High strength ( MRS - 8 N/sq. mm.)
High working pressure
at same thickness : - A pipe of PE 80 can withstand more
working pressure than a pipe of PE 63 with the same thickness.
Lower wall thickness at same working pressure
: - A pipe of PE 80 having lower wall thickness than
a pipe of PE 63 can withstand same working pressure. Due to lower
wall thickness high rate of flow can be achived. Also weight is
reduced.
Bigger pipe dimensions producible
High resistance against RCP : -
Rapid Crack Propogation, rapid crack is propogated due to the internal
pressure of the fluid. PE 80 is having high resistance against RCP
as compared to PE 63
High resistance against SCG : -
Slow Crack Growth, slow crack is produced on the surface of the
pipe due to any notch or external damage. PE 80 is having high resistance
against SCG as compared to PE 63
