Rifled Seamless Tubes Available in Ready Stock!


Rifled tubes are used in boilers to provide highly energy efficient means of heat transfer. The presence of the internal rifling induces centrifugal forces in the mass flow thereby separating the water from the steam fraction and forcing the water towards the tube wall. As a result of this phenomenon and the increase in internal surface the following advantages accrue:
  • Improved heat transfer rate even at higher steam quality levels
  • Very good heat transfer even at low mass flux levels
  • Reduction in mean metal temperature of the tube wall
  • Ability to increase heat transfer rate by optimizing rifling geometry
