How the dual-layer structure works as one system
An introduction to the inner waterway, outer protection and connection nodes of an AES piping system.
The AES system uses an austenitic steel inner layer as the waterway, while the PPR outer layer provides environmental protection and thermal support. Each material has a distinct role.
Connections are part of the system design. Selection should consider pipe size, fitting type, installation process and future maintenance access together.
For each project, material and connection choices should also reflect water quality, pressure, temperature and installation conditions so every component works together.
