What are Flanges?
A flange is a connection between two pieces of metal that allows the two pieces to be attached. To make a pipework system, flanges are used in various applications, such as connecting valves, pipes, pumps, and other equipment. Flanges come in different types, depending on their size and other factors. Here’s a look at some of the most common types:
Weld Neck Flanges
Weld neck flanges are also popular for their ability to create smooth transitions between pipe sections. This makes them a popular choice for applications that require a high level of flexibility, such as water and gas distribution. Designed to withstand harsh conditions, these flanges are made of heavy-gauge steel. They can also be constructed from water and gas pipelines because they are corrosion-resistant. As a result, Weld Neck Flanges are an excellent choice for locations that require high levels of durability and performance.
Slip-on Flanges
Slip-on flanges are perfect for low-pressure, low-temperature applications. They’re easy to use, cheap, and popular among the industrial community. To use a slip-on flange, you first need to slip it onto the pipe. The flange has a series of slots that fit snugly onto the pipe, and then the flange is welded onto the pipe on both the inside and outside. The result is a very durable, wear-resistant product.
They’re easy to use, and because they don’t require any pressure or temperature to function, they’re a great choice for applications that need to be kept low-cost and easy to use.
Threaded Flanges
Threaded pipe flanges are becoming increasingly popular in the manufacturing industry because of their simplicity and versatility. They are similar in design to slip-on flanges but have a tapered thread, meaning they can be attached to pipes without welding. This makes threaded pipe flanges great for use in low-pressure, low-temperature environments. Pipelines requiring tight seals, such as oil and gas, are also a good use for these seals.
Blind Flanges
Blind flanges are made of metal but don’t have a bore. This means they don’t have any openings that allow gas or liquid to flow through them. Instead, the blind flanges are fitted with seals that close off the sections of pipe they’re attached to. This type of seal is particularly important in high-pressure applications. For example, if there’s a leak in a section of pipe, the pressure inside the pipe will be too strong for the seal to hold. This could lead to a catastrophic explosion.
Blind flanges are also used to test gas or liquid flow through a pipe. By fitting them to pipe sections known to be leak-free, you can ensure that the flow of gas or liquid through the pipe is uninterrupted. This is particularly important when testing new pipelines or retrofitting old pipelines.
Socket Weld Flanges
Socket weld flanges are a great way to create a fitting for a small, high-pressure pipe like a hydraulic pipe. They can accept the pipe into the socket, creating the perfect fit.
