PIPESIZE has a large number of features. But it remains easy to use with a clear user interface. Version 3.1 incorporates improved heat gain/loss algorithms and calculates the surface temperature for user-defined insulation thickness as well as the temperature change in the flowing fluid.

Download and review the user manual to appreciate the complete feature set.

Reference Data

You have at your fingertips many more tables with reference information. There are lists of suggested fluid velocities for common liquids, gases and steam. A list of suggested pipe roughness values is provided, with data for new and used pipe ranging from steel to wood.
