🔹 What is PN? PN stands for Pressure Nominal. It indicates the maximum allowable working pressure of a pipe in bar at the reference temperature of 20°C. Example: A pipe with PN6 can withstand up to 6 bar at 20°C. A pipe with PN16 can withstand up to 16 bar at 20°C.
Differences between Polyethylene Grades: PE63, PE80, and PE100 Polyethylene (PE) is one of the most widely used polymers in pipe manufacturing and underground installations. Due to its light weight, high resistance to corrosion, and long service life, polyethylene pipes have become a suitable replacement for metal and concrete pipes in water supply, sewage, gas distribution, and industrial systems.
