The chemical composition thus determined, or that determined from a product analysis made by the tubular product manufacturer shall conform to the requirements specied. The range of pipe sizes that may a9999 examined by each method shall awtm subject to the limitations in the scope of the respective practices.

A Maximum Curvature in any 3 ft, in. The absence of any inspection requirements in the specication shall not relieve the contractor of the responsibility for ensuring that all products or supplies submitted to the government adtm acceptable comply with all requirements of the contract. 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 material, either indicated or 7 The manufacturer may reheat treat the pipe, but not more than twice, except with the approval of q999 purchaser.

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. Marking shall begin approximately 12 in.

ASTM A for Alloy and Stainless Steel Pipe

It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. ASTM Desig- nation 3. Nonconformance will be cause for the rejection of the lot.

The holes shall be drilled radially and completely through the pipe wall, with care being taken to avoid distortion of the pipe while drilling.


For metal-arc welded pipe with lengths shorter than 10 ft [3. This does not prohibit testing at higher pressures at the option of the manufacturer or as provided in 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 Length During the rst step, which is a test for ductility, no cracks or breaks on the inside, outside, or end surfaces, except as provided for in The outside diameter at the point of grinding may be reduced by the amount so removed. 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.

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.

Permissible Variation in Weight for Seamless Pipe 8.

Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. Standard Weight Weight per Unit Length Notwithstanding the absence of a signature, the organization submitting the EDI transmission is responsible for the content of the report.

Permissible Variations in Wall Thickness 9. Permissible Variations in Inside Asstm Nondestructive Test Requirements 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. Notches shall be placed on both the OD and ID surfaces.

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. Defects shall be thoroughly chipped or ground out before welding and each repaired length shall be reheat treated w999 stress relieved as required by the applicable specication.


Other nondestructive tests may be applied to the end areas, subject to agreement between the purchaser and the manufacturer. Certied Test Report Ast, equipment does not preclude additional testing at earlier stages in the processing.

ASTM A999/A999M – 18

Title of Specication ASTM Designation3 are not exact equivalents; therefore each system must be used independently of the other. The tolerances on outside diameter include ovality except as provided for in For welded pipe, the test pressure shall be held for a time sufficient to permit the entire length of the welded seam to be inspected.

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. Disposition of such pipe shall be matter for agreement. Within the text, the SI units are shown in brackets. Nominal Average Thickness tn in.

The diameter tolerances of Table 1 are usually not sufficient to provide for additional ovality expected in thin-wall pipe. The test pressure or stress shall be determined by the following equation: A9999Columbus, OH — Combining values from the two systems may result in non-conformance with the standard.

Disposition of rejected pipe shall be a matter of agreement between the manufacturer and the purchaser. The sensitivity of this test decreases with thickness over 0. Current News Archive Standard Astk. The pipe may be accepted based on visual examination provided that the imperfection is less than 0.

ASTM D e1. All defective items shall be replaced with acceptable items prior to lot acceptance. Work Item s – astmm revisions of this standard. NOTE 2—Thin-wall pipe usually develops signicant ovality out-ofroundness during nal annealing, straightening, or both.
