Advantages of the PPR System

PPR is increasingly used in thermal and hydraulic installations thanks to its strength, ease of installation, low cost and compatibility with modern piping systems.

Resistance to Chemicals, Abrasion and Electrolysis
: PPR is a non-toxic material suitable for drinking water applications, provided it is used in accordance with applicable regulations and the technical requirements of the project.
It offers high chemical resistance to acidic and alkaline substances, as well as good resistance to abrasion and electrolysis. It also performs well against most chemicals used in water treatment plants, always taking into account the operating conditions of the installation, such as temperature, pressure, chlorine concentration, flow velocity and loads on the network.
These characteristics make the system a suitable solution for water networks, technical installations and circuits where durability and low maintenance are required.
Durability Under Pressure, Temperature and Impact
: The MT PPR system is designed to provide a long service life in installations subject to pressure, temperature and continuous use. Its technical limits include a temperature range from -20°C to 90°C and a nominal pressure rating of PN25. In addition, the fittings have been tested for leak-tightness up to 35 bar, providing reliability in installations subject to pressure and continuous operation.
PPR offers good resistance to impact and deformation. The smooth inner surface of the pipe helps reduce water friction, minimising pressure loss and promoting more efficient flow distribution. Its low thermal conductivity helps reduce heat loss in hot water and heating installations. Its controlled thermal expansion, together with good resistance to impact and deformation, helps maintain a more stable, durable and reliable installation over time.
Fast, Clean and Durable Installation
: The PPR system allows fast, clean and secure installation using heat fusion, creating strong, leak-free connections without the need for metal welding, adhesives or more complex joining systems, reducing installation times.
The lightweight nature of the pipe and fittings makes transportation, handling on site and installation along long runs, service shafts, suspended ceilings and technical rooms easier.
The MT range allows complete installations to be configured with elbows, tees, couplings, reducers, threaded fittings, caps, wall plate elbows, valves and pipe, making it easier to adapt the system to different layouts and connection requirements.
Complete System: Pipe, Fittings and Valves. Available in Green and Blue
: The MT PPR range includes pipe, fittings and valves for complete installations. Working with a complete system facilitates compatibility between components, improves installation organisation and simplifies future maintenance, repair or extension work.
MT offers PPR systems in green and blue, including pipe, fittings and valves. This availability allows the installation to be adapted to installer preferences, visual identification criteria or the organisation of different circuits within the same network.

PPR System Applications

The MT PPR system is a versatile solution for plumbing, domestic hot water, heating, HVAC, geothermal, compressed air and technical water distribution networks.

Plumbing and Domestic Water Installations
: The MT PPR system is suitable for cold and domestic hot water networks in homes, residential communities, hotels, offices, hospitals, schools and public buildings. Its non-toxic, corrosion-resistant material is suitable for water networks and allows safe and durable installations to be developed.
The range of PPR pipe, fittings and valves facilitates the installation of complete networks, with solutions for changes of direction, branches, reductions, threaded connections and shut-off points. In addition, the availability of green and blue PPR helps visually identify different circuits within the installation.
Heating, HVAC and Geothermal Systems
: The MT PPR system can be used in heating, HVAC and geothermal installations where a lightweight, strong solution with good thermal performance is required. Its low thermal conductivity helps reduce heat loss in hot water circuits, while its smooth inner surface helps reduce pressure loss.
It is a suitable solution for technical rooms, residential buildings, commercial premises, tertiary-sector installations and energy-efficiency projects.
Technical Networks and Water Distribution in Buildings
: MT PPR pipe and fittings are an efficient solution for technical water distribution networks in residential, commercial and industrial buildings. Their corrosion resistance, low pressure loss and good durability allow installations designed for continuous use to be developed.
The system is particularly useful in service shafts, suspended ceilings, technical rooms, plant rooms and distribution networks where a lightweight, strong and easy-to-maintain solution is required. In addition, the use of green and blue PPR allows circuits to be identified more clearly during installation, inspections and future extensions.
Refurbishment, Extensions and Installation Maintenance
: Thanks to its lightweight design and ease of installation, the PPR system is a practical solution for plumbing refurbishments, pipe replacement, network extensions and maintenance work in existing buildings.
Heat-fusion connections create strong, leak-free joints, while the wide range of fittings and valves makes it easier to adapt the installation to existing layouts, changes of direction, branches or new connections. This helps reduce intervention times and simplify work in homes, commercial premises, residential communities and occupied buildings.

Frequently asked questions

What pressure and temperature can the MT PPR system withstand?

MT PPR fittings have a nominal pressure rating of PN25 and are designed to operate within a temperature range from -20°C to 90°C. The actual working pressure of the installation will depend on the temperature, application class, type of network and operating conditions.

What are the advantages of PPR compared with copper installations?

PPR does not oxidise, is lighter and is installed using heat fusion, without the need for metal welding or open-flame work. It also has low thermal conductivity, which helps reduce heat loss in hot water and heating networks.

Compared with copper, the MT PPR system also offers good chemical resistance, a lower risk of internal scaling and easier installation in plumbing, domestic hot water, heating and water distribution networks in buildings.

Is the PPR system suitable for domestic hot water?

Yes. MT PPR pipe is designed for cold and domestic hot water installations in buildings. It is commonly used in homes, residential communities, hotels, offices, schools and public buildings, always respecting the pressure, temperature and application class limits of the system.

Can the PPR system be used for heating and HVAC?

Yes. The MT PPR system can be used in heating, HVAC and geothermal installations provided that the design complies with the technical pressure and temperature limits. Its low thermal conductivity, corrosion resistance and smooth inner surface make it a useful solution for hydraulic circuits in technical rooms, residential buildings, commercial premises and tertiary-sector installations.

How are PPR pipes joined using heat fusion?

PPR pipes and fittings are joined using heat fusion, a process that carefully heats the end of the pipe and the inside of the fitting to fuse both components into a single joint.

This process creates a strong, durable and leak-free connection without the need for adhesives, metal welding or mechanical tightening systems.

What is the difference between green and blue PPR?

The main difference is the colour. MT offers green and blue PPR to facilitate visual identification of circuits, adapt the installation to installer preferences or meet organisational criteria on site. Both colours allow compatible pipe, fittings and valves to be used within the MT PPR system.
