PVC-O PIPES ARE TOUGHER THAN THEIR DUCTILE IRON COMPETITORS IN EXTREME FIELD TESTING - Download Testing Report Here

Triple Field Installation testing

PVC (polyvinyl chloride) pipes and DI (ductile iron) pipes both offer the benefits of relatively high tensile strengths, burst pressures and crushing loads. However our closer look study proven the real strength in the pipes market as PVC-O Pipes.

To demonstrate the superior strength of PVC Pipes a new study used an installation contractor to subject a length of 150 millimetre diameter PN sixteen oriented PVC-O pipe and PN thirty five ductile iron pipe to some extraordinary abuse.

Although pipes would not be subjected to this type of abuse during installation, these tests clearly illustrate the toughness of PVC-O compared to the ductile iron pipe.

TEST ONE - Driven over by 20-tonne excavator Not Once, But Twice!

Although the PVC pipe was severely creased and gouged by the excavator’s tracks, it survived without penetration.

TEST TWO - 250kg Rock Dropped from height of 2.5metres

The PVC pipe sustained only minor surface markings from the impact and had become slightly out of round at the point of impact, demonstrating the amazing resistance to damage that PVC-O has.

The Ductile Iron pipe suffered a gash 100 millimetre long by 10 millimetre wide.

TEST THREE - Pressure testing PVC pipes to identify any splits, tears or weaknesses.

The PVC pipes were filled with water and pressure was applied whilst the PVC-O pipe was monitored for leaks. As the handle was pumped, the pressure progressively increased expanding the pipe and returning it closer to its original circular shape until the pressure reached 1600 kilopascals, the working pressure rating for this PVC-O pipe.
