Comparison Between Metal Pipes and UPVC Pipes

Metal pipes or uPVC pipes, this debate has long been running, leaving many uncertain about which plumbing solution to choose. While both options have their benefits, uPVC pipes have become a preferred choice today, as they were designed specifically to address the drawbacks of metal pipes. 

With superior corrosion resistance and a lead-free design, uPVC pipes and fittings offer benefits that metal water pipes simply can’t match. However, some professionals remain sceptical, preferring traditional options. This blog compares uPVC pipes vs metal pipes from scratch, helping you understand the fundamental differences in these plumbing pipes and make an informed choice. 

What are Metal Pipes?

Metal water pipes, made from steel, copper, and cast iron, have been used for decades in various plumbing applications. Their high strength makes them suitable for transporting fluids, and gases, and handling drinking water systems in all conditions. However, metal pipes for plumbing are prone to corrosion and are heavy and expensive. Even its maintenance is hefty, due to its susceptibility to rust which calls for constant repairs.

What are uPVC Pipes? 

UPVC pipes are upgraded versions of PVC pipes but without any plasticisers. They are rigid, durable, and used in various plumbing applications, from drainage to drinking water supply. It is a major alternative to metal pipes, uPVC stands out for its lightweight nature, cost-effectiveness, and long lifespan. 

Unlike traditional pipes, uPVC does not rust, corrode, or react with water, making it ideal for transporting potable water and industrial fluids. Its non-toxic composition and smooth inner surface prevent scaling and bacterial growth, ensuring a safe, hygienic, and efficient piping system.

UPVC Pipes vs Metal Pipes

Here’s a comparison table to help you better understand the key differences in features between these plumbing pipes:

Criteria

UPVC Pipes

Metal Pipes

Noise Resistance Reduced water flow noise due to smooth surface Prone to generating noise due to rigid structure
Resistance to Freezing Does not crack easily under freezing conditions Can expand or crack under freezing conditions
Chemical Resistance Highly resistant to most chemicals and solvents Susceptible to chemical reactions that may weaken the pipe
Installation Tools It needs minimal tools and is easy to cut and join Requires specialised tools, fittings, and welding for joints
Aesthetic Appearance Uniform, clean appearance, often white or cream-coloured May develop discoloration or stains over time
Health and Safety Non-toxic; safe for potable water transport Potential health risks from lead or rust
Lifespan Lasts 50+ years with proper installation and care Variable lifespan, depending on the type of metal
Environmental Impact Recyclable; lower energy production requirements Recyclable, but higher energy consumption during production
