Cylindrical Emitter Drip Tape

OKD AgroTech’s Cylindrical Emitter Drip Line (D-line) is a robust, heavy-wall irrigation solution engineered for long-term agricultural projects. It is specifically designed to deliver precise, uniform irrigation over multiple seasons, providing a reliable and cost-effective alternative to single-season thin-wall drip tapes.

For farm owners, project contractors, and irrigation designers, the primary challenges are often emitter clogging (especially with low-quality water) and the high annual cost of replacing damaged tapes. Our Cylindrical Drip Line directly solves these problems. It utilizes a robust, integral cylindrical dripper with an advanced dual anti-clog mechanism, ensuring system reliability, minimizing maintenance, and maximizing your return on investment.

• Superior Clog Resistance: Features an advanced dripper design with dual individual inlet filters and dual outlets, making it highly effective for unfiltered or low-quality water sources (e.g., well, river, or canal water).
• True Multi-Season Durability: Robust, heavy-wall construction provides outstanding mechanical strength, durability, and resistance to UV radiation, animal damage, and installation stress.
• Excellent Performance Uniformity: Precision manufacturing ensures an outstanding Coefficient of Variation (Cv) ≤ 5% and high Emission Uniformity (EU ≤ 0.5), leading to more consistent crop growth and yields.
• Robust Cylindrical Dripper: The integral “Round Dripper” is inherently more robust and features a larger, turbulent flow path compared to flat emitters, further reducing clogging risk.

Key Technical Specifications (Cylindrical Round Dripper Line)

This technical data provides the precise specifications for our range of Cylindrical Drip Lines. Our engineers and sales team are available to help you select the exact combination of diameter, flow rate, and spacing to match your project’s hydraulic design and crop requirements.

Superior Clog Resistance: The Dual-Filter & Dual-Outlet Advantage

Clogging is the primary cause of failure in drip irrigation systems, leading to non-uniform watering, crop loss, and costly maintenance. Our cylindrical dripper is engineered with a multi-stage defense system specifically to combat clogging, even in tough environments with poor water quality.

Dual Individual Inlet Filters

Each dripper is protected by two separate, large-area inlet filters. This dual-filter design provides a significantly larger filtration surface area compared to single-inlet emitters. This built-in redundancy means that even if one filter inlet becomes partially restricted by sediment or organic matter, the second filter continues to supply water to the emitter, ensuring uninterrupted operation and high clogging resistance.

Dual Outlets In Every Dripper

The emitter features a dual-outlet design, which provides two critical advantages. Firstly, it offers an additional layer of redundancy; if one outlet is ever blocked by an external particle, the second outlet ensures water delivery continues. Secondly, the dual outlets are designed to minimize the “suck-back” of soil or sand particles into the dripper when the system is shut down and pressure drops, a common cause of clogging in subsurface (SDI) or on-surface applications.

Optimized for Low-Quality Water Sources

This combined dual-filter and dual-outlet mechanism, along with a wide, turbulent-flow labyrinth, makes our cylindrical drip line the ideal choice for projects relying on well water, river water, or canal water. It reduces the need for complex and expensive secondary filtration systems and ensures reliable performance season after season.

Engineered for Durability: Heavy-Wall & Multi-Season Performance

The financial viability of a permanent crop or large-scale farm depends on the longevity of its infrastructure. Our drip line is defined by its “Heavy-Wall” construction, offering a robust physical barrier against the primary causes of irrigation failure.

Robust Heavy-Wall Construction

With a typical wall thickness of 0.9mm to 1.2mm, this drip line provides exceptional mechanical strength. It is highly resistant to damage from installation, field machinery, abrasive soils, and animal pests. This makes it suitable for reuse for many seasons and is the required standard for Subsurface Drip Irrigation (SDI) where the pipe is buried. The tough and reliable tube ensures a long service life in the field.

Advanced UV-Resistant PE Material

The drip line is manufactured from 100% premium virgin polyethylene (PE) resin, not recycled material. This base resin is blended with high-grade carbon black and a sophisticated package of UV inhibitors. This formulation provides maximum protection against degradation from solar radiation, ensuring the pipe remains flexible and strong even after years of exposure in the world’s harshest climates.

Precision Irrigation: Unmatched Water Uniformity (Cv ≤ 5%)

For irrigation engineers and professional growers, water uniformity is not a luxury—it is the key to uniform crop yields and efficient fertigation. Our manufacturing process is optimized for precision.

Excellent Manufacturing Coefficient (Cv ≤ 5%)

The Coefficient of Variation (Cv) is a critical measure of manufacturing precision. A Cv of 5% or less is considered “Excellent” by international standards (ISO 9261). It means that the flow rate from any one of our drippers is extremely consistent with the next. This is the mark of a high-quality, precision-controlled manufacturing process that you can trust for your project design.

High Emission Uniformity (EU ≤ 0.5)

This low Cv translates directly to a high Emission Uniformity (EU) in the field. High EU (often expressed as a value > 95% or a low deviation like EU < 0.5) ensures that all plants along the lateral line—whether at the beginning or the end—receive the same, precise amount of water and nutrients. This prevents over-watering (which wastes resources) and under-watering (which stunts growth), leading to more uniform crop development and maximized yields.

Versatile Applications for Professional Agriculture

The durability and anti-clog features of our heavy-wall cylindrical drip line make it the ideal solution for a wide range of long-term and high-value irrigation projects:

• Orchards & Vineyards: (e.g., Grapes, Almonds, Citrus, Apples, Olives)
• Multi-Season Row Crops: (e.g., Vegetables, Cotton, Sugarcane)
• Greenhouses & Nurseries: For long-term, reliable irrigation of benches and beds.
• Landscaping & Public Works: Durable irrigation for parks, medians, and commercial properties.
• Subsurface Drip Irrigation (SDI): The heavy-wall construction is essential for burial and long-term subsurface applications.

Frequently Asked Questions (FAQ)

Q1: What is the primary advantage of this Cylindrical Dripper over a Flat Emitter?

A: The main advantages are durability and clog resistance. Our Cylindrical Dripper is a robust, larger-bodied emitter with a superior dual-filter/dual-outlet system, making it ideal for multi-season use and low-quality water. Many flat emitters are designed for single-season, thin-wall tapes and are more susceptible to clogging and mechanical damage.

Q2: Is this drip line suitable for low-quality water (e.g., well water)?

A: Yes, it is specifically engineered for it. The dual-inlet filter system provides a large filtration area and redundancy, while the turbulent flow path resists sediment and organic matter buildup, making it highly suitable for such water sources.

Q3: What is the expected service life of this heavy-wall drip line?

A: With proper installation, operation (within 1 bar pressure), and basic maintenance, our heavy-wall line is designed for multi-season use. Depending on environmental conditions (UV intensity, water quality, soil), a service life of 3-5 years or more can be expected, providing a significant return on investment compared to replacing thin-wall tapes annually.

Q4: What fittings are compatible with the 16mm (or 12mm) drip line?

A: Our drip line is manufactured to standard industry dimensions. It is fully compatible with all standard 16mm (or 12mm) “barbed” or “grommet” takeoff fittings, connectors, couplers, end plugs, and valves.

Q5: What is your MOQ (Minimum Order Quantity)?

A: Our MOQ depends on the specific product (diameter, flow rate, spacing). As a manufacturer, we primarily service bulk and project orders (e.g., full container or multi-pallet quantities). Please contact our sales team with your requirements for a specific MOQ.

Q6: Can I request a sample for testing?

A: Absolutely. We strongly encourage irrigation engineers, project managers, and farm owners to request samples. We want you to see and feel the heavy-wall construction and dripper quality firsthand. Please use the “Request Sample” button or contact our team.

Q7: What is the lead time for a bulk order (e.g., 40ft container)?
