Soil Heat Transfer Modules

Calculate high temperature pipeline temperature decay curve from thermal properties or temperature data.

The temperature is assumed to decay exponentially. The temperature decay can be defined by either a decay length, or decay time. The decay length is only valid provided that the fluid mass flow rate and heat capacity are unchanged. The decay time is valid for any flowrate provided that the fluid heat capacity is unchanged. The overall heat transfer coefficient is calculated relative to the inside diameter of the pipe.

Calculate high temperature pipeline walking due to temperature and pressure cycling using the Pipeng simplified method.

The pipe walking length is calculated from the axial movement of the pipe at the down stream anchor point during startup and shutdown cycling using a simple linear friction model. Refer to the pipe walking reference file (pdf) for more details.
