Flanges are the second most common connecting method after welding and provide a secure way to join pipe systems with a wide variety of valves, equipment, as well as other components of nearly any processing system.
Flanges increase system maintenance adaptability by facilitating faster disassembly and better access to individual system components. There are typically three pieces involved in a flanged connection:
● Pipe Flanges
There are often designated gasket and fastening materials that are either constructed from the same or authorised materials like the components of piping that you’re trying to join. Flanges made of stainless steel are among the most popular types. However, flanges come in many different materials, so it’s important to find one that works for your application. Ablaze Lining an excellent Lined Reducing Flange manufacturer in Vadodara can fulfil all of your industrial flanges requirements.
Materials like Chrome Moly, Inconel, Monel, as well as a wide variety of others are frequently used as flanges. Your individual requirements and your system will determine which option is the best fit.
Common Types of Flanges:
However, flanges are not a “one size fits all” component. If you want your piping system to run smoothly, last a long time, and cost as little as possible, it’s not just about finding the right size of flanges; it’s also about finding the right flange design. Take a look at this overview of the most popular flange styles!
– Threaded Flanges:
This type of flange, often known as a “screwed flange,” contains an internal thread that matches with a pipe’s male thread. Threaded connections eliminate the need for welding in many applications. If you want to join two pipes together, all you have to do is match the threading.
– Socket-Weld Flanges:
Socket-weld flanges have a connection where the pipe is placed into the flange and then secured with a single multi-pass fillet weld, making them perfect for the pipes with smaller diameters in low pressure as well as low temperature settings. Due to the lack of threads at the end, this sort of welded flange is more easier to install than others.
– Slip-On Flanges:
To support systems with greater flow rates and throughput, a wide variety of slip-on flange sizes are readily accessible. Flanges are easily installed by matching the pipe’s outer diameter to the flange’s inner diameter. Attaching the flange requires a more technical method of installation, namely a fillet weld on both sides.

– Lap Joint Flanges:
Lap joint flanges are two-piece assemblies that attach a stub end to a pipe or fitting by butt welding it to a backing flange. This style’s layout is a major selling point for applications when space is at a premium, as is the case with many maintenance- and repair-oriented systems.
– Weld Neck Flanges:
Weld neck flanges are installed using butt welding, just as lap joint flanges. However, they are the preferred material for process pipes because of their durability, reliability, and resistance to failure even under extreme conditions like high pressure and high heat.
– Blind Flanges:
Blind flanges are simply boltable blank discs used to terminate or isolate pipe systems. Properly placed with the appropriate gaskets, they can form a watertight seal that can be easily broken if necessary.
– Specialty Flanges:
Common types of flanges include those described above. On the other hand, a wide variety of specialty flange types are available to accommodate a wide variety of applications and settings. Flanges with a nip, weld, expansion, aperture, long weld neck, or reduction can also be used.
When choosing the best flange for your piping system, design is only the beginning. Flange performance and durability are also affected by other characteristics, such as face type.
The seal generated by a flange and the gaskets required to install it are both affected by the facing type. Normal facial features include:
● Flat Face (FF):
Flat face flanges have a smooth, level face, and they use a gasket that makes full contact with the flange on all but a small section.
● Raised Face (RF):
These flanges have a raised ring around the bore and a gasket that fits inside the bore’s circumference.
● Ring Joint Face (RTJ):
This sort of face is typically used in high-pressure-and-temperature applications, and it has a groove that a metal gasket sits in to provide a seal.
● Tongue and Groove (T&G):
There are corresponding grooves and protrusions on each sides of these flanges. This facilitates assembly because the flanges may align themselves, and a reservoir is provided for the gasket glue.
● Male & Female (M&F):
These flanges employ a gasket retention method similar to that of groove and tongue flanges by means of a paired set of grooves and elevated parts. Gaskets can be retained on the female face, allowing for more precise positioning and a wider selection of gasket materials than with tongue and groove flanges.

When it comes to building, updating or maintaining the piping system, the flange dimensions are the next most important consideration after the flange’s functional design. However, the correct sizing of the flange relies on taking into account the gaskets and how they contact with the pipe. A few things that are usually taken into account include:
● Outside diameter:
● Bolt circle diameter:
● Pipe size:
● Nominal bore size:
