HDPE pipe extrusion line

Corrosion-free conveyance.

HDPE extended the same extrusion discipline we had built for cable into water infrastructure. The appeal is simple: it does not corrode, it does not scale, and jointed correctly it stays leak-free for decades. For buried irrigation networks that matters far more than initial cost.

The grade decision is the one worth understanding. For the same pressure class, a higher PE grade needs a thinner wall — at OD 110 and PN 10, PE 63 needs 12.3 mm, PE 80 needs 10.0 mm and PE 100 needs 8.1 mm. That is roughly a third less material for the same duty, which changes both the price and the handling weight.

Pressure classes by grade

Pressure classes by PE grade — IS 4984

Material grade	Pressure classes offered (PN)
PE 63	2, 2.5, 3.2, 4, 5, 6, 8
PE 80	2.5, 3.2, 4, 5, 6, 8, 10, 12.5, 16, 20
PE 100	4, 5, 6, 8, 10, 12.5, 16, 20

The number in the grade is the minimum required strength in bar × 10 at 50 years and 20 °C. The pressure ceiling rises with grade: PE 63 tops out around PN 8, PE 100 reaches PN 20.

Which PE grade should I specify?

For the same pressure class a higher grade needs a thinner wall and therefore less material. At OD 110 and PN 10, PE 63 needs 12.3 mm of wall, PE 80 needs 10.0 mm and PE 100 needs 8.1 mm. PE 100 costs more per kilogram but usually less per metre at the same duty, and it is lighter to handle.

What does PN mean?

The nominal pressure rating in bar at 20 °C — PN 10 means the pipe is rated for 10 bar continuous internal pressure at 20 °C for its design life. Derate for higher operating temperature.

Do you supply in coils or straight lengths?

Both. Smaller diameters coil, larger diameters ship straight in 6 to 12 metre lengths. We will confirm the changeover diameter for your size.

How is HDPE pipe jointed?

Butt fusion for larger diameters, electrofusion where a fitting is needed, and compression fittings on smaller irrigation sizes. Correctly fused joints are as strong as the pipe wall.
