Our range of HDPE pipes are recommended for their endurance in the field – giving engineers and contractors alike the confidence in specifying a quality brand that meets the highest demands from clients and for different applications.
HDPE Pipe systems are manufactured to, and carry the SABS mark of trusted quality for SANS ISO 4427 and are available in diameters from 16mm up to 110mm.
The high impact strength of HDPE pipes compared with other plastic materials ensures a greater resistance to the rigours of pipe laying conditions.
HDPE pipe has low notch sensitivity, providing a high level of resistance to the effects of external damage which is especially important for pipe bursting operations and other applications where there is a likelihood of such damage.
Because of their light weight and long lengths, HDPE pipe is easy to install. Polyethylene coiled pipes are widely used in applications such as stock watering, irrigation systems, communication, reticulated water mains due to rapid installation and the ease and low frequency of jointing.
HDPE pipes have lower friction factors than most non-plastic materials. The surface energy characteristics of HDPE ensure that material deposition is inhibited and the smooth bore characteristic is maintained over the working life of the pipeline.
HDPE Pipes have a proven high reliability record across a wide range of industries and applications for a period of nearly 50 years. HDPE also provides a long maintenance-free lifetime with low whole life costs, compared to many other materials.
Outstanding resistance to a wide range of chemical reagents allows the use of polyethylene systems in applications such as tailings pipelines and chemical treatment applications used in mining operations.
HDPE pipe is flexible and can be bent to a minimum bending radius of 30 times the pipe’s outside diameter. This flexibility is critical in applications such as submarine pipelines, mine subsidence and earthquake prone areas. The inherent resiliency and flexibility of HDPE pipe allows it to absorb surge pressures, vibration and stresses caused by soil movement.
Excellent abrasion resistance means that HDPE pipes can provide long life in abrasive slurry applications, mostly outlasting other pipe materials such as mild steel and rubber lined steel.
The inclusion of carbon black in the raw material means that HDPE pipes are stabilised against ultra violet (UV) light degradation. Black HDPE pipes are therefore suitable for installation where pipes are exposed to direct sunlight.
