High density polyethylene (HDPE) pipe is a widely used solution for water supply, gas distribution, agricultural irrigation, and industrial piping systems. Known for its durability, corrosion resistance, and flexibility, HDPE pipe—especially the PE100 SDR 11 type—meets the performance demands of high-pressure systems. When combined with matching HDPE pipe fittings like poly pipe elbows, it forms a robust and long-lasting pipeline network.
In this article, we’ll explore the features and advantages of PE100 SDR 11 HDPE pipes, the role of fittings and elbows, and how to select the right components for your piping projects.
What Is PE100 SDR 11?
PE100 refers to the material grade of HDPE, representing high strength and high density. It’s ideal for pressure piping systems. SDR (Standard Dimension Ratio) is a critical design factor for HDPE pipes. SDR 11 means that the pipe's outside diameter is 11 times the wall thickness, resulting in a thicker wall and higher pressure rating.
PE100 SDR 11 pipes are commonly used for potable water, industrial liquids, and gas transport.
The typical pressure rating for SDR 11 is 16 bar (PN16) for water at 20°C.
These pipes have excellent resistance to UV, chemicals, and abrasion.
HDPE Pipes and Fittings Overview
A reliable HDPE piping system is incomplete without compatible fittings. HDPE pipes and fittings are designed to work together to ensure leak-free and strong joints in various configurations.
Common HDPE fittings include:
Tees (equal or reducing)
Reducers
Flange adapters
End caps
Couplers (butt fusion, electrofusion)
Connection Methods:
Butt fusion welding: for permanent joints with same-diameter pipes
Electrofusion: commonly used for gas and water applications
Mechanical fittings: for temporary or field repairs
Poly Pipe Elbows: Applications and Installation
Poly pipe elbows are essential for changing the direction of a pipeline without stressing the pipe. These elbows are available in various angles, the most common being 90-degree and 45-degree bends.
Applications:
Underground water pipelines
Agricultural irrigation systems
Gas distribution networks
Industrial liquid handling
Advantages:
High impact resistance
Smooth inner surface for better flow
Long service life (50+ years under normal conditions)
Easy to weld or fuse with HDPE pipes
Installation Tips:
Ensure the elbow and pipe are made from the same material grade (e.g., PE100)
Clean and align surfaces before welding
Follow proper cooling and pressure guidelines for fusion joints
Why Choose PE100 SDR 11 HDPE Pipes and Fittings?
Durability: Resistant to corrosion, scale, and biological growth
Flexibility: Ideal for seismic zones or uneven terrain
Pressure resistance: Suitable for high-pressure systems
Lightweight and easy to install: Lower transportation and labor costs

FAQ
Q1: What does PE100 SDR 11 mean in HDPE pipes?
A: PE100 is a high-density polyethylene material grade with excellent strength and durability. SDR 11 refers to the Standard Dimension Ratio, where the pipe's outer diameter is 11 times its wall thickness. This indicates a thicker wall and higher pressure rating, typically PN16 (16 bar) at 20°C.
Q2: What are the advantages of using HDPE pipes and fittings?
A: HDPE pipes offer corrosion resistance, long service life (50+ years), flexibility, and leak-free fusion joints. They are lightweight, easy to install, and suitable for a wide range of applications such as water supply, gas distribution, and agricultural irrigation.
Q3: What is a poly pipe elbow and when is it used?
A: A poly pipe elbow is a type of HDPE pipe fitting used to change the direction of flow in a pipeline. Common angles include 90° and 45°, used in both underground and above-ground piping systems where directional changes are needed.
Q4: How are HDPE pipes and poly pipe fittings connected?
A: The main connection methods include:
Butt fusion welding
Electrofusion welding
Mechanical compression fittings
Each method ensures strong, leak-free joints. Electrofusion is preferred in gas and potable water systems due to its reliability and ease of use.
Q5: Can I use PE100 SDR 11 HDPE pipes for drinking water?
A: Yes. PE100 SDR 11 HDPE pipes are certified for potable water use in most regions. They are non-toxic, resistant to chemical leaching, and maintain water quality over long-term service.
Q6: Are HDPE pipe elbows available in different sizes?
A: Yes. Poly pipe elbows are available in a wide range of diameters, typically matching standard HDPE pipe sizes (e.g., 20mm to 630mm or larger). Elbows are also offered in various SDR ratings to match your pipe wall thickness.
Q7: Where can I buy HDPE PE100 SDR 11 pipes and fittings?
A: You can purchase HDPE pipes and fittings—including poly pipe elbows—directly from manufacturers or suppliers specializing in polyethylene piping systems. For bulk orders or custom sizes, it’s best to contact the supplier directly for specifications and pricing.
