Chemical composition shall conform to the requirements. Elemental composition other than listed here shall not be permitted. Tension test, flattening test, flaring test, hardness test, hydrostatic or nondestructive electric test shall be made on specimens. Superheater tubes shall be formed without defects and shall withstand expansion, beading, forging, welding, and bending.

本规范涵盖无缝中碳钢锅炉和过热器管。该规范还涵盖了最小壁厚、管道尺寸、锅炉流量，包括安全端、拱形管和撑杆。该规范提供了拉伸和硬度性能，但仅适用于某些尺寸限制。管子应采用无缝工艺制造，标记为热加工或冷加工。订单中应明确说明表面状况。化学成分应符合要求。不允许使用此处未列出的元素成分。应对试样进行拉伸试验、平整试验、扩口试验、硬度试验、静水压试验或无损电气试验。过热器管应无缺陷，并应能承受膨胀、卷边、锻造、焊接和弯曲。

Scope范围

1. 1. This specification2 covers minimum-wall-thickness, seamless medium-carbon steel, boiler tubes and boiler flues, including safe ends (see Note 1), arch and stay tubes, and superheater tubes.

1.1本规范涵盖了最小壁厚、无缝中碳钢、锅炉管和锅炉流量，包括安全端（见注释1）、拱形管和斜撑管以及过热器管。

NOTE 1: This type is not suitable for safe ending by forge welding.

注1：这种类型不适合通过锻焊进行安全端接。

1. 2. The tubing sizes and thicknesses usually furnished to this specification are 1/2 in. to 5 in. [12.7 to 127 mm] in outside diameter and 0.035 to 0.500 in. [0.9 to 12.7 mm], inclusive, in minimum wall thickness. Tubing having other dimensions may be furnished, provided such tubes comply with all other requirements of this specification.

1.2本规范中通常提供的管材尺寸和厚度为外径1/2英寸至5英寸[12.7至127毫米]，最小壁厚0.035至0.500英寸[0.9至12.7毫米]。可以提供具有其他尺寸的管子，前提是这些管子符合本规范的所有其他要求。

1. 3. Mechanical property requirements do not apply to tubing smaller than 1/8 in. [3.2 mm] in inside diameter or 0.015 in. [0.4 mm] in thickness.

1.3机械性能要求不适用于内径小于1/8英寸[3.2毫米]或厚度小于0.015英寸[0.4毫米]的管子。

1. 4. This specification covers grades A-1 and C of Seamless Medium-Carbon Boiler and Superheater Tubes with different chemical and tensile requirements. (Table 1, Table 3, and Section 11.)

1.4本规范涵盖了具有不同化学和拉伸要求的A-1和C级无缝中碳锅炉和过热器管。（表1、表3和第11节。）

1. 5. The values stated in either inch-pound units or SI units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. Combining values from the two systems may result in nonconformance with the specification. The inch-pound units shall apply unless the “M” designation of this specification is specified in the order.

1.5以英寸-磅单位或国际单位表示的值应单独视为标准值。在文本中，国际单位制显示在括号中。每个系统中所述的值不是完全等效的；因此，每个系统都必须独立使用。将两个系统的值结合起来可能会导致不符合规范。除非订单中指定了本规范的“M”名称，否则应采用英寸-磅单位。

1. 6. 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.

1.6本国际标准是根据世界贸易组织技术性贸易壁垒委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认的标准化原则制定的。
