What is replacing cast iron pressure pipe in modern-day construction for gas and water?

Plastic pipe is increasingly used in modern-day construction for gas and water systems due to its numerous advantages over traditional materials like cast iron. One of the primary benefits of plastic pipe is its lightweight nature, which makes it easier and safer to handle during installation. Additionally, plastic pipe exhibits excellent resistance to corrosion, significantly extending its lifespan compared to cast iron, which is prone to rust and degradation over time.

Moreover, plastic piping systems can be installed in a variety of environments without fear of deterioration from moisture or chemicals, making them suitable for both indoor and outdoor applications. The flexibility of plastic pipes also allows for easier routing and installation, adapting to various building designs without requiring extensive fittings.

Furthermore, many plastic pipe materials, such as PVC (polyvinyl chloride) and PE (polyethylene), are also less expensive than traditional materials, providing cost savings in construction. This economic benefit, combined with performance efficiency, has led to the widespread adoption of plastic pipe in plumbing and gas applications, replacing the less efficient cast iron pressure pipe.
