50mm SDR11 Poly Pipe for Irrigation

What is a 50mm SDR11 Poly Pipe?

The 50mm poly pipe refers to a polyethylene pipe with an outside diameter of 50mm. When classified as SDR11, it means the pipe has a wall thickness to diameter ratio of 11, providing higher pressure resistance than other SDR classes like SDR17 or SDR21. This makes SDR11 poly pipe suitable for medium to high-pressure water supply, ideal for irrigation, landscaping, or even industrial applications.

Why Choose SDR11 Poly Pipe for Irrigation?

Here are some key reasons why a 50mm SDR11 pipe is a preferred choice for irrigation projects:

High Pressure Rating

SDR11 pipes typically withstand pressures up to 16 bar (230 psi), making them suitable for pump-driven irrigation systems or long-distance water conveyance.

Durability

Made from high-density polyethylene (HDPE), these pipes are UV-resistant, corrosion-free, and have a long service life, often exceeding 50 years in buried conditions.

Flexibility and Easy Installation

Poly pipes are flexible and lightweight, which reduces the need for excessive fittings and simplifies installation—especially useful in uneven terrain or large-scale fields.

Compatibility with Fusion Fittings

SDR11 poly pipes can be easily connected using butt fusion or electrofusion fittings, creating strong, leak-free joints.

Common Applications in Irrigation

Drip irrigation systems in farms and orchards

Sprinkler systems for lawns, golf courses, and parks

Greenhouse watering systems

Irrigation mainlines and sublines in horticulture or row crops

Whether you are a farm manager or landscape contractor, using 50mm SDR11 poly pipe for irrigation helps reduce water waste and operational costs.

FAQ

1. What does SDR11 mean in poly pipe?

SDR11 stands for "Standard Dimension Ratio 11", meaning the pipe's outside diameter is 11 times its wall thickness. SDR11 poly pipe has a thicker wall and higher pressure rating compared to SDR13.6 or SDR17, making it suitable for pressurized irrigation systems.

2. Is 50mm poly pipe suitable for irrigation?

Yes, 50mm poly pipe is a common size for small to medium-scale irrigation systems. It offers a good balance between flow capacity and ease of handling, especially for drip and sprinkler irrigation.

3. Can SDR11 poly pipe be buried underground?

Absolutely. SDR11 HDPE pipes are designed for underground use. They are resistant to corrosion, chemicals, and UV, and can last for decades when properly installed.

4. What is the pressure rating of 50mm SDR11 pipe?

Typically, 50mm SDR11 HDPE pipe has a pressure rating of 16 bar (approximately 230 psi), depending on the manufacturer and standard (e.g., ISO, AS/NZS, or ASTM).

5. How do I connect 50mm SDR11 poly pipes?

These pipes are usually joined by butt fusion welding, electrofusion fittings, or compression fittings, depending on the application and installation environment.

6. Where can I buy 50mm SDR11 poly pipe near me?
