Training Tips:

Question:
How to find out what the finished ID should be after rolling a tube before carrying out a pullout test.

Even if you are not carrying out pullout tests you should know the finished ID of the rolled tubes so this can be checked as the rolling of the tubes proceed.

Example:
1.250"OD x 0.105" wall thickness
Recommended expansion 0.009"
Tube Sheet Hole 1.260"

1. Tube ID before Expansion 1.040"

2. Recommended expansion 0.009"

3. Difference between Tube OD
and Tube Sheet Bore Hole     0.010"

Finished ID (Add1,2,and 3)    1.059"
