BENDING TOLERANCES


Rotary Draw, Roll and Increment Bending Tolerances

Standard shop tolerances for rotary draw, roll and increment bending procedures are available upon request.



Spiral Bending Tolerances



Tolerances for Cold Spiral Bending
Plain view radius of 12'0" or less.

True Arc Length Plumb to Radius Line Torpedo Level Vertical Face Pitch in Degrees Height at Midpoint Height at Top
Under 10 ft +/- 12" Within 3° overall +/- 1° +/- 12" +/- 14"
10 ft - 17 ft +/- 34" Within 3 12° overall +/- 1° +/- 1" +/- 12"
17 ft - 24 ft +/- 1" Within 4° overall +/- 1 12° +/- 1 12" +/- 1"
Over 24 ft +/- 1" Within 5° overall +/- 1 12° +/- 2" +/- 1"
*To properly QC, all stringers are stood up at full scale pitch.


Tolerances for Cold Spiral Bending
Plain view radius greater than 12'0"

True Arc Length Plumb to Radius Line Torpedo Level Vertical Face Pitch in Degrees Height at Midpoint Height at Top
Under 10ft See Note 1 Within 3° overall +/- 1° n/a n/a
10 ft - 17 ft See Note 1 Within 3 12° overall +/- 1° n/a n/a
17 ft - 24 ft See Note 1 Within 4° overall +/- 1 12° n/a n/a
Over 24 ft See Note 1 Within 5° overall +/- 1 12° n/a n/a
*To properly QC, all stringers are stood up at full scale pitch.

Notes:
1. Plumb to Radius line tolerance is Not Applicable. Instead, Albina will apply our standard shop cord and rise tolerances (available upon request).

I remember getting quotes and visiting the shop 30-some years ago and thought it was cool to watch the crew bend small pipe. Looking at these pictures shows how far your company has come. This is really interesting stuff! A guy would look forward to coming to work every day to do something this impressive. Keep up the wonderful work!

I have to say; communication with Albina, is as good as it gets. Clarity was key to success, and I like that your shop reviewed our drawings as well, prior to bending. Our expectations were met, and we were given notification in advance about any concerns.
