Alloy Steel Heat Exchanger Tubes Manufacturer and Supplier
Amardeep Steel Centre LLP supplies alloy steel heat exchanger tubes to ASTM A213 for refinery and petrochemical process heat exchangers built to ASME Section VIII and TEMA rules. Our alloy steel heat exchanger tubes are available in T5, T9, T11, T22 and T91 grades with full mill test certification. For boiler pressure part duty under ASME Section I, see our Alloy Steel Boiler Tubes page.
What Are Alloy Steel Heat Exchanger Tubes?
Alloy steel heat exchanger tubes are Cr-Mo seamless tubes qualified for process heat exchanger and condenser service under ASME Section VIII and TEMA mechanical design rules, as distinct from the boiler code duty covered by our Alloy Steel Boiler Tubes page. The metallurgy is often the same ASTM A213 grade family, but the qualification code and mechanical design basis differ, so it is worth specifying which code your equipment is designed to rather than the grade alone.
Alloy Steel Heat Exchanger Tubes Grades
For the full grade by grade temperature rating and chemical composition, see the table on our Alloy Steel Boiler Tubes page. This page focuses on process duty selection rather than repeating that metallurgy in full.
| Grade (ASTM A213) | Code Basis | Typical Process Duty |
|---|---|---|
| T5 | ASME Section VIII / TEMA | Sulphidic corrosion service, fired heater exchangers |
| T9 | ASME Section VIII / TEMA | High temperature fired heater exchangers |
| T11 | ASME Section VIII / TEMA | Hydroprocessing unit exchangers, general refinery process duty |
| T22 | ASME Section VIII / TEMA | Higher temperature and pressure refinery and petrochemical exchangers |
| T91 | ASME Section VIII / TEMA | Severe service exchangers requiring the highest creep strength in this family |
Process Heat Exchanger Applications for Alloy Steel Heat Exchanger Tubes
- Refinery crude and vacuum unit exchangers
- Hydroprocessing unit exchangers in hydrogen service
- Petrochemical reactor feed and effluent exchangers
- Condensers in refinery and petrochemical service
Code and Standard Basis for Alloy Steel Heat Exchanger Tubes
Alloy steel heat exchanger tubes are designed under ASME Section VIII (pressure vessels) with TEMA mechanical design classes R, C or B governing the exchanger construction, in contrast to the ASME Section I boiler code basis used for alloy steel boiler tubes. Confirm which code your equipment falls under when placing an order, since the same grade can be supplied against either basis.
Testing and Certification for Alloy Steel Heat Exchanger Tubes
- Hydrostatic pressure test
- Ultrasonic and eddy current testing
- Hardness testing, particularly for T91 after post weld heat treatment
- Mill test certificate per EN 10204 3.1B

Alloy Steel Heat Exchanger Tubes FAQs
Q. What is the difference between alloy steel heat exchanger tubes and alloy steel boiler tubes?
The metallurgy is often the same ASTM A213 T-series grade, but the qualification code differs. Heat exchanger tubes are supplied for process duty under ASME Section VIII and TEMA mechanical design rules, while boiler tubes are qualified as boiler pressure parts under ASME Section I or IBR. Specify according to the code your equipment is designed to, not the grade alone.
Q. Which alloy steel grade is used for hydroprocessing unit heat exchangers?
T11 and T22 are commonly specified for hydroprocessing and general refinery process heat exchangers where hydrogen and sulphidic service require better creep and corrosion resistance than carbon steel, with T91 reserved for the most severe temperature and pressure combinations.
Q. Do you also supply the fabricated heat exchanger, not just the tubes?
Yes. Our Process Equipment division fabricates heat exchangers, pressure vessels, reactors, columns and tube bundles in addition to supplying the tube material, giving a single source path from raw tube to finished equipment.
