For pipe larger than NPS 4 [DN ], where individual lengths are weighed, the weight mass tolerance is exceeding For pipe NPS 2 exceeding The minimum wall thickness on inspection shall the method being used. End Finish reference notches shall be straight-sided notches machined in a radial plane parallel to the pipe axis. For specified wall For specified wall thicknesses equal to or The notch depth shall not exceed Outside diameter and in wall thickness less than 0.
For standard-weight pipe NPS same specification test to which it was originally subjected and 6 [DN ] or smaller, refer to Table X3. It shall be permis- sizes of extra-strong weight pipe and double extra-strong sible to reduce the outside diameter at the point of grinding by weight pipe, refer to Table X3.
Threaded the amount so removed. A few examples of such imperfections are pipe shall be provided with a coupling manufactured in straightener marks, cutting chips, scratches, steel die stamps, accordance with Specification A The coupling threads stop marks, or pipe reducer ripple. The coupling shall be applied handling-tight, unless measured as the gap between the lowest point of the dent and power-tight is specified in the purchase order. Couplings are to a prolongation of the original contour of the pipe.
Cold-formed be made of steel. The length of the dent in any direction shall tapped couplings for extra-strong and double extra-strong not exceed one half the specified outside diameter of the pipe.
If taper-tapped couplings are required for The taper-tapped couplings pro- specified in Section 7 shall be made on test specimens taken vided on line pipe in such sizes may be used on mill-threaded from one length of pipe from each lot of each pipe size. For standard-weight pipe of the same size. For seamless and electric- Pipe with defects welded pipe shall be in accordance with 7.

Only one retest of any lot will be permitted. Any Any individual length of pipe that does not not scattered, but appear over a large area in excess of what is conform to the test requirements may be resubmitted for test considered a workmanlike finish.
Disposition of such pipe shall and will be considered acceptable if tests taken from each pipe be a matter of agreement between the manufacturer and the end conform to the specified requirements. It shall be permissible to reduce the outside the same weld orientation as the failed test and a satisfactory diameter at the point of grinding by the amount so removed.
In the case of a dispute, Individual lengths are considered acceptable Test Methods Test specimens for flattening tests shall be one from each end of one length of galvanized pipe selected at smooth on the ends and free from burrs.

Certification The the material has been manufactured, sampled, tested, and location of such marking shall be at the option of the inspected in accordance with this specification including manufacturer.
Product Marking standard prepared by the Primary Metals Subcommittee of the Government Procurement show: The applicable levels shall be as specified in NOTE 8—Pipe that complies with multiple compatible specifications the contract. Marking for shipment of such pipe shall be in may be marked with the appropriate designation for each specification. Except as The purchaser shall have the right to perform any of the purchase order, length shall be marked in feet and tenths of a inspections and tests set forth in this specification where foot, or metres to two decimal places, dependent upon the units deemed necessary to ensure that the pipe conforms to the to which the pipe was ordered.
The location of such marking specified requirements. Packaging and Package Marking Yes No Test pressure The purchaser may specify a different frequency of test than is provided in the supplementary requirement. Subject to agreement between the purchaser and manufacturer, retest and retreatment provisions of these supplementary requirements may also be modified. Flattening Test, Seamless Pipe S1. During S1. Only one retest of any the flattening shall be continued until the test specimen breaks lot will be permitted.
Any individual length of pipe that or the opposite sides of the test specimen meet. Evidence of conforms to the test requirements is acceptable. Any individual laminated or unsound material that is revealed during the entire length of pipe that does not conform to the test requirements flattening test shall be cause for rejection.
It is manufactured by hot working steel and, if necessary, X1. Thickness, in. The computed test pressure shall be used in all cases, except as follows: 1 For specified wall thicknesses greater than the heaviest specified wall thickness listed in this table for the applicable specified outside diameter, the test pressure shall be the highest value listed for the applicable specified outside diameter and grade.
Test pressures for intermediate specified outside diameters need not exceed those given in this table for the next larger listed size. The wall thickness is expressed to three [two] decimal places, the fourth [third] decimal place being carried forward or dropped in accordance with Practice E NOTE 2—This table is a master table covering wall thicknesses available in the purchase of different classifications of pipe, but it is not meant to imply that all of the walls listed therein are obtainable under this specification.
