Rain caps are absolutely necessary for the exhaust pipe of each ship. They keep the water away from the funnel case. At the same time our rain caps allow the warm air of the engine room to escape upwards. SB Broneske provides rain caps for vertical and in addition for horizontal exhaust pipes. Both rain caps are specially designed according to their requirements and to minimize the structure-borne noise at the funnel top.
Only rain caps for horizontal installation effectively protect the funnel against rain and splash water. A horizontal exhaust pipe in the funnel case requires a special design of a rain cap.
SB Broneske rain caps are available from DN40 to DN3200. Thus, our rain caps cover the complete spectrum of exhaust pipes.

SB Broneske develops different and customised solutions for the funnel top. Considering results of inhouse 3D printing, FEM (Finite Element Method) analysis for vibration, flow or structure, we develop the best solution for the customers. We expanded our portfolio with adapted CFD (Computational Fluid Dynamics) simulations. The CFD and FEM analysis gives our experts the possibility to provide our customers with the best possible support and high quality results.
Our exhaust gas flaps are very relyable and in service over the last 20 years. They prevent the rain or splash from getting into the exhaust pipe system. Exhaust gas flaps are used to cover the vertical open ends of the exhaust pipe system. The special exhaust gas flap protects the engine and the exhaust pipe system against corrosive influences of rain and snow. Our exhaust gas flaps adjust to the operating status of the engine: They open or close while the engine starts or turns down.
The exhaust gas flaps are available from DN32 to DN3500 (stainless steel) and from DN100 to DN500 (mild steel). SB Broneske is also able to manufacture customized exhaust gas flaps. Additional sizes and materials are available on request.
Inhouse CFD and FEM analysis of the exhaust gas flow at the funnel top
CFD and FEM simulations enable us to respond even more specifically to customer requirements and exploit optimisation potential. The CFD and FEM analysis enables us to identify and exploit potential for improvement in early development phases. The analysis supports our engineers in the development and daily work. The use of these tools gives us the possibility to provide you with the best possible support and high quality results.

We offer a solution by providing stainless steel mesh cushions and instructions for the in-house production of the water protection.
However, this solution has some limitations regarding sustainable vibration and noise reduction.
When constantly overloaded, the cushions conductibility will decrease while structure-borne noise increases.
