Shell And Tube Heat Exchanger
Shell and tube is the most advanced technology available and is specifically engineered for particular applications. Heat exchangers are commonly used for the transfer of heat in industrial process applications. They are available in a variety of diameters and lengths. The U-tube heat exchangers are designed for a wide range of liquid to liquid and steam to liquid applications. The shell and tube heat exchanger is constructed using copper tubes and a carbon steel shell. It is manufactured using tide range of applications.
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 tube sheet allow for tube expansions and contractions, due to thermal fluctuations, without causing stresses on the joints. Welding tubes to the tube sheet 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 tube sheet 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. Applications Shell and tube heat exchangers 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.
It is the most common type of heat exchanger in oil refineries and other large chemical processes, and is suited for higher-pressure applications. As its name implies, this type of heat exchanger consists of a shell (a large pressure vessel) with a bundle of tubes inside it. One fluid runs through the tubes, and another fluid flows over the tubes (through the shell) to transfer heat between the two fluids. The set of tubes is called a tube bundle, and may be composed by several types of tubes: plain, longitudinally finned, and other types.
