Ring type joint and raised face flanges are two of the most popular options in the industry today. When we talk about these types of flanges and their differences, we are referring to choosing the best type of flange to create an effective seal. Today we’re going to take a look at the difference between RF flanges and RTJ flanges to help you decide which would be the best option for your business applications. Take a look through our full range of products and ring type joints or get in touch with our team if you need any help selecting flanges for your company.
What is a Ring Type Joint Flange?
To start off our discovery of the difference of RTJ and RF Flanges, let’s discover what a ring type joint flange does. Ring type joints are best used when you are working at a high pressure or high temperature. They are suitable for use at temperatures in excess of 427°C. The way in which you can identify this type of flange is that they will have a groove cut into them where the metallic gasket will fit to create a solid seal when put under compression. It fits into the space properly and ensures an effective seal is created to avoid leaks.
The Advantages of RTJs
A ring type joint gasket has many advantages over other types of gasket. It is consistently one of the best-selling types of gasket as it can create a metal to metal seal. This seal is able to withstand high pressure, heat and corrosion caused by the chemicals used in various applications. The grooves in the design create a tighter fit which is ideal for an application where space is limited. Once the gasket is tightened, it will be very resistant to vibration and movement. You’ll find that this type of gasket is readily available and easy to use, creating a very strong and reliable seal.
What is a Raised Face Flange?
To continue our explanation of the differences between an RTJ flange vs RF flange, let’s learn what a raise face flange is. You’ll find this type of flange is very commonly used within processing plants. It’s easy to recognise as the bolting circle sits lower than the gasket surfaces and the surfaces that the gasket will be attached to are raised.
The Advantages of RF Flanges
RF Flanges allow you to use a wide range of gaskets, including popular options such as spiral wound gaskets and flat ring sheet gaskets. The surface is raised and is easy to access. When it comes to replacing a worn out gasket, this process will be quicker and easier than with other gasket types you may consider. The design of RF flanges allows more pressure in a concentrated area and this type of flange is known for handling pressure well. It’s also a good option if you need improved separation between two flanges you are joining together,
How to Choose the Best Flanges for Your Business
There are a few steps that you’ll want to take in order to decide which would be the best flange option for your business needs. Don’t just think that you can choose a basic flat face or raised face flange, as often your applications may need something more complex. Review the connections and flange options to decide the best material and shape for your flange. The pressure, chemicals and temperature you will be using will help to dictate the material that your flange should be made from. You’ll find a range of metallic, non-metallic, elastomeric and fibrous options on the market today, all of which have their own set of pros and cons to consider.
The chemical resistance and corrosion concerns you have will impact the type of flange you require also. Different materials have various levels of chemical resistance and are suitable for project demands in different industries. Once you choose the right type of flanges, you may want to consider working with a professional to install them. You don’t want to go to the effort of purchasing flanges only for them not to work as you desire once they are installed. The quality of the product and the installation will ensure that you avoid leaks and issues with your processes and don’t cause any damage to your other components.
