LPIPE is a powerful hydraulic simulation program for liquid pipelines under isothermal (constant temperature) flow. Despite the complexity of the program it is very user-friendly. Online HELP is available for most data entry screens and the program has extensive error checking features. LPIPE has the following
Significant features: Calculates steady state, isothermal hydraulics of a pipeline transporting a liquid. Liquid can be injected or stripped at various points along the pipeline.
Viscosity units may be in SSU, SSF, centistokes or centipoise.
Liquid gravity may be specified in specific gravity or API gravity.
A built-in database of liquid properties can be revised and updated.
The available pressure drop formulas include Hazen-Williams, Miller, MIT, T.R. Aude, Colebrook-White as well as the Moody diagram version.
The Maximum Allowable Operating Pressure (MAOP) of the pipe can be calculated and automatically inserted in the data file.
The pipeline can have up to five pump stations with pumps in series or parallel at each pump station. Calculations can be performed with or without considering pump curve data. There may be a maximum of 5 pumps at each station. Individual driver HP can be specified.
Detailed pump station definition, such as pumps being turned ON and OFF. Select from available database or create new pump curve data. The amount of pump impeller trims required to minimize throttling can be calculated.
Individual pump curve data can be viewed, edited and plotted on the screen or the printer.
The maximum pipeline throughput for a given MAOP can be calculated for a specified pump station configuration.
The Hydrostatic Test Pressures based on pipe hoop stresses of 90% and 100% Specified Minimum Yield Strength (SMYS) can be calculated. Technical Support:
Free Technical Support is provided for registered users of this software for a period of one year from the initial purchase date. After that period, Technical Support can be provided only if an annual Software Maintenance and Technical Support (SMTP) plan has been purchased. Minor program updates and maintenance releases are posted at SYSTEK’s Web site for licensed users to download free of charge. You may need to contact SYSTEK to obtain a password for downloading and installing an updates from the web site. Major upgrades are issued twice a year at special prices to current licensed users. Call or write for details of SMTP plan.
