Products Overview
ASTM A106 seamless boiler tube is a carbon steel seamless pipe standard established by the American Society for Testing and Materials (ASTM) for high-temperature service. Manufactured through hot-rolled or cold-drawn seamless processes, this product is specifically designed for high-temperature and high-pressure applications up to 425°C. Its excellent oxidation resistance, creep resistance, and workability make it the preferred material in global industries such as petrochemical, power plant boilers, and high-pressure steam piping systems.
Products Dimensions
Wall Thickness: 0.055'' - 2'' (1.65 - 50mm)
Outer Diameter: 1/2'' - 30'' (21.3 - 762mm)
Key Application Industries
| Industry | Specific Application |
|---|---|
| Petrochemical | Process lines in FCC units, reformers, crude units; high-temperature oil & gas transport |
| Power Generation | Main steam headers, reheat steam lines, feedwater heater tubes |
| Boiler Manufacturing | External boiler headers, downcomers, superheater connecting pipes, economizer tubes |
| Engineering Machinery | High-temperature hydraulic lines, heat exchanger tube bundles, pressure vessel nozzles |
| Marine Industry | Marine boiler systems, steam tracing lines |
Key Advantages
| No. | Advantage Description |
|---|---|
| 1 | 100% Seamless Construction – eliminates weld-related defects, offering superior fatigue and corrosion resistance. |
| 2 | Strict Heat Treatment Process – normalized after hot rolling or stress-relieved after cold drawing to stabilize microstructure. |
| 3 | Full Size Coverage – supports small-batch customization and non-standard wall thicknesses. |
| 4 | 100% NDT Tested – every tube is examined by eddy current or ultrasonic method. |
| 5 | Excellent Weldability – tight carbon equivalent (CE) control; preheating not required for Grade B. |
| 6 | Full International Certification – EN 10204 Type 3.1 material certificate and third-party inspection (BV, SGS, TÜV) available. |
