Five slot straight pipe expander

Five slot straight pipe expander

The mechanical five-slot straight tube expander can only be used if the inner diameter of the tube is greater than Φ17. Compared with the three-bead expander, due to the two more beads, the friction resistance is reduced, the expansion of the tube is obviously labor-saving, and the inner diameter of the tube after expansion is rounded and the expansion of the bead is not easy to break. It is especially suitable for the expansion of the tube wall below 0.7mm and the expansion of the thick wall tube with large pipe diameter.

Please confirm the following when purchasing:

1, Pipe size outside diameter D× wall thickness L

2, Pipe material

3, tube plate thickness T1, T2

4, pipe plate quality

The mechanical five-slot straight tube expander is widely used in the manufacture and maintenance of condensers, coolers, heat exchangers, boilers and other pressure vessels in refrigeration, petrochemical, power, shipbuilding, metallurgy and other industries. It can expand the pipes of copper, aluminum, titanium, iron, stainless steel and other materials.

Use and maintenance of tube expander:

The main parts of the tube expander have been heat treated, with high hardness, and must be placed horizontally with the expanded pipe when used, and the applied force in the expansion pipe work is uniform, so as to avoid the phenomenon of the expansion rod and the expansion bead breaking caused by improper use. Due to the friction and heat with the pipe, it will change the mechanical properties, and the tube expander should be used alternately and some lubricating oil should be added appropriately to extend the service life. Operation with a ratchet wrench (manual) or connector (electric) set on the square head of the expansion rod, clockwise rotation, to meet your required process requirements, reverse direction can exit, electric tube expansion machine has a reversal device, adjustable tube expansion, should first adjust the required position and depth, and then, according to the above steps to expand the tube after completion. After use, clean the expander that can be used again with butter or oil, put it into the toolbox, and store it in a dry place, avoid moisture and rust.
