560 mm HDPE Pipe
Catalogue specifications for 560 mm polyethylene pipe.
Published
560 mm HDPE pipe means pipe with a 560 mm outside diameter. That figure alone does not define an order — at this diameter the factory produces 9 different pressure classes, which differ in wall thickness and therefore in bore, weight and price. What completes an order is the diameter plus the SDR and the material grade.
At 560 mm, wall thickness ranges from 11 to 62.5 mm and nominal pressure from 2.5 to 20 bar, depending on the SDR and on whether the material is PE80 or PE100.

| SDR 11 | Wall thickness 50.8 mm — nominal pressure 12.5 bar in PE80, 16 bar in PE100 |
| SDR 9 | Wall thickness 62.5 mm — nominal pressure 16 bar in PE80, 20 bar in PE100 |
Figures from the factory catalogue (DIN 8074 / ISO 4427-2). A lower SDR means a thicker wall, a higher pressure rating and a smaller bore.
The nominal pressure figure applies at 20 °C. If the line runs warmer, the real allowable pressure is lower and has to be calculated with the temperature derating factor.

What to state when ordering

FAQ
- What wall thickness does 560 mm HDPE pipe have?
- It depends on the pressure class. At 560 mm the catalogue offers 9 classes, from SDR 51 at 11 mm to SDR 9 at 62.5 mm. Without an SDR, the wall thickness is undefined.
- What is the pressure rating of 560 mm pipe?
- From 2.5 to 20 bar, depending on the SDR and material grade. Those figures apply at 20 °C; above that they must be corrected with the temperature derating factor.
- Is 560 mm supplied in coils or straight lengths?
- In 12 m straight lengths; at this wall thickness the pipe cannot be coiled.
- How is 560 mm HDPE pipe priced?
- By weight, not by the metre. Weight per metre follows from diameter, wall thickness and material density — which is why 560 mm costs differently in each SDR. Quote the diameter, SDR and quantity to get a current price.
