Products Description
SiSiC air cooling pipes are designed for application in the cooling zone of roller kilns. With a low thermal expansion coefficient, excellent high-temperature creep resistance, and strong resistance to oxidation and thermal shock, they maintain structural stability during long-term operation without oxidation or deformation.
