U Tube Heat Exchanger By yaang.com

U Tube is Designed for high temperature applications, especially steam condensing or hot oil system. Thïs model is selected when differential expansion make fixed tube sheet exchanger unsuitable and when preclude floating head type HPF selection.
– Design Pressure 12 bar(g)
– Design Temperature -20°C to +250°C
– Size range 80 thru 250dia, up to 6m long

  • Features

    • U-tube construction
    • Units designed for liquid to liquid and steam to liquid applications.
    • Available in 2 or 4 pass construction.
    • Removable tube bundles for convenience in cleaning and inspection.
    • Strong, durable construction with copper steel tubes and rugged cast-iron or steel head in standard units. (Optional materials are available).
    • Coil and baffle arrangements designed to maximize heat transfer performance.
    • Tubes expanded into stationary tubesheet allow for tube expansions and contractions, due to thermal fluctuations, without causing stresses on the joints. Welding tubes to the tubesheet is optional.
    • Advantages

      The advantage of the shell and tube design cannot be ignored. Each unit comes with:

      • connections that come in standardized sizes for easy assembly and feature additional thread and surface protection for clean installation
      • U-bend tubes expanded into a tubesheet which allow for tube expansions and contractions due to thermal fluctuations.
      • gaskets that are made of high quality compressed fibres which lends to reusability.
      • a standard cast-iron or steel head for heavy duty services (also available as a spare part).
      • saddle attaches which make for quick and easy mounting.
      • punched baffles with minimal clearances between tubes guaranteeing correct fluid flow and minimized bypass
      • a welded< shell protected with high quality paint for corrosion resistance.
      • copper steel tubes which allow for strong, durable performance over a wide range of applications. Unique tube bundle layout (chevron corrugated pattern) minimizes deposit buildup at the edges and optimises media flow for high velocity flow turbulence.

      Shell and tube heat exchanger are frequently selected for such applications as:

      • Process liquid or gas cooling
      • Process or refrigerant vapor or steam condensing
      • Process liquid, steam or refrigerant evaporation
      • Process heat removal and preheating of feed water
      • Thermal energy conservation efforts, heat recovery
      • Compressor, turbine and engine cooling, oil and jacket water
      • Hydraulic and lube oil cooling

      Shell and tube heat exchangers have been around for over 150 years. Their thermal technology and manufacturing methods are well defined and applied by the modern manufacturer. Tube surfaces range from standard to exotic metals with plain or enhanced surface characteristics. They can help provide the least costly mechanical design for the flows, liquids and temperatures involved.
