How Are Galvanized Pipe Fittings Made?

Galvanized pipe fittings are made from steel or iron that has gone through a galvanizing process and then annealed to create malleable cast iron fittings. The galvanizing process is where a protective layer of zinc is applied to the metal. This layer of zinc acts as a barrier, protecting the base metal from moisture and other environmental factors; reducing the likelihood of rusting and extending the life of the product.

The thread standards of the galvanized pipe fittings we provide include NPT, BSPT, etc.

Methods of Galvanizing Pipes We Use

There are two main methods of GI fittings:

  1. Hot-dip galvanizing (HDG): This method involves dipping the pipe into molten zinc at a temperature of approximately 450°C (842°F). The result is a thick, durable zinc coating that provides excellent protection against corrosion. Hot-dip galvanized pipes are often used in outdoor applications and industrial settings.
  2. Electrogalvanizing: In this process, zinc is applied to the metal surface through an electroplating process. While the zinc layer is thinner than that produced by hot-dip galvanizing, it still offers strong corrosion resistance, making it ideal for indoor applications.

Types of Galvanized Pipe Fittings

Galvanized pipe fittings, also known as GI pipe fittings, come in a variety of shapes and sizes to meet the needs of different piping systems. Common types include:

  1. Elbows: used to change the direction of a pipe. We offer common 45° and 90° elbows.
  2. Tee: allows branch lines to be connected to the main pipe. We also have reducing tees.
  3. Couplings: connect two sections of pipe together.
  4. Unions: provide a removable connection between two pipes.
  5. Caps and plugs: used to close the ends of pipes.
  6. Reducers: connect pipes of different diameters.

What Should You Consider When Choosing Galvanized Pipe Fittings?

  • Size: The size of the fitting should match the size of the pipe.
  • Material: The material of the fitting should be suitable for the application environment.
  • Pressure rating: The pressure rating of the fitting should meet the pressure requirements of the application environment.
