Galvanized steel is a type of steel pipe

Galvanized steel is a type of steel pipe or fitting that has been coated, or galvanized, with a layer of zinc. For the avid DIYer living in an older home, a working knowledge of galvanized steel is important in order to properly repair or replace pipes and fittings. If your home is more than 30 years old, it’s likely your water pipes are made from galvanized steel. c section beam

Minerals in water can also build up inside galvanized plumbing pipe and cause damage through corrosion. Water pipes are galvanized to prevent rusting. Nor should the presence of galvanized steel pipes deter you from buying that dream house you’ve set your heart on. Just be aware that the limited lifespan of galvanized steel plumbing means you may encounter leaks that need fixing and, at some point in the not-so-distant future, you may need to replace the pipes. Galvanized steel pipes can be identified as grey in colour with threaded fittings. At CuraFlo, we know how to clean galvanized steel and iron pipes in the most effective and efficient way.

There’s no reason to panic if you discover your home has galvanized steel pipes in the plumbing system. Corroded galvanized pipes can result in lead being released into the tap water. Pipes made from galvanized steel are significantly heavier than modern plastic material, which makes it difficult to work with. A dielectric union separates the copper from the galvanized steel pipe; this is typically done by inserting a rubber washer between the two metals. Copper combined with galvanized steel can very quickly lead to corrosion. In newer plumbing systems, galvanized pipe is most commonly used for drains and vent pipes or for replacing existing pipes.

Observations of Corrosion of Electric Resistance Welded Galvanized Steel Pipe in Domestic Potable Water. The life expectancy of galvanized piping is about 70 years, citation needed but it may vary by region due to impurities in the water supply and the proximity of electrical grids for which interior piping acts as a pathway (the flow of electricity can accelerate chemical corrosion). Galvanized steel can last for many decades if other supplementary measures are maintained, such as paint coatings and additional sacrificial anodes The rate of corrosion in non-salty environments is caused mainly by levels of sulfur dioxide in the air.

Thermal diffusion galvanizing, or Sherardizing , provides a zinc diffusion coating on iron- or copper-based materials. Black steel pipe, on the other hand, corrodes more easily than galvanized pipe and allows minerals from water to build up inside it. The black steel pipe is also used for fire sprinkler systems because it is more fire-resistant than galvanized pipe.

As the epoxy moves through your plumbing pipes, it rolls over itself, ensuring a thorough and even coating Then, the coating is left to cure for a certain amount of time, usually 24-hours. The process of lining your plumbing pipes starts with a thorough cleaning that removes all of the corrosion and scale from inside the plumbing pipe down to the pipe walls.
