uPVC Pipe Properties
Features of uPVC Pipes as per ASTM standard.
Corrosion Resistance
uPVC pipes are highly resistant to corrosion caused by water and various chemicals, ensuring long-term durability and minimal maintenance requirements.
Smooth Interior Surface
The smooth interior surface promotes efficient water flow, reducing friction and pressure loss. It also prevents the accumulation of sediment and scale, minimising the risk of clogs and blockages.
Lightweight
uPVC pipes are lightweight, making them easy to handle, transport and install — simplifying the installation process and reducing labour costs.
Chemical Resistance
uPVC pipes exhibit good resistance to a wide range of chemicals, making them suitable for diverse applications that involve different fluids and substances.
Easy Installation
uPVC pipes can be easily cut, joined and installed using solvent cementing techniques. Their simplicity and versatility during installation save time and effort.
Longevity
uPVC pipes have a long service life due to their resistance to corrosion, chemical degradation and environmental factors, ensuring a reliable and durable plumbing system.
Line Marked on Pipe Lengthwise
Why the line on uPVC pipe matters.
Every Signet uPVC pipe carries a line marked along its length. This line serves five important purposes during installation and inspection.
Alignment
The line helps ensure the correct alignment of the pipe during installation. It provides a visual reference to ensure the pipe is properly aligned with other pipes, fittings or fixtures.
Straightness
The line helps check the straightness of the pipe. It allows installers to assess if the pipe is perfectly straight or if it has any bends or deviations that could affect performance.
Measurement
The line marked on the pipe can be used as a measurement reference, aiding in accurately determining the length of the pipe for proper fitting and joining.
Visual Inspection
The line acts as a visual indicator for inspectors and maintenance personnel, allowing them to identify any potential issues or damages such as cracks, breaks or deformations.
Orientation
The line helps indicate the proper orientation of the pipe, ensuring it is installed with the correct side up or facing the desired direction — especially important where specific flow directions are required.
uPVC vs Metal Pipes
Why uPVC is the ideal choice over metal.
uPVC consistently outperforms galvanised steel and other metal pipes across the properties that matter most for water supply systems.
Corrosion Resistance
Unlike metal pipes, uPVC pipes are not susceptible to rust, scale or chemical corrosion from water and other substances — reliable even in environments with aggressive water conditions.
Smooth Interior Surface
uPVC pipes maintain their smooth interior surface over their full service life. Metal pipes accumulate sediment, scale and rust over time, reducing flow and increasing the risk of blockages.
Leak-proof and Water-tight
Joints in uPVC pipes can be securely connected using solvent cement, ensuring a leak-proof, water-tight system that eliminates the risk of water damage to building structures.
Lightweight and Easy Installation
Significantly lighter than metal pipes — uPVC is easier to handle and install, reducing labour and installation costs. Quick to cut, join and fit in new builds and retrofit projects alike.
Thermal Insulation
uPVC pipes exhibit excellent thermal insulation properties, helping maintain the temperature of the water being transported and reducing heat loss in plumbing runs.
Cost-effectiveness
uPVC pipes are more affordable, have lower installation costs and require minimal maintenance. Their longevity contributes to long-term cost savings compared to metal pipe systems.
Lead-Free uPVC Pipes & Fittings
Safe water transportation to ASTM standard.
Signet's lead-free uPVC pipes and fittings are designed for safe and reliable water supply systems — available in sizes ranging from ½ inch to 4 inches, catering to all bathroom and building plumbing requirements.
