Cold Drawn Steel Tube Corrugated Tube
Corrugated Tube
 |
FeatureCorrugated Tube is a steel pipe that can generate turbulent flow in the fluid that passes jurisdiction by forming a prescribed projection internally in the tube.It is sometimes used as energy-absorption parts for automobile. |

Standard Size
Standard size is designed to minimize pressure loss and to improve heat transfer performance.
In general, the ditch depth is related with thickness and diameter of material tube though the heat transfer performance is related with inside projection of the tube.
In each case, we may have a meeting to inspect customer's requirement.
