What Are Boiler Tubes?
These Tubes are special steel pipes used to carry hot fluids or gases inside a boiler system. They help transfer heat and play a critical role in generating steam or hot water. These tubes need to withstand extreme pressure and temperature conditions, making their quality and material specifications highly important.

Features of ASC LLP Boiler Tubes
- High-temperature resistance
- Excellent corrosion resistance
- High tensile strength
- Superior durability
- Perfect dimensional accuracy
- Easy to install and maintain
Types of Boilers
1. Water-Tube Boilertubes: In Water-Tube Boilers, water flows inside the tubes, and hot gases pass over the outside. These tubes are typically used in high-pressure boilers. Water-tube boilertubes are preferred in power plants, industrial boilers, and marine applications.
2. Fire-Tube BoilerTubes: In Fire-Tube Boilers, hot gases pass through the tubes, and water surrounds them. These are used in low to medium-pressure applications such as heating systems, small industrial plants, and building complexes.
3. Seamless BoilerTubes: Seamless boilertubes are made without any welds. They are stronger and more reliable, especially for high-pressure and high-temperature applications. At ASC LLP, we manufacture and supply top-grade seamless boilers that comply with international standards.
