Details

1. Performance and Use

The device uses the characteristics of high elasticity and high strength of polyurethane elastomer to design the internal support expansion device for the wire machine. When in use, only the conical extrusion ring needs to be pulled, and the wire expansion ring produces uniform radial deformation under the action of the conical extrusion ring, so that it expands the inner wall of the steel pipe to achieve the purpose of centering and tightening the steel pipe. The device is divided into two types (I) and (II), and it is used in conjunction with the Z-type wire expansion ring produced by our company.

2. Working conditions

Working medium: water, emulsion, hydraulic oil; working temperature: -20 ~ +80 ℃.
