This specification covers seamless medium-carbon steel boiler and superheater tubes. The specification also covers minimum-wall-thickness, tubing sizes, boiler flues including safe ends, arch and stay tubes. The specification provides tensile and hardness properties but only applicable to certain size limitations. Material manufacturing shall be killed. Tubes shall be made by seamless process, marked as either hot-finished or cold-finished. Surface condition shall be specifically stated in the order. 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.

本規(guī)范涵蓋無縫中碳鋼鍋爐和過熱器管。該規(guī)范還涵蓋了最小壁厚、管道尺寸、鍋爐流量，包括安全端、拱形管和撐桿。該規(guī)范提供了拉伸和硬度性能，但僅適用于某些尺寸限制。管子應(yīng)采用無縫工藝制造，標(biāo)記為熱加工或冷加工。訂單中應(yīng)明確說明表面狀況?；瘜W(xué)成分應(yīng)符合要求。不允許使用此處未列出的元素成分。應(yīng)對試樣進行拉伸試驗、平整試驗、擴口試驗、硬度試驗、靜水壓試驗或無損電氣試驗。過熱器管應(yīng)無缺陷，并應(yīng)能承受膨脹、卷邊、鍛造、焊接和彎曲。

Scope范圍

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本規(guī)范涵蓋了最小壁厚、無縫中碳鋼、鍋爐管和鍋爐流量，包括安全端（見注釋1）、拱形管和斜撐管以及過熱器管。

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

注1：這種類型不適合通過鍛焊進行安全端接。

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本規(guī)范中通常提供的管材尺寸和厚度為外徑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]?？梢蕴峁┚哂衅渌叽绲墓茏樱疤崾沁@些管子符合本規(guī)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機械性能要求不適用于內(nèi)徑小于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本規(guī)范涵蓋了具有不同化學(xué)和拉伸要求的A-1和C級無縫中碳鍋爐和過熱器管。（表1、表3和第11節(jié)。）

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-磅單位或國際單位表示的值應(yīng)單獨視為標(biāo)準(zhǔn)值。在文本中，國際單位制顯示在括號中。每個系統(tǒng)中所述的值不是完全等效的；因此，每個系統(tǒng)都必須獨立使用。將兩個系統(tǒng)的值結(jié)合起來可能會導(dǎo)致不符合規(guī)范。除非訂單中指定了本規(guī)范的“M”名稱，否則應(yīng)采用英寸-磅單位。

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本國際標(biāo)準(zhǔn)是根據(jù)世界貿(mào)易組織技術(shù)性貿(mào)易壁壘委員會發(fā)布的《關(guān)于制定國際標(biāo)準(zhǔn)、指南和建議的原則的決定》中確立的國際公認(rèn)的標(biāo)準(zhǔn)化原則制定的。
