￠ 191-￠15210 Five slot straight tube expander

￠ 6*0.5-￠76*3 Three slot straight tube expander 

[Specification]:

￠ 19*1-￠152*10

[Purpose]:

Only the inner diameter of the tube ≥φ17 can be used to expand the tube, it is compared with the three-bead expansion, because of the more two beads, the friction resistance is reduced, the expansion of the tube is obviously labor-saving, the inner diameter of the tube after expansion is round and positive, and the bead is not easy to break, especially suitable for the expansion of the tube wall below 0.7mm thin wall and large diameter thick wall tube.
