Applications

Some typical applications of HDPE pipe include the following:

• Mining (surface and underground)
• Water supply
• Agriculture / irrigation
• High temperature liquids and gases – usually not above 60°C
• Corrosive water and effluents
• Dewatering
• Drainage and sub-soil drainage
• Protection of electrical and telephone cables
• Hydraulic transport
• Pipeline rehabilitation

Jointing methods

HDPE allows for a range of jointing systems to suit various applications. Permanent and detachable
jointing methods are used, with several options available under each method;

Over the past several years, the use of dual wall HDPE corrugated pipes for storm water has increased dramatically. This is because of their strength, durability, joint integrity and long-term cost-effectiveness. HDPE double wall pipes are well proven in some of the world’s toughest environments.  Results show that forward-thinking municipalities realize the future of storm water management relies on the best technology. HDPE corrugated pipes are manufactured from the highest quality materials and are the most technologically advanced product available for moving storm water and wastewater.  The pipes have two layers; the outer layer is corrugated to enhance the pipe’s stiffness while reducing weight and cost; while the inner layer is smooth to improve flow efficiency and lower operational costs.
HDPE corrugated pipes can replace other piping material such as concrete, GRP and clay pipes as well as traditional pipes.
