Note:

1. d = outside diameter of pipe

s = wall thickness of pipe

PN = Nominal pressure rating, in bar at 20ºC

2. Pipe weight per 1 meter is estimated by using pipe density at 0.952 gm/cm³.

3. Standard lenght is 6 meters, but for small size, 16 mm - 110 mm it can be coiled at the length of 50 and 100 m per coil.

Light weight with only 0.95 grams/cm². Weigh only 1/5 of steel pipes of the same size.

High flexibility. Can be bent as much as 25-40 times of the pipe diameters, thus reducing unnecessary pipe joints.

Rust proof and high resistance to damaged chemicals, making the product last up to 50 years.

Super smooth internal surface, reducing the chance of pipe cloggage.

Safe for drinking water with no toxic or chemical contamination.
