The steel categorized in this standard must be open-hearth, basic-oxygen or electric-furnace processed and must have the following chemical requirements: The tubing shall undergo a seamless or welding process. Tension, bend, and flattening tests shall be performed to make sure that it must adhere to a553m mechanical properties of the standard.
ASTM A53 / A53M Standard specification
a5m3 The hydrostatic test shall be applied, without leakage through the weld seam or the pipe body. Nondestructive electric test shall be made asgm make sure that the full volume of the pipe must be in accordance with the standard.
The purchaser shall have the right to perform any of the inspections and tests set forth in this specification where deemed necessary to ensure that the pipe conforms to the specified requirements. It shall be permissible to furnish pipe having other dimensions provided that such pipe complies with all other requirements of this specification. Supplementary requirements of an optional nature are provided and shall apply only when specified by the purchaser.
Note 3—See Appendix X1 for definitions of types of pipe.
It is suitable for welding, and suitable for forming operations involving coiling, bending, and flanging, subject to the following qualifications: The values stated in aastm system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard. This standard does not purport to address all of the safety concerns, if any, associated with its use.
It is the responsibility of the user of this standard to establish qstm safety and health practices and determine the applicability of regulatory requirements prior to use. Such notes and footnotes, excluding those in tables and figures, do not contain any mandatory requirements.
This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its ashm and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.
It shall be permissible to furnish pipe having other dimensions provided such pipe complies with all other requirements of this specification. Pipe ordered under this specification shall be suitable for bending, flanging, and similar forming operations, and for welding. When the steel is to be welded, it is presupposed that a welding procedure suitable to the grade of steel and intended use or service will be utilized.
It is suggested, consideration be given to possible graphitization. These supplementary requirements call for additional tests to be made and when desired shall be so stated in the order. 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 A53 – Wikipedia
This specification covers seamless carbon steel pipe for high-temperature service Sizes Seamless: Schedule 20 — Schedule XXS heavier on request up w53m mm thickness. Sets standards for coating of pipe with zinc inside and outside by the hot-dipped process. Weight of coating must not average less than 1. The minimum wall thickness at any point shall not be more than Seamless and Electric-Resistance-Welded — Bending, flattening, tensile on one length of pipe from each lot of lengths or less of a size.
Continuous-Weld — Bending, flattening, tensile.
Hydrostatic inspection test pressures for plain end and threaded and coupled pipe are specified. Hydrostatic pressure shall be maintained for not less than 5 seconds for all sizes of seamless and electric-resistance-weld pipe.
