- Thepolyurethane elastomer has the advantage of high elasticity, high strength characteristics.
- When the steel pipe is not fixed, there is a certain gap between the expansion ring and the steel pipe. It is easy for installation and dismantling. When the steel pipe is fixed, the expansion ring expands tightly with the inner wall of the steel pipe by the extrusion pressure of the expansion ring.
Working medium: water, emulsion, hydraulic oil
Working temperature: -20 to +80℃
