Robust PE pipes for agriculture, horticulture and landscaping. UV-stable, flexible and durable. Discover PE-LD and PE-HD solutions for efficient irrigation.

Irrigation solutions: efficient systems for agriculture and landscaping

In modern agriculture and landscaping, three factors matter: fast installation, maximum mechanical robustness and UV stability. OHM irrigation pipes are designed specifically for these requirements. Thanks to the flexibility of polyethylene, even complex routes can be realized without extensive fittings.

Our pipe systems resist fertilizers and microorganisms, making them an ideal choice for service water and irrigation networks. Whether for frost protection irrigation in orchards or subsurface irrigation for sports facilities — OHM provides the technological foundation for stable plant growth.

Key safety features & benefits at a glance

Corrosion free

Unlike metal systems, no scaling or rusting due to calcareous well water.

Weather resistance

Year‑round usability with good frost resistance (when properly drained) and UV stabilization for above‑ground installation.

Smooth inner pipe

Minimal friction losses ($k \approx 0.01$ mm) enable longer laterals at the same inlet pressure.

Cost efficiency & installation methods

Easy handling reduces labour costs during installation:

  • Agriculture: ideal for hop cultivation, vineyards and field irrigation. Pipes withstand high tensile loads.
  • Landscaping: perfect for automated irrigation systems (e.g. with geared sprinklers).
  • Frost protection: special HD‑PE variants for overhead irrigation in orchards.
  • Jointing: compatible with common compression fittings, push‑fit fittings and electrofusion (HM).
