I.Performance and Purpose

The polyurethane elastomer has high-strength, hardness and good flexibility. Taking advantage of this kind of characteristics to design the expansion ring and strain device which just can pull conical extrusion ring, the polyurethane elastomer — the expansion ring engenders uniform radial deformation by the action of conical extrusion ring, which makes the hole of steel pipe tight in order to fixed steel pipe and centering. It is mostly used for supporting the steel pipe on pipe-threading machine.

II.Material: Polyurethane

III.Design standards

Consult GB/T3672.1-2002 tolerance

IV.Sample order mark

Marked the model and Order No. of expansion ring, Only order No. is also permitted.

Example:ModelZ3-1/2 Order NoZ224

V.Structure of device
