What is the minimum inside diameter for factory installed tubes on station inlets?

The minimum inside diameter for factory-installed tubes on station inlets is 3/8 NPS. This specification is crucial because it ensures that the medical gas systems can efficiently deliver the necessary flow of gases for patient care. The 3/8 NPS size strikes a balance between adequate gas flow and manageable pressure drop, ensuring that essential gases like oxygen, nitrous oxide, or other medical gases reach their destinations effectively without excessive loss of pressure.

Using a diameter that is too small could restrict the gas flow, potentially leading to inadequate supply to medical equipment or patients. On the other hand, a larger diameter would not only increase costs but might also complicate the installation process without offering significant benefits in standard applications. Thus, adhering to the standard of 3/8 NPS helps maintain system efficiency and safety across various medical settings.
