Four networks,
one pipe.
Irrigation mains
The pressure backbone feeding GeoFlow subsurface drip across 50–500 ha projects. PN 12.5 for typical 6–8 bar pumps; PN 16 for long mains and capacity reserve.
Drinking-water networks
Certified for potable contact (Rospotrebnadzor conclusion). Smooth bore (Hazen-Williams 150) and a thinner wall give 25–30% more throughput than HDPE at the same nominal.
Fire-suppression
Pressure networks with an EMERCOM conclusion in the manufacturer package. The 1.5× safety factor handles transient water hammer.
Pumping networks
High-pressure transfer with PN 20/25 classes for demanding industrial duty, with capacity reserve for water hammer.
Pressure class by duty.
The standard class for typical farm irrigation mains.
Safely takes transient pressure to 24 bar with the 1.5× factor.
Reserved for high-pressure pumping and demanding duty.
DN 90–500 standard; custom to DN 1200 for trunk mains.
Push-fit. 50 years. No welder.
The push-fit rubber-gasket joint cuts install time 40–60% versus welded HDPE and needs no fusion equipment — section replacement takes 10–20 minutes and phased expansion is a simple tee or coupler. With a 50-year warranty against HDPE's typical 15, the 15-year total cost of ownership is 60–75% lower.
What pressure class should I specify?
PN 12.5 covers typical 50–200 ha farm irrigation mains on 6–8 bar pumps. Move to PN 16 for long mains, capacity reserve or significant water-hammer risk — it safely takes transient pressure to 24 bar with the 1.5× factor. PN 20/25 is reserved for high-pressure industrial pumping.
Is GEO-PVCo certified for drinking water in Russia?
Yes — the manufacturer package includes a Rospotrebnadzor conclusion for potable contact, and an EMERCOM conclusion for fire-suppression networks. The pipe is produced to ISO 16422 / EN 17176-2 and carries EAEU certification.
How does install compare with welded HDPE?
The push-fit rubber-gasket joint needs no fusion equipment or welder and cuts install time 40–60%. Section replacement takes 10–20 minutes and phased expansion is a simple tee or coupler.
What is the warranty and lifecycle cost?
GEO-PVCo carries a 50-year warranty against HDPE's typical 15. Combined with the faster install and easier maintenance, the 15-year total cost of ownership runs 60–75% lower than welded HDPE.
