ASTM A199/A199M Specification for Seamless Cold-Drawn Intermediate Alloy-Steel Heat-Exchanger tubes and Condenser Tubes.
ASTM A199 specification covers minimum-wall-thickness, seamless cold-drawn intermediate alloy steel tubes intended for use in heat exchangers, condensers, and similar heat transfer apparatus. These tubes are used for transporting fluids and gases at high temperatures and pressures.
The grades of steel covered by ASTM A199 are commonly used in industries such as petrochemical, power generation, and chemical processing, where high-temperature performance and resistance to corrosion are required. The choice of grade depends on several factors, including the specific application, environmental conditions, and required mechanical properties.
ASTM A199 tubes are produced using various manufacturing processes, including hot finished or cold-finished, and the tubes are then subjected to various tests such as flattening test, hydrostatic test or nondestructive electric test to ensure they meet the specified requirements.
Overall, ASTM A199 tubes are an important component of industrial heat transfer systems, providing a safe and efficient means for transporting fluids and gases at high temperatures and pressures.
ASTM A199/A199M is the standard specification for seamless cold-drawn intermediate alloy steel tubes, typically used in heat exchangers, condensers, and other heat transfer equipment. These tubes are designed for high-temperature services and are known for their strength, durability, and resistance to oxidation.
ASTM A199/A199M tubes provide exceptional performance in high-temperature heat transfer applications, such as heat exchangers, boilers, and condensers. Their seamless construction and cold-drawn manufacturing process ensure high strength, precision, and durability, making them a reliable choice for industrial applications requiring efficient heat transfer and corrosion resistance.
1.1 This specification covers several grades of minimum-wall-thickness, chromium-molybdenum and chromium-molybdenum-silicon, seamless, cold-drawn, intermediate alloy steel tubes for heat exchangers, condensers, and similar heat transfer apparatus.
1.2 The tubing sizes usually furnished to this specification are to 3 in. [3.2 to 76.2 mm] in outside diameter. Tubing having other dimensions may be furnished provided such tubes comply with all other requirements of this specification.
1.3 Mechanical property requirements do not apply to tubing smaller than in. [3.2 mm] in inside diameter or 0.015 in. [0.4 mm] in thickness.
1.4 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.
ASTM A199 specification covers several grades of ferritic steel, including Grade T5, Grade T9, Grade T11, Grade T22, and Grade T91.

Steel pipe are ubiquitous and can be found underground and within residential walls, laboratories, and commercial and industrial structures. Seamless steel pipe transport fluids including water, natural gas, waste and air. Three manufacturing methods exist to produce steel pipes.
Seamless steel pipes are produced using an extrusion mold. Welded steel pipes are produced by rolling a sheet of steel into a tube and welding the seam. Seamless steel pipes are less expensive. The third method is casting. Molten steel is poured into a casting mold.
Our steel pipes and tubes are the preferred choice for processes under the following conditions:
