- Slippery inner surface — no organic or inorganic sediment build-up
- Composition
- 3 layers (outer & inner layer of PP-R, thermal insulated middle layer)
- Pressure rating
- 20 bar (PN10/20)
- Length
- 4 metres
- Colour
- White
- Manufactured to
- KS ISO minimum requirements
Advantages
Thermal resistance
Have better thermal resistivity than standard PP-R pipes.
Chemical & mechanical endurance
Very high resistance against abrasion by hard particles. This is especially important in cases of well water or industrial applications, where the transferred liquids may contain abrasive particles.
Corrosion and chemical resistance
These pipes are resistant to corrosion and aggressive environment; their transmission capacity is high due to smooth inner surface.
Environmental cleanness
Polypropylene does not react with water, therefore, does not add any taste to the water. Since their inner surface is slippery, organic and inorganic sediments and impurities are not observed.
Durability
It can endure the temperature and pressure strain of hot water systems. At the same time it is able to structurally withstand impacts even in cold weather installations without any risk of cracking or breaking, unlike other common types of plastic piping.
