The copper pipe is one of the most recognisable pieces of equipment in plumbing and construction. Sometimes, however, it is replaced by cheaper and more easily-available plastic or other synthetic material. These alternatives do not have the same safety and sustainability advantages as copper.
Disadvantages of plastics and synthetics
In a world that is increasingly aware of environmental issues, the push to reduce our plastic use has intensified. From the production process using non-renewable resources such as oil to the lack of biodegradability, the problems with plastic are well-documented.
Synthetic furnishings are also considerably more flammable than natural alternatives. and can release significant amounts of toxic chemicals when burned. This can lead to long-term health problems, including cancer, for firefighters involved in major incidents such as the blaze at Grenfell Tower.
Advantages of copper
PVC melts at only 421°C. The melting point of copper is 1085°C. It is clear which is safer in any residential or commercial building during a fire. That is not the only way that copper is used in fire safety. In powdered form, it is added to some types of fire extinguishers to absorb heat, slow combustion, remove oxygen and even prevent relighting in conflagrations involving flammable metals.
Sprinkler systems cannot afford to be blocked when there is a fire that needs to be fought. Copper has antimicrobial properties which help prevent the growth of dangerous moulds and fungi in pipes. This keeps water clean for human use and again improves fire safety.
Copper is a versatile material, as can be seen in catalogues such as at https://watkinspowis.co.uk/products/copper-pipe-fittings-and-press-systems/. It can easily be shaped and adapted to a variety of situations without losing strength and durability.
When copper is no longer useful, it can be recycled an infinite number of times rather than contributing to landfill. It is also less susceptible to corrosion than steel, another important consideration when choosing pipe material
There are numerous advantages to using copper instead of plastic or synthetics in pipework, particularly in sprinkler systems. It improves fire safety whilst also being the more environmentally sustainable option.
