The pipes are produced by Astral Ind. to the highest standard possible to satisfy the market demands and requirements. As temperature increases, the maximum working pressure of the pipes should be reduced. The following table gives the recommended maximum operating pressures for all PP-R pipes.
Main Advantages
Quality
Raw materials meet the requirement of DIN, TSE, ISO 9002 standards.
Chemical & Mechanical Endurance
Compared to traditional plastic piping systems, PP-R offers 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.
Environmentally 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.
