Please note that i had modelling steam pipeline and Input parameters for high pressure steam pipeline are as below :

Design Code = ASME B31.1
Fluid = High Pressure Steam Pipe Size (Main Steam Header) = 219.1 mm
Design Thickness (Main Steam Header) = 23.01 mm
Pipe Size (Smaller Pipe – Limb) = 88.9 mm
Pipe Thickness (Smaller Pipe – Limb) = 11.13 mm
Design Pressure = 14366 KPa
Hydro Pressure = 21550 KPa
Design Temperature = 545°C
Mill Tolerance = 12.5%
Pipe Density = 0.00764 Kg/cm3
Fluid Density = 0.00004 Kg/cm3
Pipe Material = SA335 P91 (Alloy Steel)
Insulation Thickness = 100 mm
Insulation Density = Mineral Wool (0.00014)


Stress analysis performed at following load cases :

HYDRAULIC
OPERATING
SUSTAIN
EXPANSION

Now i have to analyse this model with WIND & SEISMIC load cases.

Please guide me brief steps for doing WIND & SEISMIC load cases.

Thanks in advance.
