Large-diameters fittings & multilayer pipes
Discover our range of brass and PPSU fittings and multilayer pipes up to DN75mm

Large-diameters multilayer systems for plumbing & heating installations
Large-diameter multilayer pipe systems (40, 50, 63, and 75mm) are becoming increasingly preferred over traditional options like metallic or PPR pipes, especially for domestic hot and cold water and heating installations for communal boiler rooms and riser distribution in high-rise buildings. In this context, AIS offers a comprehensive range of large-diameter multilayer pipes and press-fittings.
Our systems, including AIS XPRT, AIS PPSU , AIS Modular press-fittings, paired with AIS multilayer pipes, are designed to deliver more efficient, durable, and reliable solutions up to large diameters projects.
Large-diameters fittings & multilayer pipes benefits
)
BENEFIT
Lightweight, easy-to-handle systems
Large-diameter multilayer systems are lighter than other systems on the market, making them easier to transport, handle, and install. Their reduced weight translates into cost savings by lowering both transportation and installation expenses.
BENEFIT
Saving time
The connection between the pipe and fitting takes less time compared to other systems. Thanks to the press-fitting system, connections can be made directly on-site, significantly reducing installation time.
BENEFIT
Enhance your energy efficiency
AIS Multilayer pipes minimize heat loss due to their low thermal conductivity, reducing energy consumption. In chilled water systems, they prevent condensation thanks to the same properties.
BENEFIT
Low acoustic transmission
AIS Multilayer pipes feature low acoustic transmission, reducing noise from water hammer by up to 60%, improving acoustic comfort even at high water circulation speeds.
Large-diameters fittings & multilayer pipes advantages
Access to data sheetVersatile systems solutions
We offer different systems and a comprehensive range of fittings, including AIS XPRT (brass) up to Ø75mm and AIS PPSU (polyphenylsulfone) up to Ø63mm, as well as our AIS Modular press fittings up to Ø110mm, providing versatile solutions for all installation needs.
Increased installation durability
We offer different systems and a comprehensive range of fittings, including AIS XPRT (brass) up to Ø75mm and AIS PPSU (polyphenylsulfone) up to Ø63mm, as well as our AIS Modular press fittings up to Ø110mm, providing versatile solutions for all installation needs. The aluminium middle layer in AIS Multilayer pipes serves as an oxygen diffusion barrier, safeguarding the metal components of the installation (including production equipment against corrosion), thereby extending their lifespan.
