Pipe2020: Steam (Steam Analysis)

Pipe2018: Demo

Pipe2020: Steam analyzes the steady state flows and pressures in steam distribution networks. Flows are steady, one-dimensional, and saturated. Pipe2020: SuperSteam is an advanced version of Steam. SuperSteam was developed specifically for modeling distribution networks designed for superheated steam.
Pipe2020: Steam is useful for determining the effects of demand or load changes. It can accommodate large networks, looped systems, and multiple supply and load points. Several scenarios may be set up in a single model, such as load changes or open/closed valves.
Steam Distribution Models
  • Uses appropriate data from the latest steam tables to calculate the required state parameters (IAPWS-IF97).
  • Automatically balances mass, energy and other thermodynamic equations irrespective of the model complexity.
  • Allows for multiple scenario simulations in one model run, e.g., what-if scenarios, such as:
    • Studying the effect of increasing or decreasing of load factors in a single run.
    • Changing certain model parameters/characteristics, e.g., pipe diameter, pipe roughness, on/off status of a valve, specific load change at any node.
  • Multiple compressors with pressure-flow
  • Multiple pressure reducing valves (PRVs)
  • Multiple steam generating sources (both high and low-pressure stations)
  • User-specified steam loads
  • Wide variety of supported elements & devices
  • Powerful GUI features
  • Reference Pressure – highest supply pressure for the system
  • Global Load – factor that may be applied to assigned loads
  • Pipes – Diameter, Darcy-Weisbach roughness, fittings (bends, T’s, reducers, etc.), length (may be scaled by default)
  • Nodes – Elevations, loads
  • Compressors/Fans – Pressure/flow characteristics or useful power
  • Supplies – Supply pressure or pressure/flow characteristics for variable pressure supplies
  • Loss Elements – Loss/flow characteristics
  • Regulators – Pressure setting
  • General – No initial flow or pressure assumptions are required. Any number of parameter changes may be made within the same analysis. At least one fixed pressure node or reservoir is required for each system.
  • Low pressure areas are highlighted
  • Highest mach number (indication of choking condition) and the pipeline in which it occurred is listed
  • Summary of results including total load in the system
  • Flows in/out of each supply/receiving node
  • Detailed report on pressure reducing valves (PRVs), flow rates, specified pressure setting, pressure drop
  • Detailed report on compressor operation
