Description

HDPE Black Pipe PE100 SDR11 PN16 – 1.5m Lengths

Our HDPE Black Pipe range delivers the performance of full-specification PE100 SDR11 pressure pipe in practical 1.5m cut lengths. Each pipe is manufactured from virgin PE100 grade high-density polyethylene to AS/NZS 4130, with a pressure rating of PN16 (16 bar at 20 degrees Celsius) and a Standard Dimension Ratio of 11.

These 1.5m lengths are cut from certified 6m trade lengths and are ideal for smaller projects, repairs, fabrication, and applications where full-length pipe is impractical. The shorter length also makes them easier to handle on site and more economical to ship via standard courier and freight services.

HDPE PE100 pipe offers significant advantages over traditional metallic piping. It is completely corrosion-resistant, lightweight, and flexible enough to accommodate ground movement without fracturing. The carbon black content provides excellent long-term UV stability for above-ground installations, while the smooth internal bore minimises friction losses and resists biological fouling.

Available Sizes

110mm OD x 10.0mm wall
125mm OD x 11.4mm wall
160mm OD x 14.6mm wall

Applications

Potable water supply and reticulation
Irrigation and agricultural water systems
Gas distribution pipelines
Mining and slurry transport
Industrial process piping
Stormwater drainage and sewer rising mains
Marine and wharf infrastructure
Chemical and effluent transfer lines
Fabrication and pipe fittings manufacture
Short-run repairs and maintenance

Joining Methods

HDPE PE100 pipe can be joined using butt fusion welding, electrofusion welding, or mechanical compression fittings. The SDR11 wall provides ample material for reliable fusion joints. For smaller diameters, metric compression fittings offer a quick and reusable connection method without the need for specialised welding equipment.

Frequently Asked Questions

What is HDPE PE100 SDR11 PN16 pipe?

HDPE PE100 SDR11 PN16 pipe is a high-density polyethylene pressure pipe manufactured to AS/NZS 4130. PE100 refers to the material grade (minimum required strength 10 MPa), SDR11 is the standard dimension ratio (wall thickness relative to diameter), and PN16 indicates a maximum operating pressure rating of 16 bar (1600 kPa) at 20 degrees Celsius.

What are common applications for HDPE PE100 pipe?

HDPE PE100 pipes are widely used for potable water supply, irrigation, gas distribution, mining slurry lines, industrial process piping, and stormwater drainage. Their flexibility and corrosion resistance make them suitable for both above-ground and below-ground installations.

Can HDPE pipe be used for drinking water?

Yes. PE100 pipe manufactured to AS/NZS 4130 with appropriate WaterMark certification is approved for potable water applications in Australia. Always verify the pipe carries the correct certification for your project.

How is HDPE pipe joined?

HDPE pipe can be joined using butt fusion welding, electrofusion welding, or mechanical compression fittings. Butt fusion is the most common method for larger diameters, while compression fittings are often used for smaller sizes and repairs.

What is the temperature range for HDPE pipe?

HDPE PE100 pipe is rated for continuous service from -40 degrees Celsius to +60 degrees Celsius. The PN16 pressure rating applies at 20 degrees Celsius and must be de-rated for higher operating temperatures.

Is HDPE pipe UV resistant?

HDPE pipe containing carbon black (black pipe) has excellent UV resistance and can be used in exposed above-ground installations. The carbon black content of approximately 2-2.5% provides long-term protection against ultraviolet degradation.

Why are these pipes sold in 1.5m lengths?

Our 1.5m lengths are ideal for smaller projects, repairs, fabrication work, and customers who do not require full 6m trade lengths. They are easier to handle, transport, and store, and can be shipped via standard freight services.

What wall thickness does SDR11 pipe have?

SDR11 means the outside diameter is 11 times the minimum wall thickness. For example, 50mm pipe has a 4.6mm wall, 90mm pipe has an 8.2mm wall, and 160mm pipe has a 14.6mm wall.

Can HDPE pipe be bent?

Yes. HDPE pipe can be cold-bent to a minimum radius of approximately 20 to 25 times the outside diameter, depending on the SDR. This flexibility reduces the need for fittings in many installations.

Is HDPE pipe resistant to chemicals and corrosion?

HDPE is highly resistant to a wide range of chemicals including acids, alkalis, and salts. Unlike metal pipes, it will not corrode, scale, or suffer from galvanic or electrolytic attack, making it an excellent choice for aggressive soil conditions and chemical transport.
