Differences Between uPVC, CPVC, and PEX Pipes

When choosing the plumbing system, picking the right type of pipes and fittings system is essential for ensuring the efficiency and safety of your system. For both residential and commercial plumbing, the three most common types of pipes used are uPVC, CPVC, and PEX. Before deciding on a material to use for a project, it’s crucial to understand the distinctions between them.

uPVC Pipes

uPVC, or Unplasticised polyvinyl chloride, is a durable, lightweight, and non-toxic material used for plumbing pipes. It is a popular choice in residential and commercial plumbing due to its ability to handle high water pressure, its resistance to corrosion, and its affordability.

uPVC is more rigid, and durable, making it a popular choice for outdoor applications.

Why uPVC?

  • Affordable and easy to install
  • Highly resistant to corrosion and chemical damage
  • Can handle high water pressure

CPVC Pipes

With a maximum service temperature of 93°C, Astral pipes provide exceptional impact resistance without compromising their pressure-bearing capacity, tensile strength, or Vicat softening temperature. This means that they can withstand a wide range of demanding conditions without sacrificing performance or durability. These properties make them an ideal choice for hot water systems, industrial applications, and fire sprinkler systems.

Understanding the difference between CPVC and uPVC

When it comes to plumbing, CPVC is the more heat-resistant and chemically resistant option compared to uPVC, which is more affordable. CPVC is ideal for hot water systems and industrial applications, while uPVC is commonly used in cold water systems and drainage applications.

Difference between PVC and uPVC

PVC and uPVC are both types of plastic used in plumbing. PVC is a more flexible and affordable option, but not suitable for hot water systems. uPVC, on the other hand, is more rigid, and durable, making it a popular choice for outdoor applications.
