Info

Factors that Affect <strong>Nozzle</strong> <strong>Loads</strong> • Temperature – Affects expansion <strong>of</strong> piping/equipment • Pressure – Affects pipe stiffness (more pressure = thicker pipe) • Client piping layout requirements – Valves at grade or overhead – Maintenance access • Steel / Support locations available • Baseplate design 8
Stress Engineering Tools • Stress engineers use specialized FEA s<strong>of</strong>tware packages to do calculations (AutoPIPE ® , CAESAR II) • Allows engineer to build a 3D model <strong>of</strong> <strong>the</strong> piping system, add supports, temperature <strong>and</strong> pressure information, <strong>and</strong> see how <strong>the</strong> piping reacts • Shows movement <strong>of</strong> <strong>the</strong> pipe, stresses on <strong>the</strong> pipe, <strong>and</strong> loads on supports <strong>and</strong> equipment flanges • AutoPIPE ® Break… – 6x4 OH2 Pump – Flow = 909gpm, Head = 426ft, HP = 150hp 9
