PPR pipe WT 50x6.9x4000 PN20 GF Wavin 3075178

Polypropylene pipe for water and heating installations

Wavin PPR pipe with fiberglass is a solid and reliable solution for building water supply and central heating installations. Made of high-quality polypropylene, reinforced with a layer of fiberglass, it provides durability and resistance to operating conditions. It is an element of the Wavin PPR system, which is appreciated by installers and users for its ease of installation and long service life.

Construction and properties

The pipe is characterized by a three-layer construction – the inner and outer layer made of polypropylene (PPR) surrounds the middle layer reinforced with fiberglass (GF). This combination of materials minimizes the thermal expansion of the pipe, which translates into installation stability and reduces the need for additional supports. Fiberglass increases the pipe's resistance to pressure and temperature, and also improves its insulating properties. The coefficient of thermal conductivity is 0.24 W/(m.K), which affects the reduction of energy losses in the heating system. The pipe is designed for surface mounting.

Application and benefits

WT 50x6.9x4000 PN20 GF Wavin PPR pipe is used in installations:

• Water supply – transport of cold and hot water.
• Central heating – distribution of heat in heating systems (subject to compliance with installation recommendations).
• Floor heating – ideal for underfloor heating systems due to low thermal expansion (0.035 mm/(m.K)).
• Industrial – transport of liquids and gases (after individual assessment of chemical resistance).

Advantages for the installer:

• Easy and quick installation – PPR pipes are easy to process and connect using welding or crimp fittings.
• Low weight – facilitates transport and installation, especially at heights.
• Dimensional stability – minimizes the risk of deformation and leaks.
• Long service life – the Wavin PPR system guarantees reliable operation for many years (the manufacturer provides a 10-year warranty on standard elements).

Benefits for the user:

• Durability – high-quality materials ensure resistance to corrosion, deposits and mechanical damage.
• Safety – PPR pipes are harmless to health and do not affect the quality of drinking water.
• Quiet operation – reduction of water flow noise thanks to the smooth inner surface of the pipe.
• Low pressure loss – optimal water flow thanks to minimal internal pipe resistance.
