What is the maximum bend arc allowed for steel gas piping?

The maximum bend arc allowed for steel gas piping is 90 degrees. This limit is established to ensure that the gas flow remains efficient and that the integrity of the piping system is maintained. A bend that exceeds 90 degrees can lead to significant pressure drops, disrupt the flow of gas, and create potential points of stress that might compromise the system over time.

In practical applications, a 90-degree bend allows for adequate maneuverability in the piping layout while minimizing the risks associated with tighter bends, which could lead to leaks or rupture. It is important to adhere to this standard for safety and performance reasons in any gas piping installation to comply with codes and regulations.
