ASTM A53/A53M黑色和熱浸鍍鋅焊接和無縫鋼管標準規範。

This specification covers seamless and welded black and hot-dipped galvanized steel pipe in NPS 1/8 to NPS 26. The steel categorized in this standard must be open-hearth, basic-oxygen or electric-furnace processed and must have the following chemical requirements: carbon, manganese, phosphorus, sulfur, copper, nickel, chromium, molybdenum, and vanadium. 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 the mechanical properties of the standard. The hydrostatic test shall be applied, without leakage through the weld seam or the pipe body. Nondestructive electric test shall be made to 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.

本規範涵蓋NPS 1/8至NPS 26的無縫焊接黑色熱浸鍍鋅鋼管。本標準中分類的鋼必須是平爐、堿性氧氣或電爐加工的，並且必須具有以下化學要求：碳、錳、磷、硫、銅、鎳、鉻、鉬和釩。管子應經過無縫或焊接工藝。應進行拉伸、彎曲和壓扁試驗，以確保其必須符合標準的機械性能。應進行水壓試驗，焊縫或管體不得泄漏。應進行無損電氣試驗，以確保管道的全部體積必須符合標準。買方有權在必要時進行本規範中規定的任何檢查和測試，以確保管道符合規定的要求。

Scope範圍

1.1 This specification2 covers seamless and welded black and hot-dipped galvanized steel pipe in NPS 1/8 to NPS 26 [DN 6 to DN 650] (Note 1), inclusive, with nominal wall thickness (Note 2) as given in Table X2.2 and Table X2.3. 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.

1.1本規範2涵蓋NPS 1/8至NPS 26[DN 6至DN 650]（含）的無縫焊接黑色熱浸鍍鋅鋼管，公稱壁厚（注2）如表X2.2和表X2.3所示。允許提供具有其他尺寸的管道，前提是此類管道符合本規範的所有其他要求。提供了可選性質的補充要求，僅在買方指定時適用。

NOTE 1: The dimensionless designators NPS (nominal pipe size) [DN (diameter nominal)] have been substituted in this specification for such traditional terms as “nominal diameter,” “size,” and “nominal size.”

注1：本規範中用無量綱指示符NPS（公稱管道尺寸）[DN（公稱直徑）]代替了“公稱直徑”、“尺寸”和“公稱尺寸”等傳統術語

NOTE 2: The term nominal wall thickness has been assigned for the purpose of convenient designation, existing in name only, and is used to distinguish it from the actual wall thickness, which may vary over or under the nominal wall thickness.

注2：術語“標稱壁厚”是為了便於命名而指定的，僅存在於名稱中，用於將其與實際壁厚區分開來，實際壁厚可能在標稱壁厚之上或之下變化。

1.2 This specification covers the following types and grades: 本規範涵蓋以下類型和等級：

1.2.1 Type F—Furnace-butt-welded, continuous welded Grades A and B,  F型——爐對接焊接，A級和B級連續焊接，

1.2.2 Type E—Electric-resistance-welded, Grades A and B, and E型——電阻焊，A級和B級，以及

1.2.3 Type S—Seamless, Grades A and B.  S型——無縫，A級和B級。

NOTE 3: See Appendix X1 for definitions of types of pipe.  注3：管道類型的定義見附錄X1。

1.3 Pipe ordered under this specification is intended for mechanical and pressure applications and is also acceptable for ordinary uses in steam, water, gas, and air lines. It is suitable for welding, and suitable for forming operations involving coiling, bending, and flanging, subject to the following qualifications:

1.3根據本規範訂購的管道適用於機械和壓力應用，也可用於蒸汽、水、氣體和空氣管線的普通用途。它適用於焊接，也適用於涉及卷取、彎曲和翻邊的成型操作，但須符合以下資格：

1.3.1 Type F is not intended for flanging.F型不適用於翻邊。

1.3.2 When pipe is required for close coiling or cold bending, Grade A is the preferred grade; however, this is not intended to prohibit the cold bending of Grade B pipe.

1.3.2當管道需要進行密卷或冷彎時，A級是首選等級；然而，這並不是為了禁止B級管道的冷彎。

1.3.3 Type E is furnished either nonexpanded or cold expanded at the option of the manufacturer.

1.3.3 E型可由製造商選擇非膨脹或冷膨脹。

1.4 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each 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.

1.4以國際單位製或英寸-磅單位表示的值應單獨視為標準值。每個係統中所述的值可能不是完全等效的；因此，每個係統都應獨立使用。將兩個係統的值結合起來可能會導致不符合標準。

1.5 The following precautionary caveat pertains only to the test method portion, Sections 7, 8, 9, 13, 14, and 15 of this specification: 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 appropriate safety, health, and environmental practices and determine the applicability of regulatory requirements prior to use.

1.5以下預防性警告僅適用於本規範第7、8、9、13、14和15節的測試方法部分：本標準並不旨在解決與其使用相關的所有安全問題（如果有的話）。本標準的使用者有責任在使用前建立適當的安全、健康和環境實踐，並確定監管要求的適用性。

1.6 The text of this specification contains notes or footnotes, or both, that provide explanatory material. Such notes and footnotes, excluding those in tables and figures, do not contain any mandatory requirements.

1.6本規範的文本包含注釋或腳注，或兩者兼而有之，提供解釋性材料。此類注釋和腳注（不包括表格和圖表中的注釋和腳注）不包含任何強製性要求。

1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

1.7本國際標準是根據世界貿易組織技術性貿易壁壘委員會發布的《關於製定國際標準、指南和建議的原則的決定》中確立的國際公認的標準化原則製定的。
