What is a key performance aspect of long radius fittings compared to short radius fittings?

The key performance aspect of long radius fittings compared to short radius fittings is reduced flow resistance. This is primarily due to the smoother transitions that long radius fittings provide when changing the direction of piping systems.

When fluid flows through a pipe, abrupt changes in direction create turbulence, which can increase friction losses and decrease the efficiency of the system. Long radius fittings have a gradual curve, allowing the fluid to change direction more smoothly, minimizing turbulence and reducing resistance. This is particularly crucial in applications where maintaining optimal flow rates is important, such as in industrial processes or HVAC systems.

Additionally, reduced flow resistance contributes to better energy efficiency within the system, allowing pumps and compressors to operate more effectively. Choosing long radius fittings can lead to lower operational costs over time due to decreased energy consumption and wear on system components.
