The test system settings may be adtm, 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 manufacturer shall afford the inspector all reasonable facilities to satisfy him that the material is being furnished in accordance with this specication.
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. The pipe may be accepted based on visual examination provided that the imperfection is less than 0. When using small or subsize specimens, the largest one possible shall be used. Defects shall be thoroughly chipped or ground out before welding and each repaired length shall be reheat treated or stress relieved as required by the applicable specication.
In the case of conict between a requirement of the product specication or a requirement of this specication and a more stringent requirement of the purchase order, the purchase order shall prevail.
During the second step, which is a test for soundness, the attening shall be continued until the specimen breaks or the opposite walls of the pipe meet. NOTE 4—Notwithstanding the absence of a signature or notarization, the organization submitting the Report is responsible for the contents of the report. All defective items shall be replaced with acceptable items prior to lot acceptance.
Unless specically called out by the purchaser, the selection of the nondestructive electric test shall be at the option q999 the manufacturer. Current News Archive Standard Technically. 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. If you feel 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.
Extraneous signals caused by identiable causes such as dings, scratches, dents, straightener marks, etc. There shall be no variation under the specied wall thickness. 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.
It should be recognized that different techniques should be used to detect differently oriented imperfections. The aatm sizes do not prohibit the production and use of other sizes asttm pipe produced to the various product specications referenced in 1. All required 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.
The tolerances on outside diameter include ovality except as provided for in Marking shall begin approximately 12 in. Rejected lots may be screened and resubmitted for axtm and dimensional examination. Only one retest of any lot will be permitted. Individual reprints single or a9999 copies of this standard may be obtained by contacting ASTM at the above address or at phonefaxor service astm. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
With the text, the SI units are shown in brackets.
Nonconformance will z999 cause for the rejection of the lot. Other nondestructive tests may be applied to the end areas, subject to agreement between the purchaser and the manufacturer.
Test data from a minimum of three test lots, as dened by the specication, each from a different heat, shall be furnished. 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. In the case of conflict between a requirement of a product specification and a requirement of this specification, the product specification shall prevail.
A superscript epsilon e indicates an editorial change since the last revision or reapproval. Combining values from the two systems may result in non-conformance with the standard. Work Item s – proposed revisions of this standard.
This specification Footnote 2 covers a group of general requirements that, unless otherwise specified in an individual specification, shall apply to the ASTM product specifications noted below. Standard Weight Weight per Unit Length During the rst step, which is a test for ductility, no cracks or breaks on the inside or outside surfaces, except as provided for in In the case of conflict between a requirement of the product specification or 9a99 requirement of this specification and a more stringent requirement of the purchase order, the purchase order shall prevail.
For pipe less than NPS aztm 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. Upon agreement between purchaser and manufacturer, Practice E shall be employed in addition to one of the full periphery tests.
Permissible Variations in Inside Diameter 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.
The diameter tolerances of Table 1 are usually not sufficient to provide for additional ovality expected in thin-wall pipe. A lot shall consist of all pipe of the same outside diameter and wall thickness manufactured during an 8-h shift from the same heat of asgm, and heat treated under the same conditions of temperature and time in a single charge in a batch type furnace, or heat treated under the same condition in a continuous furnace, and presented for inspection at the same time.
ASTM A for Alloy and Stainless Steel Pipe
Axtm 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.
On specied walls up to 0. A signature or notarization is not required on the certied test report, but the document shall be dated and shall clearly identify the organization submitting the report.
ASTM Desig- nation 3. 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. A Maximum Curvature in any 3 ft, in.
