Tube expanders are rolling-type tube expanding tools used for fastening and forming tubes into tube sheets in heat exchanger manufacturing processes such as boilers and condensers. In general, tube expander help to reduce tube walls by compressing the outside diameter of the tube to a fixed container. This particular concept is useful when dealing with case assemblies. They will be based on thrust colour, which will help people get the benefits associated with proper sealing.
Construction of Tube Expander
Roller:
Rollers apply rolling pressure to facilitate plastic deformation of the inside of the tube. It has a tapered shape and is designed so that the inside of the expanded tube always has a spherical shape. This avoids severe stress after tube expansion.
Mandrel:
A mandrel is used to rotate the roller through contact friction. It has a slender shape like a roller. The roller and mandrel need to withstand pressure and abrasion. Therefore, they use special steel to undergo proper heat treatment and finish with precise grinding.
Frame:
The frame maintains the position of the rollers periodically and prevents falling. It also provides the feed angle into the grooves the rollers insert. Therefore, it is configured by rotating the mandrel clockwise. This, in turn, creates a screw-feeding mechanism like a self-propelled mechanism, which results in automatic tube expansion.
Ball Bearing Neck:
A ball bearing is attached to the tube expander, which attaches the bearing sleeve, reducing thrust while expanding the tube. They will prevent damage to the tube ends and sheets by adjusting the installation position forward or backward. This makes achieving an adequate length and reach for the rollers possible.
Benefits of Tube Expander Tool
Very Suitable Length:
One of the main advantages of using a tube expander is that it is based on a very suitable length based on the technical dimensions of the internal diameter. The most popular option, in this case, is beneficial in providing people with an understanding of heat exchangers and condensers to avoid any problems.
Recommended In The Case Of Thin Walls:
Using a tube expander is also a good idea and is recommended by experts for fragile walls made of stainless steel, titanium and other exotic materials. The best part in this case is that it will also provide good support to people in the case of thick tube sheets.
More Centralized:
One of the essential reasons to rely on tube extenders is that they will provide mutual benefits to people. It also helps in dealing with expansion very quickly compared to conventional options. Due to this specific factor, People can enjoy using things in the best possible way.
Improving Feed Angle:
One of the main reasons to use the tube expander machine is that it comes with an increased feed angle. This makes it one of the fastest operating tools available in the industry. Moreover, it is ideal for higher production environments throughout the process. The attractive benefits of this product make it very popular, and the best part is that everything is optional, as in the case of a quad drive system.
