Product Description

Boiler Alloy Steel Pipe

ASTM A213 Alloy Tubes

ASTM A213 Alloy Tubes are a series of seamless ferritic and austenitic alloy-steel tubes that are designed for use in high-temperature and corrosive environments.

ASTM A213 Alloy Tubes are commonly used in industries such as power generation, petrochemicals, pharmaceuticals, and chemical processing. They offer excellent resistance to oxidation and corrosion at high temperatures and pressures, making them ideal for use in severe environments.

The tubes undergo various tests, including hydrostatic testing, non-destructive testing, and tensile testing to ensure they meet the required specifications. The ASTM A213 standard covers a wide range of sizes and dimensions, allowing for versatility in applications.

Some key features and benefits of ASTM A213 Alloy Tubes include:

High-temperature resistance: The alloy steel used in these tubes offers excellent resistance to high temperatures and thermal shock.
Corrosion resistance: These tubes offer excellent resistance to corrosion and oxidation even in harsh environments.
Durability: The tubes are designed to withstand high pressure and temperature conditions, making them durable and reliable.
Versatility: ASTM A213 Alloy Tubes are widely available in various sizes, shapes, and dimensions enabling their usage in different applications.
Easy fabrication: These tubes can be fabricated easily, meaning that production costs are kept down.

In conclusion, ASTM A213 Alloy Tubes are a series of seamless ferritic and austenitic alloy-steel tubes that are designed for use in high-temperature and corrosive environments. They offer several key features and benefits such as high-temperature resistance, corrosion resistance, durability, versatility, and easy fabrication.

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 T5

Scope

(A) Maximum, unless range or minimum is indicated. Where ellipses (...) appear in this table, there is no requirement, and analysis for the element need not be determined or reported.

(B) It is permissible to order T2 and T12 with a sulfur content of 0.045 max. See 16.3.

(C) Alternatively, in lieu of this ratio minimum, the material shall have a minimum hardness of 275 HV in the hardened condition, defined as after austenitizing and cooling to room temperature but prior to tempering. Hardness testing shall be performed at mid-thickness of the product. Hardness test frequency shall be two samples of product per heat treatment lot and the hardness testing results shall be reported on the material test report.

(D) The terms Niobium (Nb) and Columbium (Cb) are alternate names for the same element.

(A) Maximum, unless a range or minimum is indicated. Where ellipses (...) appear in this table, there is no minimum and analysis for the element need not be determined or reported.

(B) The method of analysis for Nitrogen shall be a matter of agreement between the purchaser and the producer.

(D) For small diameter or thin walls, or both, where many drawing passes are required, a carbon maximum of 0.040% is necessary in Grades TP304L, TP304LN, TP316L, and TP316LN.

(E) Grade S30434 shall have (Ti + 1/2 Nb) of not less than 2 times and not more than 4 times the carbon content.

(F) Grade TP347LN shall have an Nb content of not less than 15 times the carbon content.

(G) Grade TP348 shall have an Nb + Ta content of not less than 10 times the carbon content and not more than 1.10%.

(H) Grade TP348H shall have an Nb + Ta content of not less than 8 times the carbon content and not more than 1.10%.

(I) Iron shall be determined arithmetically by difference of 100 minus the sum of the other specified elements.

(J) Al + Ti shall be 0.85 % min; 1.20 % max.

(K) Grade TP444 shall have Ni + Cu = 1.00 max.

(L) Grade TP444 shall have Ti + Nb content not less than 0.20 + 4(C+N) and not more than 0.80 %.

(M) N08020 shall have an Nb + Ta content of not less than 8 times the carbon content and not more than 1.00%.

(N) The terms Niobium (Nb) and Columbium (Cb) are alternate names for the same element.

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.

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.

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.
