UPVC drainage and irrigation pipe – UV-resistant, durable


Field Notes: Why UPVC Drainage And Irrigation Pipe Keeps Winning in Farms and Municipal Projects

I’ve walked enough farms and half-built municipal trenches to know when a pipe system “just works.” Lately, the quiet workhorse has been the UPVC Drainage And Irrigation Pipe—not flashy, but dependable. From Hebei to the Gulf, installers keep telling me the same thing: stable pressure, clean joins, and fewer callbacks. Honestly, that’s what matters on a sweaty Tuesday afternoon.

UPVC drainage and irrigation pipe – UV-resistant, durable

Industry snapshot

Three converging trends: water scarcity, electrification of pumping (energy costs bite), and the shift to Ca–Zn stabilizer systems (lead-free). In practice, that means more uniform flows at lower pressure, simpler solvent-weld installs, and, surprisingly, fewer algae issues because the inner wall is smooth (k ≈ 0.007 mm).

What it’s made of and how it’s made

  • Materials: PVC resin + Ca–Zn stabilizers, ACR/CPE impact modifiers, internal/external lubricants, carbon-black/UV package (for outdoor lines).
  • Process flow: Resin compounding → extrusion → vacuum calibration → water-cooling → haul-off → cutting → bell/socketing → aging → QC testing.
  • Standards: GB/T 13664—2006; design cross-checked against ISO 1452 and ISO 4422 for dimensional and pressure behavior.
  • Service life: around 25–50 years in real-world use (buried, UV-protected); exposure and water chemistry may shorten or extend this.

Technical specifications (quick view)

Nominal OD SDR Options Pressure Class (PN) Typical Wall (mm)
Φ75 mm SDR 26 / 21 / 17 PN 0.6 / 1.0 / 1.6 MPa ≈ 2.9 / 3.6 / 4.5
Φ160 mm SDR 26 / 21 / 17 PN 0.6 / 1.0 / 1.6 MPa ≈ 6.2 / 7.6 / 9.5
Φ315 mm SDR 26 / 21 / 17 PN 0.6 / 1.0 / 1.6 MPa ≈ 12.1 / 14.9 / 18.7

Range per spec: Φ75–Φ315 mm. Data indicative; real-world use may vary with temperature (best from 0–45°C) and burial depth.

Testing and certifications

  • Hydrostatic: 1.5× rated PN at 20°C, 1 h, no leakage (ISO 1167 method reference).
  • Impact: TIR ≤ 10% (ISO 3127) at 0°C for selected sizes.
  • Ring stiffness: per ISO 9969; meets class requirements for SDR 17–26.
  • Quality system: ISO 9001; environmental: ISO 14001; RoHS screening by third party.

Where it shines

- Agriculture (drip and sprinkler mains), orchards, greenhouses; - Municipal drainage and stormwater laterals; - Golf courses, sports turf; - Aquaculture and nursery flows. Many customers say solvent welding is faster than gasketed PE for small crews—less gear, fewer surprises.

Customization

Colors (gray/white/blue), lengths 4 m or 6 m, socket or plain-end, printed logos, perforated drain options, UV package tuning. I’ve seen projects ask for traceable batch codes—makes warranty talk simpler.

Vendor comparison (field-level view)

Vendor Certs Lead Time MOQ OEM/Color Price Index
Lida Plastic (Hebei, China) ISO 9001/14001, RoHS 10–20 days ≈ 1×20' container Yes / multiple $$
Regional Brand A ISO 9001 15–30 days Flexible Limited $$$
Local OEM Varies 7–14 days Low Yes $

My take: UPVC Drainage And Irrigation Pipe from Lida hits a sweet spot on lead time and QC documentation, especially for public bids.

Real projects

  • Northern vineyard: swapped aging steel mains for UPVC Drainage And Irrigation Pipe, pump energy down ≈18%, clogged emitters dropped after switching to solvent-welded joints.
  • Industrial park drainage: SDR 26 lines, CCTV-tested after install—leak rate near zero at 48 h hold; contractor said the bell-and-spigot consistency saved a day, which is gold.

Origin: No.316 Pingan West Street, Shunping County, Baoding City, Hebei, China 072250.

Quick install notes

Cut square, deburr, dry-fit, apply primer/solvent cement, quarter-turn insert, hold 30–60 s. Allow cure as per cement data (longer if cold). Pressure test gradually—sounds basic, but rushing this step is where 90% of leaks happen, to be honest.
