1. Classified by pressure characteristics (widely used in bidding documents)

1. Non-pressure-compensated patch drip tape (standard type) Working pressure: 0.1～0.2MPa. The flow rate changes with pressure fluctuation. Suitable for flat land. Low cost, most widely used in domestic projects.

2. Pressure-compensated patch drip tape Built-in elastic diaphragm. The flow rate remains basically constant within 0.1～0.3MPa. Ideal for sloping land, long-distance laying and plots with large elevation difference. The 55L/h set in previous parameters belongs to pressure-compensated type.

2. Classified by wall thickness

1. Thin-wall type: 0.20～0.30mm, for one-time / short-term use (1 or 2 growing seasons). Used for mulched farmland, recyclable or disposable after use, cost-effective.

2. Thick-wall type: ≥0.40mm, high strength, tear-resistant and aging-resistant, reusable for many years. Preferred for orchards and fixed greenhouses.

3. Classified by dripper outlet hole Single-hole patch: low flow rate, longer laying distance.

Double-hole patch: better anti-clogging performance, hard to be blocked by impurities, commonly used in greenhouses.

4. Common Specifications (Pipe Diameter / Dripper Spacing / Flow Rate) Pipe diameter: DN16 (16mm) as mainstream, DN25 for a small amount;

Dripper spacing: 10cm, 15cm, 20cm, 30cm;

Flow rate per dripper: 1.0L/h, 1.2L/h, 1.6L/h, 2.0L/h.

III. Main Performance Parameters (Directly for bidding documents)

Working pressure: 0.10～0.20MPa (non-compensated); 0.1～0.3MPa for pressure-compensated type

Flow variation coefficient: ≤7% (national standard, high uniformity of water output)

Structure: PE film tape, with independent patch drippers thermally compounded on inner wall. Each dripper is equipped with filter window and turbulent energy dissipation channel for excellent anti-clogging performance.

Material: PE polyethylene raw material plus carbon black anti-aging formula, UV resistant and acid & alkali resistant.

Features:

• Water & fertilizer saving: Saves 50%~75% water compared with flood irrigation. Fertilizer is applied directly to root zone to greatly improve fertilizer utilization rate.

• Easy installation: Supplied in rolls, can be laid manually or mechanically.

• Disease reduction: Dry inter-row soil restrains weeds, reduces humidity and fungal diseases.

• No damage to soil structure and no soil compaction.
