How to use a tube expander? What should I do if the copper tubes of my heat exchanger corrode and start leaking in the middle? Can a tube expander be used?
I don’t quite understand what the original poster means. Since the heat exchange tube is leaking, it should be removed and replaced, or the tube should simply be sealed off. What does that have to do with a tube expander?
The tube expansion area must be cleaned thoroughly to ensure the quality of the tube expansion.
I’m planning to replace the copper pipes now, but since I’ve never used a pipe expander before, I need to buy one. Another question is how to determine the specifications of the tube expander? My tube is 16*0.55*4200.
A tube expander can be connected to multiple tube ends; all you need to do is purchase tube ends that match the size of your heat exchange tubes!
Copper pipes can be expanded; expander tools are not expensive and are available on the market. Expander specifications: Outer diameter of heat exchange tube × wall thickness × expansion length – Length to which the heat exchange tube can extend without expansion
Why use a tube expander? On the one hand, it prevents the weld at the tube end from coming into contact with the medium in the shell side, thus avoiding gaps when viewed from above; on the other hand, it enhances the strength of the tube end
For a damaged pipe, it’s simply enough to block it off; in most cases, it’s not easy to remove it
