The 1.11 iteration introduces several pivotal upgrades over legacy versions:
The most advanced of the three, this module addresses time-varying or unsteady flow problems . It is used to model complex phenomena such as water hammer, steam hammer, and control system dynamics. Its capabilities extend to calculating hydraulic forces for pipe stress analysis and studying surge alleviation in systems.

Pipenet 1.11 allows for detailed modeling of system components. Users can input specific pump curves to see how the system will behave under various operating points. This is critical for ensuring that the fire pump selected is adequate to overcome the system’s hydraulic demands without over-pressurizing the pipes. The software also allows for the modeling of check valves, pressure-reducing valves (PRVs), and backflow preventers.
PIPENET is a commercial software package distributed through authorized channels. Sunrise Systems Limited holds ISO 9001 certification. The software is available in multiple languages, including English. In China, authorized partners such as Woshan Technology (Beijing) Co., Ltd. and Wanbo Ruisheng (Tianjin) Technology Co., Ltd. provide promotion, technical support, and sales.
, developed by Sunrise Systems Limited, is a leading software suite for fluid flow analysis of pipe and duct networks. Released around early 2021, this version introduced significant technical enhancements to improve calculation stability, data security, and user accessibility across its three core modules. Core Modules and Applications
pipenet --version
PipeNet 1.11 maintains a decoupled architecture to ensure high availability and horizontal scalability. The ecosystem consists of three primary components:
The "Libraries" are where users define the specific characteristics of components in their system, such as pipes, fittings, fluids, and valves. A model must be defined in the libraries before it can be selected for use in the "Init" section. Once the model is built, the powerful calculation engine can analyze even the most complex systems.
PIPENET Vision 1.11 comprises three independent modules, each licensed separately or in any combination:
