Understanding The Working Mechanism of Tube Expansion

Tube expanders are instruments that are used in the manufacture of the heat exchangers including boilers and condensers for the fastening and moulding of tube tubes to roll sheets.

Roller

A rolling pressure is exerted on the roller for the deformation of the plastic within the container. It is tapered and is designed to often attain a spherical structure on the inside of extended tubes.

The tip of the electric tube expansion system also comes with a smooth R-shaped cavity. This helps prevent an intensive tension accompanying extension of the tube and prevents the development of sharp edges within the tubes.

Mandrel

The mandrel is used for touch friction spinning the roller. It is conical like the roller. It has a conical form. The roller and mandrel must both be pressurised and resistant to abrasion. The special steel is then used and is suitable for heat treatment as well as finishing by using precision grind.

Frame

The frame constantly retains the position of the rollers and avoids dropping. The flow angle to the groove at which the roller is inserted is also given. A structure is then obtained that rotates the mandrel in the clockwise direction. In exchange, pneumatic tube expansion drive produces a self-propelling automatically expansion system like a screw-feed.

Collar bearing

The Tube Expander has a bearing collar. There was a mistake (Except BK-type) Attaching a conveyor collar results in a reduction in the thrust as the tube is extended and losses to the end and the tube layer are avoided.

In addition, it is possible to obtain an appropriate longitude and hit duration for the roller by changing the installation position forward or backwards.

The electric tube is a storehouse of surprises. This tube though looks like an illuminating device however, the usage of the same is very difficult. The dynamics with which it made is very unique. This tube is made up of glass and inside this tube has a gas called nitrogen stored in it. This device works with the help of inert gases which are stored therein. The inert gases create a vacuum. This vacuum operates the filament and its filament is able to retain its shape in the presence of this gas.

Even when the gas is not available in the right quantity, the filament can adjust itself accordingly.  However when the gas gets reduced by a substantial amount then there is a possibility of the expansion of filament. If this filament gets expanded they there are chances of the explosion of the tube. The expansion of the tube is even caused by other allied factors. These factors can include an increase in the atmospheric pressure and at the same time, include other factors as well. The filament gets exposed even when the content of carbon dioxide emissions increase in the surroundings.

There are times when there might be a situation wherein the filament might not expand but the heat produced by the filament by the combustion increases to such an extent that the heat gets converted to some kind of pressure inside the tube. This pressure is at times created inside the tube and it is the tube and not the filament that expands and breaks. This phenomenon is very dangerous and at times can cause serious incidents. Therefore it is advisable that every tube should be switched off for at least some time so that overheating doesn’t take place and these accidents are prevented from happening.

Tube Expanders For Expanding the Internal Diameter of Tubes

To offer heat and cooling effect for changing one state to another, condensers, boilers, heat exchangers, and other special machines are employed. To give power to the machinery, they are utilized in different factories, industries, and manufacturing units also.

Tube Expansion: Basic Principles And Methods

Tube Expanding is the process by which the tube wall is reduced by compressing the outer diameter of the tube against a fixed container. It can be done easily by keeping tubes into tube sheets. There is specified data to determine the correct tube wall reduction. Tubes are seated tightly whose expansion is somehow impossible manually as it is expanded so as to manufacture heat exchangers for high-pressure steam generators, Food and Pharmaceutical processing systems, Boilers for conventional power generation and Condensers. So, it is very important to decide the best method and tube expansion system for tube expanding. There are several factors for the determination of dimensions, thickness and application of force must be taken as prior so as to expand the tube in a better way.

There is a requirement of tube expansion tools for proper expansion and durability of the tubes. There are various types of tube expansion systems. Some commonly used tube expansion systems are:

• Hydraulic Tube expansion system
• Electric Tube expansion system
• Sugar Mill Tube expansion system
• Torque Controlled Tube expansion system
• Radiator Tube expansion system and others.

There are various accessories like Rolling drives, Torque controllers, Voltage stabilizer, Suspension system etc. are used. By the expansion of the tube inside the tube sheet, swaging of the tube gives the clear data about the space between the two components is always forced closed.

Tube Expansion Methods

1. Hydraulic Expansion: It is the latest expansion method, also known as hydro-swaging. It is the more effective method than roller expansion for high-pressure steam generators. In this method, expansion pressures are applied uniformly, tube after tube, which ensures the consistent joints throughout the tube sheet.
2. Explosive Expansion: It is done when tubes sheets are sealed by welding. It is used for variation in the thickness of tubes. It is the more expensive way of tube expansion than hydraulic expansion.
3. Mechanical Rolling: It is the process in which one roller expands tubes into grooved holes which lead the tube metal extrudes into the grooves. However, this process may cause tube-end fatigue, depending upon the frequency and amplitude of the stresses applied by the rollers.

Major Causes of Tube Leaks

Common causes of tube rolling leakage are under-rolling, over-rolling, improper preparation of tube sheets and differential thermal expansion. Improper expansion can lead to serious difficulties for the manufacturers and repair servicemen. It is important to set the torque of rolling devices. All the dimension should be kept in mind during tube expansion.

The wall dimension can be reduced and increased anytime with proper care. There are specified factors of specific materials like brass, copper, stainless steel, titanium, etc. It is the fact that harder the material, the less wall reduction is required to obtain a tube joint. It is very important to check the quality of the equipment required for tube expansion. There are many manufacturers who produce machines for tube expansion with technological advancements and machinery introduction. Thus, you can select any of them according to your needs.

Understanding the different components of a boiler

A boiler is magnificent and very important equipment for the facility where it is installed. It is important to know how to operate the boiler properly and keep its health optimum so that it could serve you for a long time. There are many components that you need to have knowledge of, so that you could keep them healthy and working. Let us see the different components of a boiler installed on it.

Boiler feed pumps

A boiler feed pump is responsible for feeding water to the boiler tubes or shells. It is necessary to maintain a certain level of water in the boiler to be safe. If the level of water falls below the safe level, it may cause the boiler shell or tubes to crack. For that reason, you must have a boiler feed pump in spare so that it could replace the feed pump installed on the boiler in case of any defect or break down.

Gauges and meters

There are different gauges installed on the boiler such as water level indicator, pressure gauge and thermometer, which are necessary to determine the values of the different working factors at a given time. In the absence of these gauges, it would be very difficult to keep these working factors under safe level. It is important to keep the gauges installed on a boiler working so that the operator of the boiler could keep the boiler working under safe limits.

Boiler tubes

Boiler tubes are responsible for the transfer of the fluids and heat throughout the boiler. If the tubes of a boiler are not healthy and perfect, the boiler cannot deliver its best performance. It is important to keep the boiler tubes healthy and perfectly working for best efficiency of the equipment. The tubes must be cleaned regularly with help of tube cleaners to keep the tubes free from any types of sludge and dirt. If a tube is defected, it needs to be flared so that a new tube could be inserted in it to restore its working. An electric tube expansion system would be best for doing that as it can expand the diameter of the tube without much problem and without causing any damage to the tube.

Exhaust fan

The exhaust fan of a boiler is the component, which sucks the hot air and smoke out of the boiler. Boiler cannot work at all if the exhaust fan of the boiler is not working properly. It is necessary to check the exhaust fan regularly to make sure that it is working in an efficient manner.

The chimney

It is the part of the boiler, which keeps the surrounding area of the boiler smoke free as it takes the smoke far from the working area of the boiler. You must make sure that the chimney of the boiler is high enough to take the smoke to the environment. Also, the chimney must have carbon filters so that the pollution done by the boiler could be minimized.
