Product Details
Round Coil Single Wall Steel Tube , Welded Steel Tube For
Refrigerator Application
Description:
Round Coil Single Wall Steel Tube, is manufactured through a
coiling and welding process. It is specifically designed for use in
refrigerators, where it is used to transport refrigerant and other
fluids. The tube's round shape and single wall construction ensure
efficient fluid flow and excellent heat transfer properties, making
it an ideal choice for this application.
- With smooth surface, the average roughness Ra is 0.6µm≤Ra≤1.9µm
- Inner cleanliness is 0.1948/m2 Max.
- Various ways of bending and cutting fabrication is possible
- Zinc, copper plating is available following customer’s request. The
hot galvanizing thickness can be above 8 µm
