Galvanized piping

At Detroit Nipple Works, we carry a variety of piping. Galvanized piping is one of our more popular selections.

What makes a pipe galvanized?

A pipe becomes galvanized when a protective zinc coating is applied to steel or iron. The galvanization process is to prevent rusting. Also, this process makes galvanized pipes ideal for plumbing and other areas where water is used. 

The galvanizing process protects in two ways:

The exposed steel is protected by the zinc coating because even if the coating is scratched the remaining zinc still protects it. The second way that it protects is that the corrosion-resistant zinc coat protects against corrosive substances reaching the more delicate metal.

What is the history of galvanized piping?

Galvanization has been associated with zinc coatings to the exclusion of other metals for a long time. Galvanic paint is was patented by Stanislas Sorel in Paris, France in 1837.  The earliest known example of galvanizing iron is found in 17th century India armor. Galvanized piping replaced cast iron and lead in cold-water plumbing in the early 20th century.

Galvanized piping can last up to 70 years depending on the thickness of zinc in the original galvanization and whether or not the galvanization was on the inside and outside. Also, copper and plastic piping have replaced galvanized piping for interior drinking water since World War II. Galvanized pipes are still used in outdoor applications. They are best for larger construction projects. Today, galvanized pipes can be found in sewage plumbing and farm irrigation.
