Boiler Water Wall Tube Material

  • Composition of Boiler Tubes

    For any boiler retubing job, it is absolutely essential to use tubes that conform in every way to the tube requirements of the particular boiler. Boiler tubes are NOT identical. They differ in such important characteristics as composition of the metal, outside diameter, wall thickness, length, and curvature.
