Sector Plate Seal
The Sector Plate Seal is a key wear part in the preheater sealing system. For wholesalers, it offers high reorder potential as customers replace it annually during major maintenance. Each seal strip is precisely shaped to match the sector plate’s curvature and features a bent positioning edge for direct installation. It works seamlessly with rotor seal strips.

Key Advantages
1. High Repeat Orders, Core Consumable
The Sector Plate Seal is a key wear part in the preheater sealing system. For wholesalers, it offers high reorder potential as customers replace it annually during major maintenance. Each seal strip is precisely shaped to match the sector plate's curvature and features a bent positioning edge for direct installation. It works seamlessly with rotor seal strips.


2. Exceptional Dust Erosion Resistance
Flue gas carries abrasive dust that can wear down seals quickly. Our Sector Plate Seal uses 1Cr13 or 321 stainless steel, or optional composite wear-resistant alloy plates. Life under dust erosion exceeds 30,000 hours, reducing maintenance frequency and costs. The seal blocks air leakage without causing hard rubbing against the rotor.
3. Precision Fit and Fast Delivery
Laser cutting and bending ensure high dimensional accuracy. Installation flatness is ≤0.5 mm per meter. We can customize the seal based on on-site measurements and provide rapid delivery to meet maintenance schedules.
