FEATURES:
-
Resistance to chemicals – Exceptional resistance to all external & internal corrosion.
-
Resistance to electrolyte corrosion.
-
Will not rust or rot.
-
Welded joints speed up installation trench widths reduced which leads to saving in the cost of excavation and back filling.
-
Smooth bore provides less head loss. Flow resistance is approximately 30% less than that conventional pipe, permitting the use of a smaller bore pipe for a given rate of flow.
-
High impact strength.
-
High reliability and proven service performance.
-
Greater flexibility, light weight, easy & economical installation.
-
Very good thermal insulation due to low thermal conductivity.
-
Flame resistance classify the material as self extinguishing according to test standard employed.
-
Perfect stability of material obviates the risk of ageing and ensures long service life.
APPLICATIONS:
-
These pipes are used for water mains & services and for water supply over & underground and, both inside & outside building.

NOTES:
-
1 Bar = 0.1 MPa = 1 N/mm².
-
Tolerances on wall thicknesses are calculated from (0.1 * eMin + 0.1) mm rounded up to the next 0.1 mm.
-
For practical reasons, a minimum wall thickness of 2.0 mm is recommended.
-
All pressure ratings are calculated at 27°C and rounded up to nearest pressure class.
-
Considering operational problems, maximum wall thickness of pipes is considered around 130 mm.
