The Different Types of Pipe Flanges in San Jose, CA

Any plumber or welder is going to be highly familiar with the flange. This is, after all, one of the most commonly used joining methods in welding, and a joining method frequently used for pipes in plumbing. A flanged joint features three distinct components: the flanges, the gaskets and the bolting, all of which are put together with a fitter.

There are a number of different types of flanges in San Jose, CA that can be used. Here are just a few examples of some of them:

• Threaded: Threaded flanges, also known as screwed flanges, feature a thread inside the flange bore, which then fits on the pipe with some matching male thread on the pipe. This makes for a quick and easy connection, but one that isn’t necessarily the best suited for high-pressure and high-temperature applications. You’ll mostly find threaded flanges used for utilities like air and water, so you can expect to see them a lot in plumbing situations.
• Socket weld flanges: Socket weld flanges feature a female socket that the pipe runs into. Fillet welding is then performed from outside the pipe. Generally, this is a kind of flange used for small bore piping, and it is only suitable in low temperatures and pressures, again making plumbing a suitable application.
• Slip-on flanges: A slip-on flange features a hole with a hole matching the outside diameter of pipe through which pipe can pass. The flange gets placed on pipe and fillet welded both from the inside and outside. You can use this kind of flange for both low-pressure, low-temperature applications, and can find it in a variety of sizes, include sizes that are large enough for big bore piping that includes storage tank nozzles. These types of flanges are also typically forged and provided with the hub, but sometimes they’re also fabricated from plates and may not come with the hub.
• Weld neck flanges: These flanges are perhaps the most widely used flange you’ll find in process piping, as it offers the highest level of joint integrity when butt welded with a pipe. These flanges are appropriate for high-pressure and high-temperature applications. They are heavy-duty, bulky and costly in some circumstances, which means they’re likely to be overkill for most home plumbing systems.
• Lap joint flanges: These flanges have two main components: a loose backing flange and a stub end. The stub end gets butt welded to the pipe, and the backing flange moves freely over the pipe. The flange can be made with a variety of materials, even ones different than the stub material. Typically, you’ll find them in carbon steel, which cuts down on costs. These flanges are most likely to be used in situations where frequent dismantling is required, or where you don’t have as much space to work with, because they’re more efficient at being put together and taken apart.
