Product Profile of Multi-Rifled Seamless Cold Drawn Boiler Tube
ISMT Limited supplies Multi-Rifled Seamless Cold Drawn Boiler Tube. ISMT Limited manufactures a wide range of precision seamless tubes and alloy steel tubular products for the Bearing, Automotive, Mining, General Engineering and Energy sectors. The Multi-Rifled Seamless Cold Drawn Boiler Tube is used in heat exchangers and boilers to provide highly energy efficient means of heat transfer. The Multi-Rifled Seamless Cold Drawn Boiler Tube comes with internal rifling that induces centrifugal forces in the mass flow thereby separating the water from the steam fraction and forcing the water towards the tube wall.
Key Features of Multi-Rifled Seamless Cold Drawn Boiler Tube
- Improved heat transfer rate even at higher steam quality levels
- 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
