ASTM A213 Alloy Tubes

ASTM A213 Alloy Tubes are been widely used in high temperature services especially for the boiler and superheater.

ASTM A213 T91管的PMI测试

ASTM A213合金管材料可以使用合金钢和不锈钢，并用无缝的热卷或冷水制成。因此，该管道通常在非常重要的地方使用，价格比普通碳管高得多。

阳光明媚的钢Supply stocks a full range of the following ASTM A213 grades:

主要等级：ASTM A213 T5，T5B，T9，T11，T91和T22

Size range:

NPS 1/4'' to NPS 24''
壁厚 - 时间表40至160，STD，XS，XXS。
Unscheduled heavy wall pipe thicknesses available up to 4 inches.

SA 213 standard specification for seamless ferritic and austenitic alloy-steel boiler,super heater,and heat-exchanger tubes.

1.表面状态：
Austenitic steel pipe should be washed to remove the scale, when the use of bright annealing, you do not need pickling.

2.成品的化学分析：
It shall be analyzed from one billet or one pipe per furnace, and the chemical composition determined accordingly shall meet the specified requirements.

3. Mechanical test and grain size:
（1）拉伸测试：例如每批钢管≤50根，然后取一个样品进行拉伸测试；每批钢管> 50，然后两个钢管应服用两个样品进行拉伸测试。
(2) Flattening test: in each batch of a finished tube at both ends of each sample to take a flattening test, but the root can not used as a flaring sample.
（3）耀斑测试：在样品两端的每批成品管中，进行燃烧测试，但根管不能用作平坦的样品。
（4）硬度测试：从样品上的每批两管中进行Brinell或Rockwell硬度测试。
（5）水压测试：每根管道应为静水测试。指定买家时，可以使用非破坏性测试。
(6) Grain size: according to ASME E112 standard test.

Seamless ferrite alloy and austenitized alloy tubes

1.1该规范涵盖了无缝铁素体和奥斯丁钢锅炉，过热器和热量交换器，指定的级T91，TP304等。这些钢列在表1和2中。

1.2包含字母H的等级为H中，其指定要求与不包含字母的类似成绩的要求不同。这些不同的要求提供的蠕变强度比在没有这些不同要求的类似等级中可以达到的更高的蠕变强度。

1.3 The tubing sizes and thicknesses usually furnished to this specification are 1/8 in. [3.2 mm] in inside diameter to 5 in. [127 mm] in outside diameter and 0.015 to 0.500 in. [0.4 to 12.7 mm], inclusive, in minimum wall thickness or, if specified in the order, average wall thickness. Tubing having other diameters may be furnished, provided such tubes comply with all other requirements of this specification.

1.4 SI单元或英寸磅单元中所述的值应分别视为标准。在文本中，SI单元在括号中显示。每个系统中所述的值可能不是确切的等效物。因此，每个系统应独立使用另一个系统。结合两个系统的值可能会导致标准不合格。除非在订单中指定此规范的“ M”名称，否则应适用英寸磅的单元。
