ASTM A213 tubing has been widely used in high temperature services especially for the boiler and superheater. Tube material could be in alloy steel and stainless steel, and manufactured in seamless of hot rolled or cold drawn. so this pipe usually used in very important places and the price is much higher than normal carbon pipes. Common grades are T9, T11, T12, T21, T22, T91 and stainless grades in TP304 or TP316.

ASTM A213 Alloy Tubes material could be in alloy steel and stainless steel, and manufactured in seamless of hot rolled or cold drawn. So this pipe usually used in very important places and the price is much higher than normal carbon pipes.

ASTM A213 Standard Scope:

ASTM A213 Standard Specification for Seamless Ferritic and Austenitic Alloy-Steel Boiler, Superheater, Heat-Exchanger Tubes.

1.1 This specification covers seamless ferritic and austenitic steel boiler, superheater, and heat-exchanger tubes, designated Grades T91, TP304, etc. These steels are listed in Tables 1 and 2.
1.2 Grades containing the letter, H, in their designation, have requirements different from those of similar grades not containing the letter, H. These different requirements provide higher creep-rupture strength than normally achievable in similar grades without these different requirements.
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 The values stated in either SI units or inch-pound units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. 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. The inch-pound units shall apply unless the “M” designation of this specification is specified in the order.

ASTM A213 VS ASTM A269

ASTM A213 pertains to seamless tubes, ASTM A269 can be both seamless and welded tubing.
ASTM A213 material contain Ferritic and Austenitic Alloy Steel, ASTM A269 only has Austenitic Stainless Steel.
Dimensional tolerances on outside diameter and wall thickness are not the same.
ASTM A213 used in heat exchanger system, ASTM A269 is for general service use, commonly instrumentation tubing.
ASTM A213 has ASME version SA213 for alternative, however, there are is no ASME SA269.
In practise, ASTM A213 and ASTM A269 can be dual certified standard.
