One hole shall be drilled in the weld, if visible. This procedure shall be available for audit.
Within the text, the SI units are shown in brackets. The test system settings may be changed, or the transducer scoil s or sensor s adjusted, and the unit restandardized, but all pipe tested since the last acceptable standardization must be retested for acceptance. The inch-pound units apply unless the “M” designation SI of the product specification is specified in the order.
If secondary melting processes are employed, the heat analysis shall be obtained from one remelted ingot a9999 the product of one remelted ingot of each primary melt. The bottom of imperfections shall be visible and the prole shall be rounded and faired-in.
ASTM A for Alloy and Stainless Steel Pipe
Only one retest of any lot will be permitted. This standard does not purport to address all of the safety concerns, if any, associated with its use. Individual lengths that do not conform to the test requirements may be resubmitted for test provided the reason for nonconformance is established and the nonconforming portion removed.
Extraneous signals caused by identiable causes such as dings, scratches, dents, straightener marks, etc. Sampling inspection, as part of the manufacturing operations, is an acceptable practice to ascertain conformance to requirements, however, this does not authorize submission of known defective w999, either indicated or 7 If you a9999 that your comments have not received a fair hearing you should make your views known to the ASTM Committee on Standards, at the address shown below.
Flattening Test Requirements Defects shall be thoroughly chipped or ground out before welding and each repaired length shall be reheat treated or stress relieved as required by a9999 applicable specication. Work Item s – proposed revisions of this standard.
Individual reprints single or multiple copies of this standard may be obtained by contacting ASTM at the above address or at phonefaxor service astm. Disposition of rejected pipe shall be a matter of agreement between the manufacturer and the purchaser.
Within the text, the SI units are shown in brackets. Nondestructive Test Requirements NOTE 4—Notwithstanding the absence of a signature or notarization, the organization submitting the Report is responsible for the contents of the report. Disposition of such pipe shall be matter for agreement.
Unless specically called out by the purchaser, the selection of the nondestructive electric test shall be at the option of the manufacturer. The manufacturer may reheat treat the pipe, but not more than twice, except with the approval of the purchaser. 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.
All defective items shall be replaced with acceptable items prior to lot acceptance. Current edition approved March 10, The outside diameter at the point of grinding may be reduced by the amount so removed. Rejected lots may be screened and resubmitted for visual and dimensional examination. These requirements shall take precedence if there is a conict between these requirements and the product specication.
All adtm tests and inspection shall be made at the place of manufacture prior to shipment, unless otherwise specied, and shall be conducted so as not to interfere unnecessarily with operation of the works. This does not prohibit testing at higher pressures at the option of the manufacturer or as provided in NOTE 2—Thin-wall pipe usually develops signicant ovality out-ofroundness during adtm annealing, straightening, or both.
ASTM A999 for Alloy and Stainless Steel Pipe
The dimensions of these standards should not be construed as the minimum size imperfection detectable by such equipment. There shall be no variation over the specied inside diameter.
The examination may not detect short deep defects. 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 the applicable product specication. The pipe may be accepted based on visual examination provided that the imperfection is less than 0.
