection of water, improve the heat transfer.

We can produce various efficient duplex stainless steel tubes.Outer diameter ,thickness can be produced according to customer requirements.
