Boiler Bank Tubes
Boiler Bank Tubes are high-strength, heat-resistant tubes used in the boiler bank section of steam boilers. These tubes connect the steam drum and mud drum, enabling efficient water circulation and steam generation. Manufactured using seamless or welded processes, Boiler Bank Tubes are designed to withstand high temperature, internal pressure, and thermal cycling. These tubes are widely used in power plants, sugar mills, chemicals, refineries, and large industrial boilers. Their uniform structure, smooth internal surface, and high mechanical strength make Boiler Bank Tubes essential for reliable boiler performance, steam generation efficiency, and long operational life.

Size & Thickness Range
| diameter | thickness | use |
|---|---|---|
| 1” – 2” OD | 2.0mm – 6.0mm | Small industrial boilers, heat transfer lines |
| 2” – 3” OD | 3.0mm – 8.0mm | Boiler bank tubes, steam circulation |
| 3” – 4” OD | 4.0mm – 10.0mm | High-pressure boiler bank systems, power plant boilers |
Manufacturing Process
Boiler Bank Tubes are manufactured using seamless or ERW processes designed for high-temperature and high-pressure boiler applications. The process starts with steel billets (for seamless) or steel strips (for ERW), which are heated and formed into tubes. Tubes undergo heat treatment such as normalizing or stress relieving to ensure thermal stability and mechanical strength. Hydrostatic pressure testing and Non-Destructive Testing (NDT) such as ultrasonic and eddy current tests are performed to ensure reliability. Dimensional checks, straightening, and finishing are performed to meet IS 1914, BS 3059, ASTM A192, and ASTM A210 specifications. We maintain a wide inventory of Boiler Bank Tubes suitable for power plants, sugar mills, chemical boilers, and industrial steam systems.
