Embedded fin pull test

- Spacing of two fins to come to present the third fin on which the test will be applied
- Cutting at 90 °

- Applied a measuring device on the “cut”

- Tightening of the fin “cut” into a jaw

- Manual traction from bottom to top

- Reading on the dial (kg)

 

Embedded fins dimensional control

Length: with a meter inside the tube and measured from one extremity to the other.

Diameter : with a caliper (tube and fins)

Left side & right side length : with a meter

Number of fins : with a special rule
