Why Choose Polyethylene Pipes for Water Supply Systems
Introduction
Water supply systems are vital for modern infrastructure, ensuring clean and safe drinking water. Polyethylene pipes stand out as the material of choice for this purpose. Let’s dive in and explore why you should select polyethylene pipes for water systems.
Advantages of Polyethylene Pipes
Polyethylene pipes have a range of advantages over other pipe materials that make them perfect for water supply systems.
Lightweight and Easy to Handle: Polyethylene pipes are significantly lighter than other traditional pipe materials like steel and copper, which makes them easier to transport and handle, reducing labour costs.
Excellent Durability: Polyethylene pipes are known for their durability and ability to withstand harsh environmental conditions. They are resistant to cracking and leaking, which reduces the chances of leaking in the systems.
Corrosion Resistance: Polyethylene pipes are highly resistant to chemicals and other corrosive substances or materials. Unlike metal pipes, polyethylene pipes don’t rust over time, ensuring long-term integrity in water supply systems.
Flexibility and Ease of Installation: Polyethylene pipes are very flexible and can be bent and shaped to fit the landscape's contours, even without specialised fittings. Obstacles in the terrain can be avoided which simplifies installation.
Leak Free: PE can provide a leak free pipe system, that is easier and safer to install as it doesn’t require people down in trenches and is flexible, lasts longer, doesn’t corrode, is recyclable, easily repairable and over its life the least expensive option for the majority of installations.
Why use anything else?
Durability in Water Supply
Water supply systems are expected to reliably deliver clean and safe drinking water for decades without succumbing to wear, degradation, or frequent maintenance. That’s why durability in water supply is a crucial factor when choosing pipe material. Polyethylene pipes excel in durability and long-term performance, offering several advantages over other materials.
Unlike steel pipes, PE pipes resist corrosive substances and chemicals, and don’t rust or corrode over time. They also resist environmental factors, such as ground movement, UV radiation, and abrasive material in the soil, reducing cracks and leaks in the pipes. Due to their smooth inner surfaces, biological growth and mineral scaling that accumulate in lines rarely occurs with polyethylene pipes.
Corrosion Resistance
Corrosion is a critical issue in water supply as it will contaminate and reduce water quality, affecting the taste and smell of the water and even leading to health concerns if toxic chemicals leach into the water. Fortunately, polyethylene pipes are widely known for their corrosion and chemical resistance, ensuring safe water at all times.
All polyethylene pipes are inherently corrosion-resistant. They don’t react with water, oxygen, or ions in the same way steel pipes do. Due to this, there is no chance of rusting when it comes to polyethylene pipes. They are also highly resistant to various chemicals, including those that are commonly found in drinking water. Moreover, polyethylene pipes can achieve these feats without needing protective coatings or linings, simplifying installation, maintenance and reducing costs.
Polyethylene pipes pass various industry standards and certifications that testify to their corrosion resistance. They pass standards like ISO 4427, which is an international standard that outlines the requirements for polyethylene pipes used in the conveyance of water for human consumption, and NSF/ANSI 61—a certification that ensures that the materials used in drinking water systems do not leach harmful contaminants into the water.
These standards and certifications assure that polyethylene pipes meet rigorous quality and safety requirements. This makes them the ideal choice for water supply systems where ensuring high water quality and long-term durability are crucial.
FAQ
-
Absolutely. Polyethylene pipes shine in their versatility, fitting comfortably into underground and above-ground water supply scenarios. Their corrosion resistance and ability to hold up against soil shifts make them a top choice for underground water distribution, sewage, and gas pipelines. Meanwhile, their flexibility stands them in good stead for above-ground use, especially in outdoor settings like agricultural irrigation, without extra protective measures.
-
It's all about the long game. Initially, polyethylene pipes may or may not seem more affordable per metre than metal (steel or copper) or PVC counterparts. But the actual savings emerge over time. Due to their corrosion resistance and longevity, polyethylene pipes demand far less maintenance and replacements, translating to substantial cost savings in the long run. Plus, their insulative properties minimise heat loss in hot water supply systems, offering potential energy savings.
-
They certainly are. Whether braving winter's chill or enduring summer's heat, polyethylene pipes remain steadfast. They stay flexible in freezing conditions without succumbing to brittleness or cracks. In hotter climes, they resist UV radiation admirably, ensuring they don't degrade even with extended sun exposure. However, it's always a good idea to adhere to proper installation guidelines, including allowances for expansion and contraction with ambient temperature shifts, to ensure the pipes' longevity. In particularly challenging environments, insulation can be an added safeguard against temperature-induced concerns.
