How are exhaust piping connections usually made?

Exhaust piping connections are typically made using welds or clamps because these methods provide a secure and durable connection that can withstand the high temperatures and pressures associated with exhaust systems. Welds create a permanent bond between the pipes, ensuring that there are no leaks and that the system maintains structural integrity. Clamps, on the other hand, offer flexibility, allowing for easier assembly and disassembly during maintenance or repairs while still providing a tight seal.

In contrast, using nuts and bolts might not provide the necessary heat resistance and may leave room for exhaust leaks. Sealing tape is generally inadequate for high-temperature applications like exhaust systems, as it may degrade over time and fail to contain exhaust gases. Flanges can be involved in exhaust piping systems, particularly for connections that need to be removable, but they are not the primary method. Instead, welds and clamps are more commonly used for secure and effective exhaust connections.
