Unless specically called out by the purchaser, the selection of the nondestructive electric test shall be at the option of the manufacturer.

ASTM A999 for Alloy and Stainless Steel Pipe

The test system settings may be asym, or the transducer scoil s or sensor s adjusted, and the unit restandardized, but all pipe tested since the last asym standardization must be retested for acceptance. Standard Weight Weight per Unit Length 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. The holes shall be drilled radially and completely through the pipe wall, with care being taken to avoid distortion of the pipe while drilling.

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 axtm this standard to establish appropriate safety and health a9999 and determine the applicability of regulatory limitations prior to use.

The area producing the signal may be reexamined. In the case of conflict between a requirement of a product specification and a requirement of this specification, the product specification shall prevail.

ASTM A for Alloy and Stainless Steel Pipe

Historical Version s – view previous versions of standard. The pipe may be accepted based on visual examination provided that the imperfection is less than 0. Permissible Variations in Wall Thickness 9.

Notches shall be placed on both the OD and ID surfaces.

With the text, the SI units are shown in brackets. Nonconformance will be cause for the rejection of the lot. A superscript epsilon e indicates an editorial change since the last revision or reapproval. The minimum wall thickness on inspection is shown in Table X1. For welded pipe, a99 test pressure shall be held for a time sufficient to permit the entire length of the welded seam to be inspected.

The sensitivity of this test decreases with thickness over 0. 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.

There shall be no variation under the specied wall thickness. Combining values from the two systems may result in nonconformance with the specication. Permissible Variations in Length The inch-pound units apply unless the “M” designation SI of the product specification is specified in the order.

The tolerances on outside diameter include ovality except as provided for in The methods used for cleaning and preparing the surfaces for examination shall not be detrimental to the base metal or the surface nish.
