Hot rolled And Cold Drawn Mechanical Tubing Cleanups
For Full Surface Integrity And Base Metal
Formulas for calculating surface cleanup:
HR - OD Cleanup = [.022e.18 OD]
CD - OD Cleanup = .86[.022e.18 OD]
HR - CD - ID Cleanup = .78[.022e.18 OD]
Formulas for calculating camber (Straightness) cleanup:
Chucked on one end:
- Part length 3 inches or less-no camber added
Part length 3 inches-double the part length to calculate camber.
Chucked on both ends:
- Length 6 inches or less-no camber added
Length over 6 inches-use formulas below (do not double part length).
Formulas (Calculate all length dimensions in inches):
| A. OD < 5.000 inches = |
(171 x length) - 444 - (1.03 x length squared) |
|
| 100,000 |
| B. OD 5.000 inches = |
(222 x length ) - 222 - (1.13 x length squared) |
|
| 100,000 |
| C. OD < 5.000 inches and Part Length > 60 inches = |
450 + (25 x length) |
|
| 30,000 |
| D. OD 5.000 inches and Part Length > 60 inches: Use formula C + .030 inches |
