  • Pipe classifications according to materials

    plumber bondi Pipe classifications according to materialsInstalling a sewer pipe isn’t easy and it’s also one of the costliest pipe restoration methods out there. Pipe restoration contractors know the importance in using the right material for a pipe. There are various classifications of pipes that are used in pipe installations, and each one is composed of different materials. There is no perfect sewer pipe material since each one has its own perks and drawbacks; we’re going to delve more about it in this article.

    Cast iron pipes

    Generally, metallic pipes were a popular type of pipe in the 1970s because it was truly a sturdy material. Cast iron can actually still out level a lot of modern pipes in terms of strength and toughness. The ductile strength was also a disadvantage since it was a bit difficult to cut and integrate by section. In addition, cast iron is just like any other metallic material out there ―— it’s very susceptible to rusting and corrosion. It’s a well-known fact that cast iron can be integrated into a sewer system for long term but the problem is that its corrosion issues dwindle its lifetime easily. Homes that have cast iron pipes in the 1970s-1980s that haven’t been changed since then are having a lot of problems with the plumbing and sewer system due to the cast iron being old and corroded. Cast iron is still being used today but only a few manufacture these materials since it’s obsolete.

    Vitrified clay pipes

    Clay pipes were first introduced for sewage pipelines in the 1880s to the 1970s. The clay pipes that are used today are way on a higher league than its first versions in the past. Specifically, the clay pipes that are used in modern sewer pipeline are called vitrified clay pipes or VCP. These clay pipes are vitrified (i.e. exposed to high temperatures) and cooled down. The heating process causes the clay pipes to become more durable than its previous form. Just like cast iron, VCP takes a lot of time to be installed since it’s heavy and durable. VCP can last longer than most metallic pipes simply because it doesn’t rust and can resist more corrosion-causing chemicals and substances. The only things that are able to heavily damage VCP are highly concentrated caustic chemicals/sewer wastes and hydrofluoric acid.

    Plastic sewer pipes

    There are different types of plastic pipes used in both plumbing and sewer. When it comes to sewer pipes, the commonly used ones are the ABS and PVC. The reason why these are the kinds of plastics used are because it has a very high protection against caustic chemicals and sewer wastes substances. ABS and PVC are commonly used today in pipe installations since it has a long lifespan which is from 50 to 80 years while having high defence against corrosion. The only issue with using plastic sewer pipes is the low tensile strength. Using plastic pipes in areas in which the surrounding surface of the sewage system is exposed to hydraulic pressure may shorten the lifespan of ABS and PVC.
