Upon agreement between purchaser and manufacturer, Practice E shall be employed in addition to one of the full periphery tests.
Standard Weight Weight per Unit Length A number in parentheses indicates the year of last reapproval.
The examination may not detect short deep defects. Combining values from the two systems may result in nonconformance with the specication.
Packaging, Marking, and Loading This standard does not purport to address all of the safety concerns, if any, associated with its use.
However, sensitivity of the test to various types of discontinuities is affected by the calibration, and different techniques should be employed to detect differently oriented imperfections.
Permissible Variations in Wall Thickness 9. A superscript epsilon e indicates an editorial change since the last revision or reapproval. It should be recognized that different techniques should be used to detect differently oriented imperfections.
The internal surface of hot nished ferritic steel pipe shall be pickled or blast cleaned to a free of scale condition equivalent to the CSa2 visual standard in SSPC-SP6. Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM Headquarters.
The sensitivity of this test decreases with thickness over 0. These requirements shall take precedence if there is a conict between these requirements and the product specication.
Users of this standard are expressly advised that determination of the validity of any such patent rights, and the risk of infringement of such rights, are entirely their own responsibility.
This standard is subject to revision at any time by the responsible technical committee and must be reviewed every ve years and if not revised, either reapproved or withdrawn. One hole shall be drilled in the weld, if visible. To be accepted, retested pipe shall meet the test requirement.
Except as otherwise specied in the contract or purchase order, the manufacturer may use his own or any other suitable facilities for the performance of the inspection and test requirements unless disapproved by the purchaser at the time the order is placed.
Flattening Test Requirements The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. The range of pipe sizes that may be examined by each method shall be subject to the limitations in the scope of the respective practices.
A signature or notarization asrm not required on the certied test report, but the document shall be dated and shall clearly identify the organization submitting the report.
To be accepted, a repaired pipe must pass the same nondestructive test by which it was rejected, and it must meet the minimum wall thickness requirements of asm applicable product specication.
ASTM A999 for Alloy and Stainless Steel Pipe
If secondary melting processes are employed, the heat analysis shall be obtained from one remelted ingot or the product of aatm remelted ingot of each primary melt. Notches shall be placed on both the OD and ID surfaces. For pipe less than NPS 2 and pipe under 3 ft [1 m] in length, the required information may be marked on a tag securely attached to the bundle or box in which the pipes are shipped.
The purchaser must certify that all requirements of the aatm have been completed before the removal of the letter that is, X, Y, or Z. Repair by Welding Other nondestructive tests may be applied to the end areas, subject to agreement between the purchaser and the manufacturer. In the case of conflict between a requirement of the product specification or a requirement of this specification and a more stringent requirement of the purchase order, the purchase order shall prevail.

ASTM Desig- nation 3. This equipment does not preclude additional testing at earlier stages in the processing. Nondestructive Test Requirements The purchaser shall have the right to perform any of the inspections and tests set forth when such inspections and tests are deemed necessary to ensure that the material to conforms to the prescribed requirements.
NOTE 2—Thin-wall pipe usually develops signicant ovality out-ofroundness during nal annealing, straightening, or both. Axtm welded pipe, the test pressure shall be held for a time sufficient to permit the entire length of the welded seam to be inspected.
This does not prohibit testing at higher pressures at the option of the manufacturer or as provided in It is the responsibility of the user of this standard astn establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
Such requirements to be considered include, but are not limited to, the following: Disposition of rejected pipe shall be a matter of agreement between the manufacturer and the purchaser. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
On specied walls up to 0. Permissible Variation in Weight for Seamless Pipe 8. Notwithstanding the absence of a signature, the organization submitting the EDI transmission is responsible for the content of the report. The tolerances on outside diameter include ovality except as provided for in This procedure a9999 be available for audit.
