Which of the following is the advantage of cast iron pipes?
Which of the following is the advantage of cast iron pipes? d) They are resistant to corrosion. Explanation: The cast iron pipes are subjected to tuberculation which reduces their carrying capacity, they are fragile, heavier, resulting in more cost when their diameter exceeds 120cm and they are resistant to corrosion.
What is the life expectancy of cast iron pipe?
between 50 and 100 years
Deterioration of cast iron pipes is normal after just 25 years. Wear and tear is normal in residential pipe systems. One frequently asked question is “How long do cast iron drain pipes last?” Cast iron waste pipes last anywhere between 50 and 100 years.
