    Twisted Tubes

     

    The heat exchangers used Henglong Twisted Tubes have 40% higher heat transfer coefficient for the same pressure drop as conventional shell & tube heat exchangers. Complex swirl flow on the shellside induces the maximum turbulence to improve heat transfer. Powerful tubeside turbulence is achieved even at high viscosities and/or low velocities. Uniform flow distribution gives more effective length and surface area than shell & tube exchangers.

     

    Twisted Tube heat exchangers are self-supporting so baffles are not required. There is less vibration as tubes are supported at multiple contact points and the reduction in turbulence means no dead spots with the hope fouling will be reduced.

     

    Comparing with conventional heat exchanger tubes, our Twisted Tubes have following features:

    • Higher heat transfer efficiency

    • Smaller exchangers and fewer shells

    • Less flow vibration

    • Reduced fouling

    • Increased capacity

    • Lower installed costs

    • Lower pressure drop

    • Extended working time
