Which domestic manufacturer produces the best expansion tubes? What’s the approximate price? Thank you
There are many manufacturers of expansion tubes in Wujiang, and the quality of their products is generally good. Here’s a link for you: http://www.hbzgq.com/product.asp. Huabo Expansion Tube Co., Ltd. in Wujiang is a decent option; it’s better to choose companies with a longer history
A mechanical tube expander, I guess around 4k. Thanks for the reminder below. This post was last edited by stevensun on 2009-3-17 07:20]
4K is the price of the tube expansion machine; the tube expander itself costs around 20 yuan.
A tube expander and an expander tool are not the same thing, right?
They are not the same thing. A tube expanding machine is a device used for expanding tubes, and it does not need to be replaced unless it gets damaged. A tube expander, on the other hand, is chosen based on the dimensions of the tubes and tube sheets; it is prone to damage. One tube expander can be used to expand around 100 tubes.
Then what I want to know is probably the tube expansion machine
There are many expansion tube machines made in Wujiang, but the control units of these machines tend to have problems; consider buying one and giving it a try
The control unit tends to break easily, but it’s also easy to repair when that happens. In fact, the control unit can be omitted; experienced technicians rely on their sense of touch instead. The price of expansion tubes is really high these days – I bought 20 expansion tubes with 25*2.5 lengthened rods yesterday, and each one cost 75! That’s insane! !
