check, pls.: http://www.bkotechnical.com/products-expansion-machine.html Hydro expansion is a method of expanding tube by means of pressurized water. The tube is filled with water and once filled the water is pressurized past the yield point of the tube therefore providing expansion. This method is used extensively in baseboard header assemblies and in coil production for bonding tubes to fin assemblies. |
