Shell and Tube Heat Exchanger Manufacturer & Supplier

About Shell And Tube Heat Exchanger

Pragya Associates is a prominent shell and tube heat exchanger manufacturer and supplier offering heat exchangers that efficiently exchange heat between two fluids in engines, transmissions, and hydraulic power systems in different Industries. Our shell and tube heat exchangers are used in many comforts and industry applications for heating and cooling fluids. They consist of a shell with traditional plain tubes or enhanced surface tubes for high thermal performance. The fluids can be liquids or gases, one of which flows inside the tubes while the other flows outside the tubes within the shell. There are single-phase or two-phase heat exchangers, and the latter is used to either boil or condense fluids. Shell & Tube Heat Exchangers are most commonly used in almost all industries like- Refineries, Chemical plants, Fertilizer plants, Genset units, Oil & Gas, and Shipping. The typical use of the Alfa Laval Heat Exchanger is to cool or heat the fluids or gases. As the leading and reliable heat exchanger manufacturer, we have been providing high-quality products to our customers for years.

Shell and tube heat exchangers are widely used throughout the engineering world and are among the two most common types of heat exchangers; The other common type is the plate heat exchanger.


Shell and tube heat exchangers have a simple structure, robust properties and relatively low acquisition and maintenance costs. They also have a very high rate of heat transfer, although they take up more space. than a plate heat exchanger heat exchanger with a similar heat exchange capacity.

Types of shell and tube heat exchangers

U-tube heat exchanger:

U-tube heat exchanger is a kind of shell-and-tube heat exchanger, it belongs to petroleum and chemical plants. This type of heat exchanger is named after a U-shaped tube. U-tube consists of some main components such as box tube, shell and tube buddle. Also, after the U-tube heat exchanger hydraulic test, it is easy to dry.

Fixed tube sheet exchanger

A fixed tube sheet heat exchanger is the most common type of heat exchanger in all industries. Fixed tube sheet heat exchangers for higher pressure and higher temperature applications. Fixed tube sheet heat exchangers are often used in the chemical process industry and in refineries, since there is absolutely no possibility of liquids mixing, this type of heat exchanger is used where it cannot be tolerated or where even the slightest mixing of liquids has straight pipes which are fastened on both sides to tube sheets welded to the jacket. have removable duct covers, hood-like duct covers for the tube sheets. The main advantage of the fixed tube sheet heat exchanger construction is its low cost due to its simple construction.

Floating head exchanger

A floating head heat exchanger is one of the most commonly used heat exchangers. As the name suggests, one end of the tube sheet is attached to the shell, while the other end can “float” freely in the housing.

Both the shell and the tube bundle are free of expansion, so that they do not cause any thermal stresses between the shell and the tube bundle when there are large temperature differences between the two media, because floating head heat exchangers are often used for services where the temperature between the shell and the tube bundle is high, or for dirty services like oil refineries. With high reliability and great adaptability, the float head heat exchanger has accumulated a wealth of experience over the course of many years of use and continuously advanced its development Shell and tube heat exchanger in which the tube plate assembly is free and can move freely within the housing or housing cover. The tube bundle and the tube bundle are tall, which causes expansion problems. Floating head heat exchangers are the best heat exchangers in terms of efficiency and maintenance, but they are inherently expensive.With high reliability and great adaptability, variable area heat exchangers have accumulated a wealth of experience over many years of use and continuously advanced their development. Among all types of heat exchangers, the floating head heat exchanger has so far still taken the top position.

This type of heats exchanger can be applied as a solution:
  • High thermal efficiency
  • Corrosive air currents
  • High temperature
  • Cooling applications
  • Shell and Tube Heat Exchanger Applications

    Shell and tube heat exchangers are used in different industries to transfer heat efficiently. Here are some common applications:

    HVAC Systems

    They help cool or heat buildings by exchanging heat between fluids like water or refrigerant in tubes and air in the surroundings.

    Power Generation

    They are crucial in power plants to convert the steam back into the water for reuse by transferring heat from the steam to cooling water.

    Oil and Gas Industry

    They cool down crude oil, help with distillation, and process gases in oil refineries. They maintain the right temperature for fluids in different processes.

    Chemical Processing

    They are used in chemical plants for reactions, separation processes, and cooling products. They can handle corrosive chemicals.

    Food and Beverage Industry

    They pasteurize, sterilize, and cool down food and drinks. They ensure products are safe and of good quality.

    Pharmaceuticals

    Shell and Tube Heat Exchangers are also used in making medicines, recovering solvents, and purifying chemicals. They meet strict temperature requirements.

    Refrigeration Systems

    They help cool or heat places by transferring heat between refrigerants and the environment.

    Waste Heat Recovery

    They capture and transfer excess heat from waste gases or liquids to save energy and make processes more efficient.
