• Abrasion of the inner wall of the pipes is very low
• Resistant to acids and other aggressive fluids
• Corma’s Double Layer InLine Couplings ensure lowest tolerances to guarantee long-lasting joint tightness
• High flow rate, low Manning’s Coefficient
• Strength is derived from corrugated design of the outer wall
• Save up to 60 % in raw materials vs. solid walled plastic pipes
• Low weight means less labour for installation
• Can be installed in constrained areas
• Corma’s Double Layer Inline Coupling low tolerance design provides a tight joint that won’t leak
• Fewer joints in 6m pipes (three times longer than conventional piping systems), creating fewer opportunities for leaks
• Lower transportation costs: More double wall corrugated pipe can be loaded on one truck vs. concrete pipes
• Less damage during storage and handling
• No heavy-duty equipment required for installation
• Corrugated piping systems easily withstand natural settlements without suffering cracks or leakages
• Flexibility means safety – plastic corrugated pipes are engineered to bend without compromising the structural strength, unlike pipes made of rigid materials that are prone to cracking
• Less raw material consumption compared to solid wall plastic pipes
• Recyclable at the end of its life cycle
• CO2 emission for concrete pipes is 3-4 times higher than for double walled corrugated plastic pipes
