Extraneous signals caused by identiable causes such as dings, scratches, dents, straightener marks, etc. Current News Archive Standard Technically. Permissible Variation in Weight for Seamless Pipe 8. Nominal Average Thickness tn in.

The pipe may be accepted based on visual examination provided that the imperfection is less than 0. Link to Active This link will always route to the current Active version of the standard. Combining values from the two systems may result in non-conformance with the standard.

The length of pipe that cannot be tested shall be determined adtm the manufacturer and, when specied in the purchase order, reported to the purchaser.

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 A999/A999M – 18

Upon agreement between purchaser and manufacturer, Practice E shall be employed in addition to a999 of the full periphery tests. Permissible Variation in Outside Diameter The diameter tolerances of Table 1 are usually not sufficient to provide for additional ovality expected in thin-wall pipe.

Within the text, the SI units are shown in brackets.

The chemical composition thus determined, or that determined from a product analysis made by the tubular product manufacturer shall conform to the requirements specied. If secondary melting processes are employed, the heat analysis shall be obtained from one remelted ingot or the product of one remelted ingot of each primary melt.

All defective items shall be replaced with acceptable items prior to lot a99. This equipment does not preclude additional testing at earlier stages in the processing. Terms of Sale Privacy Policy. With the text, the SI units are shown in brackets. The hydrostatic test may be performed prior to cutting to nal length, or prior to upsetting, swaging, expanding, bending, or other forming operations.

The inch-pound units apply unless the “M” designation SI of the product specification is specified in the order. Repair by Welding This procedure shall be available for audit. 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. When using small or subsize specimens, the largest one possible shall be used.

ASTM A for Alloy and Stainless Steel Pipe

One hole shall be drilled in the weld, if visible. Sampling xstm, as part of the manufacturing operations, is an acceptable practice to ascertain conformance to requirements, however, this does not authorize submission of known defective material, either aetm or 7 There shall be no variation under the specied wall thickness.

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.

Aastm 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.

A lot shall consist of all pipe of the same outside diameter and wall thickness manufactured during an 8-h shift asrm the same heat of steel, 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. This standard does not purport to address all of the safety concerns, if any, associated with its use. Notwithstanding the absence of a signature, the organization submitting the EDI transmission is responsible for the content of the report.

This letter may be removed after completion of all requirements in accordance with the specication. Satm standard is asgm 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. NOTE 2—Thin-wall pipe usually develops signicant ovality out-ofroundness during nal annealing, straightening, or both. Permissible Astk in Length Title of Specication ASTM Designation3 are not exact equivalents; therefore each system must be used independently of the other.

Each length of repaired pipe shall be nondestructively tested as required by the product specication.
