Less conductive I would say.
These days PVC pipes are faster and easier to fit and in many ways more efficient than cast iron.
Because modern PVC and PEX pipes are much more efficient and easier to work with.
Iron pipes are made of iron.
Iron pipes are made of iron.
Pipes are no longer made from iron because iron is prone to corrosion and rusting, which can contaminate water and reduce the lifespan of the pipe. Instead, pipes are now commonly made from materials like copper, PVC, or stainless steel, which are more resistant to corrosion and offer longer-lasting performance.
Copper, iron, and lead are commonly used in construction for pipes and electrical wiring because they are good conductors of electricity and heat, resistant to corrosion, and readily available. Zinc and magnesium are not as commonly used due to their lower conductivity, higher reactivity, and susceptibility to corrosion over time in certain conditions.
Bags of magnesium are attached to iron pipes to prevent corrosion of the pipes. The magnesium acts as a sacrificial anode, meaning it corrodes instead of the iron pipe, thereby protecting the pipe from rusting and extending its lifespan. This process is known as cathodic protection.
Steam carrying pipes
Iron rusts easily when combined with water, and drain pipes have water flowing through them. If iron was used, the pipes would rust within a few days.
galvanized water lines, cast iron drain lines, sometimes lead pipes, terracotta or clay pipes, and in rare cases wooden pipes.
Copper and iron are related as both are metallic elements that are commonly used in various industries. They are both essential for the production of goods and materials, such as wiring, pipes, and machinery. Additionally, both copper and iron can be found in nature as ores and are mined for extraction.
