If you've got customers asking you why you need a pipe flange in a particular location, you might be wondering what the right answers are to their questions.  Fortunately, we've collected the details so that you don't need to - you can just point them to this post.  In this post, we'll talk about what a pipe flange is, the different types, where they tend to be located, whether they're considered fittings, and how to select the right pipe flange for your application.

What is a Pipe Flange?

Used to connect pipe sections, flange faces bolt together to create a strong, watertight connection that will hold up well under high temperature or high pressure applications. It creates a much stronger joint than simply using a coupler or other pipe fittings to connect two pieces of threaded pipe, such as fitted iron pipe systems.

However, there is a wide range of different flange types, designed to meet a range of disparate plumbing standard sections, such as ASME B16.47 or ASME B16.5. One common feature is bolt holes in the flange facing, which allow the flange to be securely fastened to the surrounding material. In the next section, we'll discuss different types of pipe flanges that you may encounter.  Pipe flanges also come in several alloys some of which include:  stainless steel, brass, chrome-plated brass, copper & carbon.

Where are Pipe Flanges Located?

Generally speaking, a pipe flange is located at points where regular disassembly, maintenance, or cleaning will be taking place. This can include making it possible to bolt pipe systems directly to equipment, fittings, or other features quickly, easily, and securely.

Are Pipe Flanges Considered Fittings?

Pipe flanges are considered a very popular type of fitting in plumbing systems, and are often used when pipes are used for non-plumbing systems as well, such as railings, racks, and similar applications. However, they often provide an additional level of security to the fitting, because the bolt holes allow the fitting to be secured to the surrounding structure.

How Do I Choose the Right Pipe Flange?

Pipe fittings will vary based on your application. However, by having a better grasp of how pipe flanges work, you'll be able to answer your customers' questions much more easily, improving their confidence in your ability to do the job they've hired you for.
