Products Description
Spool type expansion joint rubber is usually composed of rubber elastomer, metal flange and reinforcing fibres, etc. It has the characteristics of corrosion resistance, high temperature resistance, anti-aging, etc. Different materials (such as natural rubber, EPDM, neoprene, etc.) can be selected according to the characteristics of the medium and the demand of working conditions. Its flexible design, easy installation, low maintenance costs, and can significantly extend the service life of the piping system. Sleeve type rubber expansion joints provide reliable compensation and vibration damping solutions for pipeline operation under complex working conditions while ensuring pipeline sealing and safety.
