Properties of polypropylene fittings

The availability of PPR fittings in an assortment of sizes and configurations permits their application in a variety of systems. Their diameter range of 20mm to 110mm provides versatility for any given undertaking.

Fittings can come in a variety of shapes, such as:

• corner;
• straight;
• tees;
• transitional and others.

Significantly advantageous is the fact that the connectors are constructed from premium polypropylene. Designed for use in plumbing and heating systems, they are exceptionally resistant to high pressure and temperature. Non-toxic substances are not released into the water, and PPR fittings also adhere to drinking water safety standards. Furthermore, their resistance to solvents and substances guarantees their longevity and excellence.

Working pressure and temperature conditions of PPR fittings

The high resistance to heat exhibited by PPR fittings enables their application in systems subjected to substantial temperature loading. The temperature range is size and variety dependent. The components can generally function in temperatures between 0°C and 95°C. It is essential to note, nevertheless, that elevated temperatures can decrease the utmost working pressure. In high-temperature applications, adherence to the designated temperature limits is imperative for the system to function securely and dependably.

To ensure proper selection and utilization of fixtures, knowledge of their operating pressure and temperature conditions is essential:

• The maximum working pressure depends on their size and type.
• Typically, the maximum pressure for PPR fittings is between 16 and 25 bar.
• When used in high-pressure systems, the prescribed limits must be observed to ensure safe and reliable operation of the system.
