The Leading Standard in Pipeline Flow Analysis
Trusted by oil and gas, fire safety, shipbuilding, and power generation companies worldwide for over 25 years. From initial design stages — including pipe sizing and pump selection — to pipe stress analysis and support design, PIPENET is an indispensable tool for engineers designing industrial piping systems.
Versions
Standard version for steady‑state calculations, Spray/Sprinkler for fire safety system design, Transient for simulation and analysis of transient phenomena in pipelines. The three modules complement each other, covering the entire design workflow for industrial piping systems.
PIPENET® Vision Standard Module
A module for steady‑state flow analysis in pipe networks carrying liquids, gases, and steam. Most widely used for utility system design (cooling water, steam, compressed air), HVAC systems, and general piping networks. Supports both compressible and incompressible flow, with two primary calculation methods: Hazen‑Williams and Darcy‑Weisbach.
PIPENET® Vision Spray/Sprinkler Module
A specialized module for fire protection system design. Fully compliant with NFPA 13, NFPA 15, and NFPA 16 standards, covering system types including sprinkler, deluge, ringmain, foam solution, and foam concentrate. Features exclusive Autolayout functionality for automatic pipe routing, significantly reducing design time. Widely applied on offshore platforms, FPSOs, petrochemical plants, refineries, vessels, and aircraft hangars.
PIPENET® Vision Transient Module
A module for analyzing transient dynamic phenomena such as water hammer and steam hammer. A compact yet powerful tool that enables simulation of abnormal scenarios: emergency valve closure, pipe rupture or burst, and changes in pump operating conditions. The key output is a force‑time history file — which can be exported directly for use in pipe stress analysis and finite element analysis (FEA) software.

PIPENET is regularly updated with new features to maintain its position as a technology leader in piping design. Users always have access to the latest versions, incorporating advanced calculation methods including Hazen‑Williams and Darcy‑Weisbach.
Flexible Data Import & Export
PIPENET supports data input in isometric or orthogonal formats, enables easy export of results in tabular or schematic form, and generates intermediate time‑history files compatible with finite element analysis (FEA) and other stress analysis software.
Key Technical Features of PIPENET
A comprehensive set of calculation tools for the design, analysis, and simulation of industrial piping systems.
Three Specialized Modules
PIPENET provides three dedicated modules
- PIPENET Standard: Steady‑state flow analysis for liquids, gases, and steam — including HVAC systems, process piping, and utility networks.
- PIPENET Spray/Sprinkler: Fire protection system design compliant with NFPA 13, NFPA 15, and NFPA 16 — covering automatic sprinkler systems, deluge systems, ringmains, foam solution, and foam concentrate systems.
- PIPENET Transient: Dynamic phenomenon analysis — water hammer, steam hammer, transient hydraulic force calculation, and export of force‑time history files for pipe stress analysis.
Multi‑Method Hydraulic Calculation
Users may select between two standard calculation methods. The software also simulates cavitation, checks for flashing, corrects for altitude‑dependent atmospheric pressure variation, and computes hydraulic gradients.
- Hazen‑Williams: Widely used for water supply and fire protection system design.
- Darcy‑Weisbach: High‑accuracy method for analysis of liquid, gas, and steam flow under complex operating conditions.
NFPA‑Compliant Fire Safety System Design
The PIPENET Spray/Sprinkler module is the global standard for fire protection system design, particularly in oil & gas, LNG, power generation, chemical processing, shipbuilding, FPS, CCUS, and hydrogen industries.
- Solves hydraulic analysis problems per international and local standards.
- Exclusive Autolayout feature reduces design time by days.
- Supports calculations for: fire pump capacity, pump selection based on manufacturer performance curves, and orifice plate sizing.
Transient & Water Hammer Simulation
The PIPENET Transient module is a lightweight, fast‑analysis tool for
- Surge pressure analysis (pressure transients / water hammer / steam hammer).
- Modeling of process control systems.
- Transient hydraulic force calculation and generation of force‑time history files for pipe stress analysis software.
- Simulation of emergency valve closure and pipe rupture or burst events.
- Definition of time‑dependent boundary conditions.
Data Exchange & Software Integration
- Input data in isometric or orthogonal formats; direct copy‑paste from spreadsheets.
- Import background drawings for system schematics.
- Export results as data tables or visual diagrams.
- Generate force‑time history files for finite element analysis (FEA) and stress analysis applications.
- Spreadsheet‑compatible data entry tables support copy‑paste operations.
Advanced Modeling & Customizable Libraries
- Accurate pipe sizing for entire networks.
