When bright annealing is used, pickling is not necessary. The pipe shall be made by the seamless or an automatic welding process, with no addition of filler metal in the welding operation.
Individual reprints single or multiple copies of this standard may be obtained by contacting ASTM at the above address asmt at phonefaxor service astm. The examination may not detect short, deep, defects.
Tension tests, hardening tests, flattening tests, hydrostatic tests and nondestructive electric tests shall be made to conform to the specified requirements. Within the text, the SI units are shown in brackets. The pipe shall be made by the seamless or an automatic welding process, with no addition of filler metal in the welding operation. This abstract is a brief summary of the referenced standard. Etching tests shall be made on a cross section from one end or both ends of each pipe and shall show sound and reasonably uniform material free of injurious laminations, cracks, and similar objectionable defects.
Aatm radiography is required. Within the text, the SI units are shown in brackets.
ASTM A790 Seamless and Welded Pipe
The dimensionless designator Nominal Pipe Size nominal pipe size has been substituted in this standard for such traditional terms as nominal diameter, size, and nominal size. These supplementary requirements call for additional tests to be made and, when desired, one or more of these may be specified in the order. Workmanship, Finish, and Appearance These supplementary requirements call for additional tests to be made and, when desired, one or more of these may be specified in the order.
Other 4 nondestructive tests may be applied to the end areas, subject to agreement between the purchaser and the manufacturer. Historical Version s – view previous versions of standard.

Duplex Steel and Pipe. A superscript epsilon e indicates an editorial change since the last revision or reapproval. Work Item s – proposed revisions of this standard. Extraneous signals caused by identiable causes such as dings, scratches, dents, asrm marks, and so forth shall not be considered noise.
Seamless austenitic pipe for high temperature applications.
Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. NOTE 2—This wstm applies when the inch-pound designation of this specication is the basis of purchase. The advantage of a duplex structure is that it combines the favorable qualities of a ferritic alloy stress corrosion cracking resistance and high strength with those of an austenitic alloy ease of fabrication and corrosion resistance.

Usually use Pitting Axtm Test. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. A number in parentheses indicates the year of last reapproval. More or smaller reference discontinuities, or both, may be used by agreement between the purchaser and the manufacturer.
Pipe shall be welded in one pass by processes employing filler metal and shall be completely radiographed.
