Plumbing Piping: Knowing your Options

As you plan your next plumbing project, it is important to assess the different kinds of pipe for the job. While you could use stainless steel and brass tubing, the majority of projects are completed with galvanized metal, some plastic pipes, o r copper tubing. Whether you prefer to purchase from surplus pipe suppliers or directly from manufacturers, you want to know your options out there.

Metal Pipes

Historically, most piping was manufactured from brass, cast iron, copper or other metals. Copper and brass have an innate resistance to corrosion, making them great choices. However, pipes made from these metals can start to age over time, usually because of the lead in the solder used for connecting them. That is why many industries prefer to use steel. This metal offers exceptional strength, durability, and toughness. It is a versatile and cost-effective option for sewer and water plumbing and pipeline systems.

Galvanized and Black Steel Pipes

The galvanized form of steel pipes features a protective zinc coating which helps in preventing rust, corrosion, and mineral deposit buildup, prolonging the lifespan of the pipe.  Also, these pipes can achieve rust-free protection for up to thirty days while maintaining comparable strength when the surface is applied with a durable coating.

Meanwhile, black steel pipe has a dark-colored iron oxide coating on the entire surface. It is used for applications which don’t require galvanized protection. This pipe is mainly used to transport water and gas in rural and urban areas as well as to deliver high-pressure steam and air. It is common to see these pipes in fire sprinkler systems because of its high resistance to heat.

304 Stainless Steel Pipe

This is another type of pipe that can be used for transporting liquid. Stainless steel provides high resistance to corrosion, high strength-to-weight ratio, superior durability, resistance to electrical and thermal conductivity, ease of cleaning, and ease of fabrication. Also, black steel pipes are used for other water transfer applications such as gas lines and potable water from wells.

Brass Tube/Pipe

While brass piping is an older material, many industries and projects still use it today for water supply and drain lines as well as gas lines. With its high resistance to corrosion, brass piping can be used while ensuring safe drinking water. This is also possible if the brass is free of lead. Brass is a fairly soft metal so brass tube or pipes should be installed with a tight seal to prevent leaks.
