Machine Overview
This equipment is a stainless steel tube expander machine specially design for medical heat exchanger. It uses the hydraulic station driven by servo motor as the main power source. Compared with the traditional hydraulic station, it has many advantages, such as more power saving, no noise, etc And its torque output is more powerful. It can easily expand the stainless steel tube with a wall thickness of 1.5mm.
The machine adopts PLC for intelligent control, and the user can freely control the expansion speed of the machine. The speed control range is 0.5-10 meters. This production speed can meet the production requirements of 100% heat exchangers in the market. Not only that, the user can also set the required tube length through the touch screen, and the size error range is 0.01 mm.
A high-pressure filtration device is installed on the hydraulic station, which can effectively filter impurities in the hydraulic system. This filtration device adopts a flexible design, and users can replace the internal filter core to keep the hydraulic oil clean for a long time, ensuring the service life of the hydraulic station.
Advantages of stainless steel tube expander machine
The manual expansion tool is already include
The manual expansion tool of this machine is driven by hydraulic pressure and has been connected to the hydraulic station of the machine. There will be no additional cost of using this tool during the production process.
Silent production mode
Due to the servo motor drive used in the hydraulic station of this expansion machine, it can adapt to a running speed of 50-2000 revolutions per minute, avoiding the constant speed operation of traditional motors and effectively reducing the noise of the machine during operation. Compared with traditional hydraulic stations, its noise can be controlled within 0-35 decibels, reducing energy consumption by 50%.
Powerful power output
This stainless steel tube expander machine is specially design for tube with a wall thickness of more than 1mm. We have matched this machine with a powerful power reserve. It can easily expand tube made of stainless steel, titanium alloy and other metals, and adapt to various tube ‘diameter dimensions without cumbersome die changing processes.
Seamless adaptation to multiple heat exchangers
The standard length of the expansion rod of this machine is 5 meters. We can increase it to 15 meters according to the user’s requirements to meet the user’s special requirements. Not only that, its tube pitch adopts flexible design, and the user can change a simple tool to produce heat exchangers with different tube pitch.

Precautions for installation of stainless steel tube expander machine
The first time you use this expanding machine, you need to set up the servo motor driver, otherwise the touch screen will display an alarm. We provide detailed text instructions and videos, and you can follow the steps in the instructions to set it up. The entire process is very simple.
Because ship transportation does not allow oil inside the machine, when you receive this stainless steel tube expander machine, you need to add 32-38 # mechanical hydraulic oil to the hydraulic station, which requires approximately 35 liters.
You need to prepare a table for the heat exchanger, place it horizontally on this table, and then reserve sufficient space for the expansion rod of the machine, as you can see in the video above.
The touch screen has multiple built-in working modes, and users can switch between them at once. However, it should be noted that each time you switch, you need to set the original position of the metal ball, and the machine will record this position and automatically stop at the position.
In order to reduce the friction of the metal ball, some lubricating oil should be added before the tube is expanding, which can effectively reduce the friction coefficient of the metal ball and extend the service life of the machine.
The control system of this SS tube expansion machine is design to prevent errors, but we strongly recommend that users completely shut down the machine when replacing the mold to avoid any mistakes that may cause irreversible damage.
Final summary
This is a heat exchanger manufacturing machine used in the medical industry. Its role is to expand stainless steel tube and closely combine fin, so that the liquid flows in the tube of the heat exchanger can fully transfer heat to fin, and then conduct efficient heat exchange. This expander uses the most advanced servo hydraulic station as the main power to output powerful power to meet the expansion of high-strength tube such as stainless steel and titanium alloy.
If you are looking for a device to meet your heat exchanger production and improve work efficiency, this stainless steel tube expander machine is very suitable for you. It not only can easily expand metal tube with a wall thickness of about 1mm, but also can work with low energy consumption and quiet production If you need to know more details about this machine, you can contact our engineers to obtain it.
