φ16mm Three slot straight pipe expansion tool

φ16mm Three slot straight pipe expansion tool

Usage
The tube plate is closely combined with the tube plate after the tube is expanded, so as to achieve the effect of pressure sealing, no water leakage and no air leakage. After expansion, the inner wall of the pipe has no damage, and the surface of the inner wall of the pipe is smooth and smooth. Widely used in refrigeration, petrochemical, electric power, shipbuilding, metallurgy and other industries of condenser, cooler, heat exchanger, boiler and other pressure vessel manufacturing and maintenance. It can expand the pipes of copper, aluminum, titanium, iron, stainless steel and other materials.

Instructions for tube expansion

Place the tube expander into the expanded pipe (the expansion shell enters about two-thirds), push the expansion rod, turn the expansion rod clockwise (the tube expansion machine should be used as the power source for batch expansion), the expansion rod drives the expansion bead, and the expansion bead drives the expansion shell, and the rotation Angle generated between the inclined groove of the expansion shell and the tube drives the expansion rod along the axis of the tube while rotating; With the gradual advance of the expansion rod with taper, the inner hole and outer diameter of the expanded pipe are gradually expanded, so that it is closely combined with the tube plate to achieve the purpose of connection.
