FLEX© HDPE Pipe

Flex HDPE pipes are produced as per various International Standards. Special pipe are also produced meeting specific requirements of the clients.

FLEX© HDPE

Flex HDPE Pipe is a type of flexible plastic pipe used for fluid and gas transfer and is often used to replace ageing concrete or steel mains pipeline.

FLEX© HDPE

PROPERTIES

Flex HDPE Pipe is a type of flexible plastic pipe used for fluid and gas transfer and is often used to replace ageing concrete or steel mains pipeline. Made from the thermoplastic HDPE (high-density polyethylene), its high level of impermeability and strong molecular bond make it suitable for high pressure pipelines. PE100 is the third generation of pipe grade PE. It has an optimum balance of three key properties: Minimum Required Strenght (MRS) – this provides long term strenght and creep resistance. On the other hand HDPE is more able to withstand and dampen (mitigate) shock waves than PVC….While PVC is a heavier and stronger material, HDPE is harder and more heat and abrasion resistant.

Mining Applications

Corrison Resistant

High Density Polyethylene (HDPE) – HDPE is a corrison resistant plastic that offers an increased working temperature range and higher tensile strength when compared to Low-Density Polyethylene (LDPE).

UV Resistant

Carbon black, utilized in most HDPE pipes is the most effective ultraviolet stabilizer and therefore, black is the recommended pipe colour for exposed long term service or storage. Pipe of this color will provide decades of outdoor use similar to that of black power-line cable jacketing.

Safe for Health

HDPE is reported to be one of the “good” plastics, safe for use with food and water. Independent studies have shown that organic contaminants leach from HDPE pipe into water. HDPE isn’t necessarily dangerous in its final form, once its been moulded or maufactured into the container or product that it will continue to be used for until eventually being recycled… However it should be noted that while all food-safe containers are made from HDPE, not all HDPE is food safe.

Eco Friendly

Products made from Type 2 HDPE recycled plastic are considered Eco-Friendly because they are made mainly from post-consumer products and are recyclable at the end of their useful life… HDPE plastic is the most enironmentally stable of all the plastics – giving off no harmful fumes into the environment.

PRESSURE NOMINAL – PN

PE Pipes are produced in different pressure grades (PN Grades), which indicates the pressure in bars the pipe can support with water at 20°C. The pressure grades available according to European standards are as follows:

PN 2.5 – max pressure 2.5 bar

PN 4 – max pressure 4 bar

PN 6 – max pressure 6 bar

PN 10 – max pressure 10 bar

PN 16 – max pressure 16 bar

1 bar = 10 Pa (N/m²) = 0.1 N/m²= 10,197 kp/m²= 10.2 m H, O = 0.9869 atm = 14.50 psi (lb/in) = 10° dyn/cm²= 750 mmHg

SDR

“Standard Dimension Ratio” SDR – SDR The ratio of pipe diameter to wall thickness (SDR = D/s) where D= Pipe Outside Diameter (mm, in) s = pipe wall thickness (mm, in) SDR 26 (Diameter is 26 times the wall thickness)
