Catalogue advantages
No water-hammer & pressure drop
The internal surface of the pipes are smooth, homogeneous, and non-porous. Due to low flow resistance, the pressure drop is less. It has higher flow rates and a wider range of applications with exceptional impact resistance and reduced noise generation.
Long service-life under aggressive working conditions
The quality of the raw material and the high manufacturing technology used to produce them ensure long-life reliable products.
Better flow rate
Compared to normal PN20 PP-R pipes, it has a higher bore size and higher operating pressure at the same operating temperature.
Hygienic, non-toxic & environmentally friendly
All materials used in the production are non-toxic in accordance with current international standards and are completely safe for use with liquid consumables.
