Inputs for configuring the pipeline transport system are entered on the Config parameter screen. The following parameters are available:

•Pipeline Region: This is the pipeline region chosen on the Transport Region CONFIGURE SESSION screen. It is shown here for reference.

•Design Option: This is the ASME B31.12 design methodology used in the pipeline design calculations. The selected option determines the applicable design factors and design requirements.

•Class: This is the location class of the pipeline route as defined by ASME B31.12 based on population density and development along the route. The selected class affects the allowable design factor and pipeline design requirements.

•Minimum Yield Strength: This is the specified minimum yield strength of the selected pipe material. It represents the stress at which the material begins to deform permanently and is used in the pipeline thickness calculations. (See note below.)

•Longitudinal Joint Factor: This is the weld joint efficiency factor for the pipe seam. It accounts for the strength of the longitudinal weld relative to the base pipe material and is used in the pipeline thickness calculations. (See note below.)

•Temperature Derating Factor: This factor accounts for the reduction in pipe material strength at elevated operating temperatures and is used in the pipeline thickness calculations. (See note below.)

•Inlet Pressure: This is the inlet pressure for the transport system.

•Inlet Flow Rate: This is the mass flow rate for the transport system.

Note regarding Minimum Yield Strength (SMYS), Longitudinal Joint Factor, Temperature Derating Factor, and Erosional Velocity Limit:

Although these parameters can be varied individually in the software, doing so without consistently updating the associated specifications, design assumptions, or constraints could result in scenarios that are not physically or technically consistent.

For example, changing SMYS while keeping the other material assumptions unchanged would effectively represent a different pipe grade, not uncertainty in the properties of the same selected material.

For this reason, we do not recommend using any uncertainty on these parameters except for batch processing.
