3

Joint

PE pipe is normally joined by butt fusion method which creates a joint that is as strong as or stronger than the pipe itself, and is virtually leak free.

4

Leak Proof

Butt-fused joints Create a homogenous, monolithic joint leading to leak proof system.

5

Corrosion

Resistance &

Biological Effects

Does not rust, rot, or corrode. RFL HDPE pipes are non-conducting and inert and hence immune to galvanic and electrochemical corrosion. RFL HDPE pipes do not rust or corrode, both inside and outside. PE Pipes do not degrade due to biological effects. They am not digestible and do not contain ingredients that would attract animals like rodents. The expectation ally smooth and flexible surfaces of the RFL HDPE pipes do not offer any abrasion effects to rodent's teeth like steel, Cl

6

Chemical Resistance

PE pipe has excellent chemical resistance.

7

UV Protection

Black PE pipe containing 2% (Max) carbon black can be safely used outside in the sun without damage from UV exposure.

8

Impact & Toughness

Tough and good impact resistance.

9

Pressure Ratings & Diameter

PE pipe is available in various sizes up to 1400 mm dia. And pressure rating of PN-6, PN-8, PN-10, PN-12.5, PN-16 and PN-20.

10

Lightweight

It is lighter than Metal or concrete pipe.

It is easier to handle & install as compared to above materials.

11

Flexibility

PE pipe can be bent to a minimum radius of 20 to 40 times the pipe diameter. This flexibility of PE pipe allows Ito be curved under, over & around obstacles as well as directional changes.

12

Coiled pipe

PE pipe is also available in coil from up to 75 mm dia. With specific SDR.

13

Earth Quake / Soil settlement resistance

Found good in case of earth quake and soil settlement. RFL HDPE pipes have excellent resistance to environment stress cracking which is due to the combined actions of stress and the environment. The stain ability of RFL HDPE pipes under stress is higher than any conventional pipes, thereby the pipes never fail due to prism loads and soil settlement due to seasonal changes.

14

Water hammer

The water hammer effect in the RFL HDPE pipes are the lowest when conventional 1pipes for similar operating conditions, thereby reducing the safety appurtenances in the system as well the cost of maintenance.

15

Average E-Modulus (MPa)

900 to 1200 MPa.
