Are you planning to install new tubes in your firm…? Remember that you can’t expect every pipe and joint to be as ‘made for each other’…! Many times, you have to alter the tube diameter to some extent if you want to ensure a perfect joint of tube into the sheet. To serve this purpose, tube expansion systems have come into use. Prior to the advent of these techniques, mechanical rolling systems were in wide use. If you are still a fan of these vintage techniques, it’s time to get updated. Check out how the hydraulic expansion systems have successfully over taken the traditional methods employed for this purpose.
Precise expansion:
One of the biggest assets of hydraulic expansion systems is that, it can let you to apply precise pressure on to tube. All that you need to know is the amount of pressure required to be applied onto the tube. On the other hand, in mechanical rolling system, despite making use of torque rolling system, you can’t judge the degree of expansion accurately. Moreover, the torque controllers employed for this purpose, measure only the power consumed by the rollers. Other aspects like operator fatigue, lubrication, condition of mandrel and rolls are neglected.
Least distortion of the tube:
The tube will be subjected to high forces, which causes it to extrude axially, in mechanical rolling processes. In case of hydro expansion, though the tube stretches radially with ease, there is least effect on its axial expansion.
Unaltered tube surface:
Unlike in the primary methods, the hydraulic expansion systems don’t make use of work hardening techniques and so we achieve a smooth surface of the tubes. When the tubes are rolled into grooves, an axial expansion can take place. In the same context, if the tubes are hydro expanded; instead of axial expansion, bulging of the tube in radial direction takes place. These factors prove that hydraulic expansion system can result in a better tube to wall contact.
Corrosive resistant:
In majority of the firms, we can witness that, corrosion of the tubes is major concern. It is because; the tubes will be constantly subjected to working fluids. Rolled tubes have higher residual stresses inside them, increasing the chances of being corroded. This isn’t a problem when you prefer modern expansion systems. They ensure that the entire length of the tube has equal stress in it.
Faster and economical:
The time involved in this process is dependent on the material, thickness and other such factors of the tube. However, a sophisticated expansion system can let you do the work in hardly 2 to 5 seconds per tube. Moreover, man power can be reduced greatly in this case, which is in complete contrast to rolling procedures. In the rolling process, you have spent considerable time towards the setting up of rollers, mandrels and replace them if damaged.
Tube expansion is the perfect method of sealing the tube and the sheet. You can bring out the best of it, when you prefer to use the updated expansion systems.
A condenser is a major piece of equipment used mainly in HVAC industry. The condensers are used in both air conditioning systems as well as heat pumping systems. It is simply a heat exchanger, which helps in compression of various fluids into gases and decompression of gases into fluids. The coils present in the condenser are used for facilitation of heat exchanges between the fluids.
Condensers are available in a variety of sizes, capacities and designs. Mainly they are classified into three types according to the cooling method used by the condensers that are air cooled condensers, water cooled condensers and combined air and water cooled compressors.
Air cooled Condensers
An air cooled compressor uses a coil, which has ample amount of surface. This surface is normally cooled with the help of air, which is blown by a high capacity fan or air induced by natural draft. The air cooled condenser is mainly used in places where smaller amount of heat exchange is required such as domestic refrigerators. The air chilled condensers need to be kept away from dirt, lint or dust as it can decrease the efficiency of the condenser. The foreign materials can easily accumulate on the fins and tubes of the condenser and reduce the air flow.
Water cooled Condensers
The water cooled condenser use cold water to condense the fluid in the tube. The water cooled condensers are available in two types. In one type, the water is sprinkled from the outside of the tubes and the hot fluid is present inside the tubes. In the other type, the hot fluid is present in the shell of the condenser and the cold water travels through the tubes for heat exchange. The efficiency, performance and capacity of a water cooled boiler are higher as compared to the air cooled condensers.
Combined Air and Water Cooled Condensers
The combined condensers are those condensers that use both air and water for cooling. This condenser is provided with a coil that is cooled by sprinkling water on it. After the water has been sprinkled, cold air enters blown across the coil from bottom. As the water starts evaporating, it leaves a cooling effect on the fluid or refrigerant present in the coil. With a combined effect of water and air cooling, the refrigerant gas turns into a liquid. The water, which is not evaporated during the process, is then recycled with the help of a pump.
No matter which type of condenser you have, you must keep in mind that it is essential to take best care of your condenser to make sure it keep working for a long time. Without proper maintenance and care, it is very difficult to run a condenser on its best efficiency. In order to take best care of your condenser, first of all you must have a skilled maintenance team along with some of the tools such as tube cleaners, condenser tube expanders and so forth. With proper maintenance and care, you can surely obtain the best benefits of a condenser.
If you are planning to join the tubes of a condenser, then it’s the time for you to purchase the condenser tube expanders. A tight seal can be ensured by employing these techniques. The main job of these expanders is to join the tube edges with the metal similar to that of the tube. They are made of high quality alloy sheets and they are specially heat treated. This is a highly accurate and productive way of jointing condenser tubes.
Tube Expander Tools:
Expander Collars:
• Thrust bearing collar assembly is furnished up to 1-inch outer diameter tube sizes except 72 and 73 series 20-23 gauges.
• Deep recess collar this allows rolling from 1 to 3 inches.
• Close collar tubes are used to close the shell sides which allows the larger diameters to pass through them
Long reach expander:
Long-Reach Expanders expand tubes at points far back from the tube sheet, such as the point at which it passes through a baffle sheet.
• Tube Outer Diameter: 5/8 to 41/2-Inch, 8 to 22 Gauge
• Roll length: 1 1/2 or 2 1/4-Inch and Relieved
• Extended reach: 6, 12, 18, 24, 30, 36, or 60-Inch
Relieved rolls:

• For 1/2 to 2 1/2-Inch Outer Diameter Tubes.
Pipe sizing expander:
• These Pipe sizing expanders are used to increase the internal diameter of the tubes and pipes.
• They are also used for surface finishing of the internal surfaces of tubes so as to meet the tolerances mentioned as per the standards.
Captive Mandrel Expander:
• As the diameter of mandrel varies along its length so the tubes to be rolled when it is very near to the point of installation.
Linser flaring Expander :
• The Linser flaring expander is used for making tube connections by enlarging the diameter of the tube.
• After the diameter of the tube is varied it is easy to insert another tube.
Maintenance of Tube Expanders :
As the demand for tube expanders is high and the production rate is also high it is mandatory that the system should function with good efficiency. Continuous usage of the system leads to some errors. So there is a need for regular maintenance of the system. Some of them are as follows.
• The major problem encountered is, by the accumulation of the waste particles and sediments by fluids used in it. So as a part of maintenance, we should regularly clean to avoid the formation of sludges and scales.
• The devices which we use should be rinsed or cleaned so as to remove any grease, dust etc…
• The parts of expanders should be properly lubricated for the smooth functioning of the expanders.
• After the operation, they must be cooled properly and used for further usage.
Tube expanding with technology

Introduction:
The diameter of a particular portion of any tube can be made bigger with the help of tube expanders. There is a huge number of parts in this special tool, which make it unique. All these different parts are arranged together by a coil mechanism, which surrounds every end of this tool. To make these expanders special and tough, it is necessary to make them out of high quality material. The manufacturing process of these tools also has to be very advanced so that the material is crafted in the best form.
Expanding tubes becomes very necessary sometimes not only in industries, but in regular life activities, as well. But metal is not something, which can be messed around with bare hands. Something very structured and strong is needed to deal with this tough material, and thus, these expanders are needed. This expander makes the task of tube expansion easy, simple, and hassle free. The more the technology is advanced, less is the amount of time and efforts taken in the process. The plumbers keep these expanders in small sizes with them to tackle the tubing related issues with ease.
Types of expanders:
Most of the expanders of tubes come in different sizes, which range from minute to huge and are used for different size of the tubes. The expansion of these tubes becomes quite easy with these tools in hand. These can fit the little copper tubes of regular plumbing, which often need expanding to come over other tunes for fitting into a long tubing system or can be used in large industrial tubes.
These tools come in two different types which are used to expand into different portions of the tubes with ease. These two types are:
· Hydraulic expansion system
· Boil tube expansion system
These types of expanders are used in large scale, in different industries, to expand the metal tubes. These expanders come in various sizes, to fit the different sizes of tubes. These sizes make these equipments be used in industries, and regular plumbing systems. This increases the range of the use of these expanders. In the two expanders of tubes mentioned above, one uses hydraulic power to expand the tubes. These are developed with special technology, which make them quick and provide an effortless way of doing the work. This decreases the need of physical force, required by the tubes to expand. The hydraulic force can be controlled by the special technology, and with this accurately measured force, the tubes can be expanded in an appropriate fashion.
The other one is the used in the boilers. These are used to expand the tubes of boilers. They are also very special types of expanders, which expand the tubes of the boilers. The special needs of the general dimension tubes and drum can be fulfilled with the help of these special tools.
