A boiler tube is a seamless or welded steel tube designed for high-temperature and high-pressure service in boilers, superheaters, economizers, heat exchangers, and other heat-transfer equipment.
Manufactured from carbon steel, alloy steel, or stainless steel, boiler tubes are supplied in accordance with ASTM, ASME, EN, and GB standards for demanding industrial applications.
The table below shows our standard manufacturing range for seamless boiler tubes.
| Item | Specification |
|---|---|

| Outside Diameter (OD) | 10.2–139.7 mm (Hot rolled: from 26.9 mm) |
| Wall Thickness (WT) | 0.5–16.0 mm (Hot rolled: from 2.6 mm) |
| Material | Carbon Steel / Alloy Steel / Stainless Steel |
| Standards | ASTM A210, ASTM A213, GB/T 3087, GB/T 5310, EN 10216 Series |
| Delivery Condition | Hot Rolled / Cold Drawn |
| Test | According to applicable standards |

Boiler tube material is selected according to the required operating temperature, pressure, corrosion resistance, and service environment. Carbon steel is commonly used for low- and medium-temperature service, while alloy steel and stainless steel are preferred for high-temperature and corrosion-resistant applications.
| Material | Common Grade | Recommended Service Temperature | Typical Application |
|---|---|---|---|
| Carbon Steel | ASTM A192 | Low to Medium | Carbon steel grades such as ASTM A192 and ASTM A210 are commonly used for low- and medium-pressure boiler service. |
| Carbon Steel | ASTM A210 Gr.A / Gr.C | Medium | Boilers and superheaters. |
| Alloy Steel | ASTM A213 T11 | ≤ 550°C | Superheaters, steam pipelines. |
| Alloy Steel | ASTM A213 T22 | ≤ 600°C | High-pressure boilers, headers. |
| Alloy Steel | ASTM A213 T91 | ≤ 625°C | Supercritical boiler systems. |
| Stainless Steel | ASTM A213 TP347H | ≤ 650°C | Superheaters and reheaters. |
| Stainless Steel | Super304H | Up to 700°C | Ultra-supercritical boilers. |
| Stainless Steel | HR3C | Up to 700°C | High-temperature superheaters. |
Carbon steel boiler tubes are widely used for low- and medium-temperature applications because of their cost efficiency. Alloy steel grades provide improved creep strength for high-pressure service, while stainless steel grades are preferred where high-temperature oxidation and corrosion resistance are required.
Boiler tubes are manufactured according to different international standards depending on the project specification, operating conditions, and regional requirements.
| Standard | Common Grades | Primary Use |
|---|---|---|
| ASTM | A192, A210, A213 | Material and manufacturing specifications for boiler and heat exchanger tubes. |
| ASME | SA192, SA210, SA213 | Boiler and pressure vessel specifications widely used in power generation projects. |
| EN | EN 10216 Series | European standards for seamless pressure tubes. |
| GB | GB/T 3087, GB/T 5310 | Chinese national standards for boiler tubes and pressure applications. |
Boiler tubes are supplied with inspection and documentation according to the applicable product standard and customer requirements. Inspection scope and documentation can be provided according to project specifications and contract requirements.
