One of the greatest features of HDPE pipes is the fact that a wide variety of jointing systems is available to suit a whole range of applications. The jointing systems can be divided into permanent jointing and detachable jointing.
The schematic below illustrates the available systems.

Advances of HDPE material

Considerable strides have been made in improving the quality of HDPE material and its long term ability to withstand pressure. The current SABS specification, SANS 4427, covers 3 different material grades (PE 63, PE 80 and PE 100). These three material grades have different properties which enable them to be classified with minimum required strengths (MRS) of 6.3 MPa, 8,0 MPa and 10.0 MPa respectively. Applying a design coefficient of 1.25 (safety factor) to the MRS gives the design stress used by SANS 4427 for these materials (5.0 MPa, 6.3 MPa and 8.0 MPa respectively) with the result that the wall thickness for a particular size and class becomes progressively less as the change is made to a material with a higher MRS.


Aubert Pipe & Profile solutions have for several years been confidently supplying their range of HDPE pipes, fittings and saddles for successful use in a variety of applications in the Civil, Agricultural, Municipal, Mining and Industrial sectors. Because of the good chemical resistance and abrasion resistance properties they are also extensively used in chemical, waste and slurry applications.
