Bolts with temperatures above 150 ° C require advanced disc spring pretensioning technology. It is recommended to use this series as much as possible when working at temperatures below 300 ° C and corrosive media.
High tear resistance, high temperature resistance, corrosion resistance, aging resistance, non-toxic and tasteless, good elasticity.
The product is sintered with PTFE and graphite at high temperature. Advantages: low friction coefficient, good compressibility, better wear-resistant; suitable for chemical, petrochemical, hydrocarbon reaction and power plants.
