What is the Safety Factor (SF) or aggregate pipe coefficient (C)?
For the transport of water through a pipe system, calculations are performed using an aggregate pipe coefficient (C) = safety factor (SF) > 1.25. For the transport of gas in pipe systems an aggregate pipe coefficient (c) = Safety Factor (SF) > 2.0 is used. The aggregate pipe coefficient is comparable to the safety factor (SF) in its size and significance, as it comprises the safety reserves required under certain circumstances when additional loads affect the pipe. For instance, pressure surges, heat stresses during temperature changes, agitations and ground subsidence can reduce internal pressure load capacity. Check our Specification Manual on standards.
