Evaluating Steel Pipe Versus Plastic Pipe Materials, Part 2

steel pipe plastic materials

In part one of this two-part blog series, we went over some of the basic differences between steel pipe and various plastic pipe materials available today. These are the two most viable options for various piping needs, whether in specific plumbing or related fields.

At Wasatch Steel, we offer a wide selection of steel pipe to go along with steel tubing, steel bar and numerous other steel products and services. In today’s blog, we’ll dig a bit further into steel and other metal piping formats, giving you some detail on your options if you decide to go this route for your next project.

Galvanized Vs. Black Steel Pipe

If you do choose to go with steel pipes, two of your primary options are galvanized steel and black steel pipe. Here are some basics on each:

  • Galvanized steel: This pipe format includes a zinc coating that protects the steel from corrosion and any mineral deposit buildups. This protection makes these materials extremely durable, even in marine environments. Galvanized steel pipe is most commonly found in plumbing and other water-supply areas, with a lower cost than other steel types and a 30-plus-year lifespan.
  • Black steel: This pipe material has an iron-oxide coating on its entire surface – this is not the same as zinc, and black steel is generally used for areas that don’t require galvanization. It’s used to transport water and gas in many areas, plus for delivering high-pressure air and steam in certain applications. Due to its high heat resistance, it’s also often used in fire sprinkler systems. Finally, it can also often be found in various water transfer applications, including water wells that require potable water from their source.

304 Stainless Steel

If your project requires the transportation of liquids, another common material is called 304 stainless steel. This product has great corrosion resistance and durability, plus a high strength-to-weight ratio. It’s also resistant to both thermal and electrical conductivity, plus is easy to fabricate and clean. Finally, it’s non-magnetic and can be hardened using the right processes.

Brass Options

One non-steel option that’s still used in certain applications today is brass, which is sometimes found in water supply, drain lines or gas lines. Brass is made from copper and zinc, meaning it resists corrosion and is generally safe for drinking water. Brass tube or pipe can also be installed with a tight seal due to its softness, which makes it an attractive material for areas where leaks need to be prevented.
