Fixed Tube Sheet Heat Exchangers Manufacturer INDIA

A Fixed Tube Sheet heat exchanger is the most common type of heat exchanger in all Industries. Mostly used in higher-pressure and Higher Temperature applications.

 

Fixed Tube Sheet Heat Exchangers are the one that are very much used in process chemical industries and refinery services, as there is absolutely no chance for intermixing of fluids. This type of heat exchanger is employed where even slightest intermixing of fluids can not be tolerated. A fixed-tubesheet heat exchanger has straight tubes that are secured at bothends to tubesheets welded to the shell. The construction may have removable channelcovers , bonnet-type channel covers , or integral tubesheets. The principal advantage of the fixedtubesheet construction is its low cost because of its simple construction. In fact,the fixed tubesheet is the least expensive construction type, as long as no expansion jointis required.

 

 

Specifications :

  • The tube sheets at both ends of the fixed tube-sheet heat exchanger are connected and fixed with the shell by means of the welding method.
  • Fixed tube-sheet type heat exchanger features simple and compact structure, and low manufacturing cost for the same diameter of shell, the biggest number of caladria is available in tubular heat exchangers is widely applied in engineering.
  • In the event of a large differential temperature between the tubes and the shell, thetubesheets will be unable to absorb the differential stress, thereby making it necessary toincorporate an expansion joint.
  • This takes away the advantage of low cost to a significant extent.

Applications :

  • The Fixed tube-sheet heat exchanger are that shell pass cannot be cleaned with the mechanical method and the maintenance is difficult.
  • The Fixed tube -sheet heat exchanger is applicable to all services where the temperature difference between the shell and tube is small, the temperature difference is slightly great but the pressure of shell pass is not high with media in the shell pass not easy to scale.
  • The shell pass can be cleaned with chemical method after the scaling is formed.

Advantages :

  • The tubes can be cleaned mechanically after removal of thechannel cover or bonnet, and that leakage of the shellside fluid is minimized since thereare no flanged joints.
  • A disadvantage of this design is that since the bundle is fixed to the shell and cannot beremoved, the outsides of the tubes cannot be cleaned mechanically.
  • Its applicationis limited to clean services on the shellside.
  • Satisfactory chemical clean-ing program can be employed, fixed-tubesheet construction may be selected for foulingservices on the shellside.

Finned Tube Heat Exchangers

Finned Tube Heat Exchanger

Finned Tube Heat Exchangers is a type of heat exchanger design that uses plates and finned chambers to transfer heat between fluids. It is often categorized as a compact heat exchanger to emphasise its relatively high heat transfer surface area to volume ratio. The plate-fin heat exchanger is widely used in many industries, including the aerospace industry for its compact size and lightweight properties, as well as in cryogenics where its ability to facilitate heat transfer with small temperature differences is utilized.

A high degree of flexibility is present in plate-fin heat exchanger design as they can operate with any combination of gas, liquid, and two-phase fluids. Heat transfer between multiple process streams is also accommodated,

The main four type of fins are: plain, which refer to simple straight-finned triangular or rectangular designs; herringbone, where the fins are placed sideways to provide a zig-zag path; and serrated and perforated which refer to cuts and perforations in the fins to augment flow distribution and improve heat transfer.

ATU Cooler Finned Heat Exchanger

ATU Cooler Finned

Specifications :

  • Originally conceived by an Italian mechanic, Paolo Fruncillo.
  • A plate-fin heat exchanger is made of layers of corrugated sheets separated by flat metal plates, typically aluminium, to create a series of finned chambers.
  • Separate hot and cold fluid streams flow through alternating layers of the heat exchanger and are enclosed at the edges by side bars.
  • Heat is transferred from one stream through the fin interface to the separator plate and through the next set of fins into the adjacent fluid.
  • The fins also serve to increase the structural integrity of the heat exchanger and allow it to withstand high pressures while providing an extended surface area for heat transfer.

Applications :

  • The cost of Fin heat exchangers is generally higher than conventional heat exchangers due to a higher level of detail required during manufacture.
  • However, these costs can often be outweighed by the cost saving produced by the added heat transfer.
  • Fin heat exchangers are generally applied in industries where the fluids have little chances of fouling.
  • The delicate design as well as the thin channels in the fin heat exchanger make cleaning difficult or impossible.

Advantages :

  • High heat transfer efficiency especially in gas treatment
  • Larger heat transfer area
  • Approximately 5 times lighter in weight than that of shell and tube heat exchanger.
  • Able to withstand high pressure

Double Pipe Heat Exchanger

A double pipe heat exchanger, in its simplest form is just one pipe inside another larger pipe. One fluid flows through the inside pipe and the other flows through the annulus between the two pipes. The wall of the inner pipe is the heat transfer surface. The pipes are usually doubled back multiple times as shown in the diagram at the left, in order to make the overall unit more compact.

The term ‘hairpin heat exchanger’ is also used for a heat exchanger of the configuration in the diagram. A hairpin heat exchanger may have only one inside pipe, or it may have multiple inside tubes, but it will always have the doubling back feature shown.

 

Types of Double Pipe Heat Exchangers :-

1. Counter flow
2. Parallel Flow Heat Exchanger

 

1. Counter flow:-
The main advantage of a hairpin or double pipe heat exchanger is that it can be operated in a true counter flow pattern, To get More Efficiency, In the mean Time, it will give the highest overall heat transfer coefficient for the double pipe heat exchanger design.

 

2. Parallel Flow:-
Parallel Flow double pipe heat exchangers are focused to handle high pressures and temperatures applications. Also we can Achieve High Log mean Temperature using this.

 

3. Double Pipe Heat Exchanger Design:-

Determination of the heat transfer surface area needed for a double pipe heat exchanger design can be done using the basic heat exchanger equation: Q = UA ΔTlm, where:

Q is the rate of heat transfer between the two fluids in the heat exchanger in Btu/hr,

U is the overall heat transfer coefficient in BTU/hr-ft2-oF,Remove term:

A is the heat transfer surface area in ft2, and

ΔTlm is the log mean temperature difference in oF, calculated from the inlet and outlet temperatures of both fluids.

These parameters in the basic heat exchanger equation are discussed in ‘and they are used in an example in ‘ After determination of the required heat transfer surface area, the diameter and length of the inner pipe can be selected and then the diameter of the outer pipe. Finally, the length of the straight sections and the number of bends can be selected.

Specifications :

  • Some heat exchanger manufacturers advertise the availability of finned tubes in a hairpin or double pipe heat exchanger.
  • These would always be longitudinal fins, rather than the more common radial fins used in a crossflow finned tube heat exchanger.

Applications :

  • A primary advantage of a hairpin or double pipe heat exchanger is that it can be operated in a true counterflow pattern, which is the most efficient flow pattern.
  • It will give the highest overall heat transfer coefficient for the double pipe heat exchanger design.

Advantages :

  • Double pipe heat exchangers can handle high pressures and temperatures well.
  • When they are operating in true counterflow, they can operate with a temperature cross.
  • The cold side outlet temperature is higher than the hot side outlet temperature.

Copper Heat Exchanger

By | Heat Exchanger | No Comments

Copper Heat Exchangers Manufacturer INDIA

Copper heat exchangers are more efficient than shell and tube exchangers for low flow rates. Due to their simple construction they are low in price and easy to clean on the shell side. Their thermal efficiency approximates that of a true countercurrent flow type exchanger. Condenserors are used for condensation of vapours and cooling of liquids. Condensers are made by fusing number of parallel coils in a glass shell. Coils are made in different diameters using tubes of different bores.

 

Copper tubes are artificial to special requirements as to dimensional tolerances, finish and tempers for use in condensers and heat exchangers. These copper heat exchanger tubes are normally supplied in straight length in annealed & half hard temper. The copper tubes shaped by are metal industries not only have the stiff tolerances but also have the most dependable dimensions throughout the tube length. The tube surface is clean both inside and outside with no caustic stains. The copper tubes produced by are metal industries are suitable to transfer heat in a wide variety of operating conditions and to refuse to accept decay for the longest period of time possible under the harshest operating circumstances.

 

This is important because motors and motor-driven systems account for 43%-46% of all global electricity consumption and 69% of all electricity used by industry. Increasing the mass and cross section of copper in a coil increases the electrical energy efficiency of the motor. Copper motor rotors, a new technology designed for motor applications where energy savings are prime design objectives, are enabling general-purpose induction motors to meet and exceed National Electrical Manufacturers Association (NEMA) premium efficiency standards.

 

The average co-efficient of heat transfer in coil condenser is considered as :-
Condensation : 200 – 270 Kacl/m2, hr,oC apprx.
Cooling : 100 – 150 Kacl/m2, hr,oC apprx.

 

Specifications :

  • Copper is mostly used as a metal, but when a higher hardness is required it is combined with other elements to make an alloy 5% of total use such as brass and bronze.

Applications :

  • A small part of copper supply is used in production of compounds for nutritional supplements and fungicides in agriculture. Machining of copper is possible, although it is usually necessary to use an alloy for intricate parts to get good machinability characteristics.
  • The major applications of copper are in electrical wires (60%), roofing and plumbing (20%) and industrial machinery (15%).

Advantages :

  • The electrical properties of copper are exploited in copper wires and devices such as electromagnets.
  • Integrated circuits and printed circuit boards increasingly feature copper in place of aluminium because of its superior electrical conductivity (see Copper interconnect for main article); heat sinks and heat exchangers use copper as a result of its superior heat dissipation capacity to aluminium.
  • Vacuum tubes, cathode ray tubes, and the magnetrons in microwave ovens use copper, as do wave guides for microwave radiation.
  • Copper’s greater conductivity versus other metallic materials enhances the electrical energy efficiency of motors.
