KL type finned tube is also known as knurled finned tube. It is used to roll the pattern on the base tube before winding the fin, or to add a blade on the winding machine. Knurling is used on the base tube, and the blade behind is used for winding.
Applicable scope and features:
A. Maximum operating temperature ≤250°C
B. Maximum operating pressure ≤ 3.2mpa
C. Advantages: 1. High heat transfer performance, small contact resistance.
2. The fin has a large contact area with the tube, which makes it close and reliable.
3. Good resistance to atmospheric corrosion, stable long-term performance
