    Minimum Factor of Safety (FOS) for small diam pressure lines?

    Hello, I'm trying to determine the validity of an imposed requirement for minimum FOS of 4.0 for a short length (~18") of 1/8" od pressure line. The pressure line routes 10000 MEOP Helium gas to downstream components. The pressure vessel for the gas is designed with FOS of 2.0. The...
