The two-part ring K 81150 is a robust fastening and positioning component developed for exhaust piping systems in the Sulzer ZV40/48 engine. Designed as a split construction for easier installation and maintenance, it provides secure clamping and alignment of exhaust pipe connections under high-temperature operating conditions. The ring is engineered to withstand thermal expansion, vibration, pressure fluctuations, and mechanical stress commonly present in marine and stationary diesel engine exhaust systems. Manufactured from heat-resistant and corrosion-resistant materials, it maintains structural integrity and reliable fastening performance over extended service intervals. Its precision-machined contact surfaces ensure accurate positioning and even load distribution across the exhaust assembly. By supporting secure exhaust pipe connections and reducing the risk of leakage or misalignment, the K 81150 ring contributes to safe operation, efficient exhaust gas flow, and long-term durability of the exhaust system.
