Notes:

»
|
Weight and allowable stress calculations are based on material
density of 490 pcf density and a modulus of elasticity (E) of 29,000 ksi
[steel].
|
|
»
|
Buoyancy calculations based on a pipe submerged in seawater
(64.2 pcf
density). Note: Full buoyancy reported in table
above will not occur for open-ended pipes.
|
|
»
|
Pipe allowable stresses based on American Petroleum
Institute Recommended Practice 2A - Working Stress Design (API RP 2A-WSD)
21st Edition.

»
|
The "lb", "kg", and "ksi" (kips/sq. in.) units noted in
the table above
are actually "lbf", "kgf", and 1000 lbf/sq. in (where
1000 lbf = 1 kip).

» How do I use this calculator?
|
1. |
Select units of your input data.
|
|
2. |
Enter pipe diameter and thickness data.
|
|
3. |
Click on the "calculate" button and section property results
will be displayed in the "results" table. |
|
4. |
Optional input includes the pipe yield strength, pipe length and
K-factor: |
|
|
 |
For allowable bending stress, enter the pipe yield
strength in addition to the diameter and thickness. |
|
|
For allowable axial stress, enter the yield strength, length,
and K-factor in addition to the diameter and thickness.
