Mechanical Tests Specified
| Transverse or Longitudinal Tension Test and Flattening Test, Hardness Test, or Bend Test |
| For material heat treated in a batch-type furnace, tests shall be made on 5% of the pipe from each treated lot. For small lots, at least one pipe shall be tested. |
| For material heat treated by the continuous process, tests shall be made on a sufficient number of pipe to constitute 5% of the lot, but in no case less than 2 pipe. |
| Notes for Hardness Test: |
P91 shall not have a hardness not exceeding 250 HB/265 HV [25HRC]. |
| Notes for Bend Test: |
For pipe whose diameter exceeds NPS 25 and whose diameter to wall thickness ratio is 7.0 or less shall be subjected to the bend test instead of the flattening test. |
|
Other pipe whose diameter equals or exceeds NPS 10 may be given the bend test in place of the flattening test subject to the approval of the purchaser. |
|
The bend test specimens shall be bent at room temperature through 180 without cracking on the outside of the bent portion. |
|
The inside diameter of the bend shall be 1 inch [25 mm]. |
| Hydrostatic Test |
Each length of pipe shall be Hydro tested, at option of manufacture nondestructive electric testing can be used. |
