How are exhaust piping connections typically made?

Exhaust piping connections are typically made using welds or clamps due to the need for strong, durable connections that can withstand high temperatures and pressures produced by exhaust gases. Welds create a permanent, solid connection that ensures there are no leaks, which is critical for both performance and safety in exhaust systems. On the other hand, clamps offer the flexibility to easily connect and disconnect exhaust components for maintenance or repairs while still providing a secure seal to prevent exhaust leaks. This combination of methods provides the robustness and reliability required for exhaust systems in various applications, including automotive and industrial environments.

Other connection methods, like screws or bolts, may not provide the necessary temperature resistance or tight seal and could lead to exhaust leaks. Rivets or adhesives are generally unsuitable for high-heat applications, while snap fittings are typically not used in exhaust systems due to their potential for insufficient sealing under the high-pressure and high-temperature conditions of exhaust flow.
