Boiler tubes

is tubes used for boiler systems, like boilers for civil use in life, general industrial boilers, locomotive boilers and thermal power boiler.

Sunny steel are instrumental in offering our clients with a wide range of Boiler Tubes that is used in varied industrial applications. These Boiler Tubes are known for their resistance to corrosion and tolerance for withstanding temperature variations. We also undertake customization of these tubes to meet the specific requirements of our clients.

Boiler Tubes are metal tubes located inside of boilers that heat water in order to produce steam. There are two major types of tube boilers: water-tube boilers and fire-tube boilers.

Application: For high, middle, low pressure boiler and pressure purpose

3 thoughts on “Boiler tubes”

  1. Boiler Tubes are metal tubes located inside of boilers that heat water in order to produce steam. There are two major types of tube boilers: water-tube boilers and fire-tube boilers. In water-tube boilers, water circulates inside the tubes and is heated externally by hot gases generated by the furnace.

  2. Length [m] for sizes [mm]

    5 – 6 OD < 60.3 5 – 6 or 10 – 14 OD => 60.3 and WT < 7.1 5 – 6 OD => 60.3 and WT => 7.1

  3. We also offer quick turnaround for several seamless grades so if you have an outage and need replacement tubing quick, we are your solution provider.
