PIPENET
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.
