The Benefits Of PVC Pipes Used in Piping Systems

1. Why PVC pipes?

PVC pipes are used in a wide variety of piping applications, from transportation of drinking water to urban farming. This popularity owes to their key properties: safe, durable, cost-efficient and sustainable.

 

2. PVC pipes are safe

Clean water stands as one of Earth's most invaluable resources. PVC water pipes play a crucial role in preserving the quality of drinking water, thanks to their exceptional inertness and resistance to corrosion, even when exposed to chlorinated disinfectants. This resistance ensures that PVC pipes remain free from bio-film contamination, which can otherwise serve as a breeding ground for bacteria.

 

Moreover, PVC water pipes and fittings minimise unnecessary water loss from the source to the consumer, thereby enhancing water conservation. By facilitating access to clean water, PVC pipes make a significant contribution to achieving Sustainable Development.

 

PVC in itself is inert and non-toxic, and recognised as a Polymer of Low Concern by the OECD. Because it is used below its glass transition temperature (80°C), PVC can be considered as a functional barrier preventing any low molecular weight substances to migrate to drinking water. Peer-reviewed research demonstrate migration levels far below the detection limit of the most modern analytical techniques.

 

PVC pipe manufacturers are subject to third-party certification by accredited laboratories and institutes, who subsequently also carry out regular audits to ensure continued compliance.

3. PVC vs. copper: Corrosion and bacterial growth

Some tout traditional materials such as copper as safer than PVC pipes. Yet research reveal that copper is vulnerable to corrosion, resulting in various health problems. Copper pipes are more prone to the growth of Legionella bacteria, which can cause Legionnaire's disease, compared to PVC pipes. Additionally, the leaching of copper into drinking water has been linked to structural failure and gastrointestinal issues.

 

4. PVC pipes are fire safe

In addition to their exceptional performance in maintaining water quality, PVC pipes also exhibit notable fire safety characteristics. PVC is inherently flame retardant due to its high chlorine content of 57%, meaning it is less likely to ignite and contribute to the spread of fire. Further, PVC is comparable to most commercial materials in terms of smoke toxicity and does not pose a greater risk of fume generation during fires than other organic polymers.

 

5. Why Pvc Pipes Safety

The chlor-alkali industry, integral to modern society, involves a process where table salt is split into caustic soda and chlorine. This industry underpins numerous sectors: caustic soda is crucial for producing alumina and paper, and is essential in water treatment, drinking water purification, cleaning agents, pharmaceuticals, and food processing.

 

About 30% of the chlorine goes into PVC production. The majority of chlorine aids in water disinfection, manufacturing of around 80% of all pharmaceuticals, and the creation of products ranging from electric car batteries to solar panels and firefighter face shields in polycarbonate (PC). It is important to note that many chemicals, plastics, and medicines use chlorine at some stage in the manufacturing process, although the end product is chlorine free.

 

6. PVC pipes are durable

Durability is key to utility companies and consumers. The first PVC piping systems were installed over 80 years and most of these are still in use. Dig up studies show minimum of degradation and confirm that the pipes have many more years of service left. The expected lifespan of a PVC pipe is 100 years or more for underground pipes. Moreover, PVC pipes consistently show a much lower failure rate than non-plastic materials such as ductile iron, steel, asbestos cement, and cast iron.
