Under what condition can flex pipe, tubing, or hoses be used in a Halon 1301 system?

The use of flex pipe, tubing, or hoses in a Halon 1301 system is contingent upon their compliance with established approved pressure and material standards. These standards ensure that the components can withstand the pressures associated with the system while also being compatible with the chemical properties of Halon 1301, which is a fire suppression agent.

Using materials that meet these rigorous standards is essential for safe and effective operation; they must be able to handle the specific environmental conditions without degrading or failing. In contrast, simply painting the components, using stainless steel, or limiting their length does not guarantee that they will function properly in the harsh conditions present in a fire suppression system. Meeting the appropriate pressure and material specifications is fundamental for ensuring the reliability and safety of the system as a whole.
