Piping Systems
Flanges play a crucial role in connecting pipes across various industries, such as oil and gas, chemical, or even water treatment.
Flange Types Basics
Flanges provide a reliable and efficient way to connect pipes and other components. Additionally, they help ensure the security of the system.
What Is A “Flange”?
Per Merriam Webster, “A rib or rim for strength, for guiding, or for attachment to another object”.
In layman’s terms, a flange is a part that allows two objects to be mated together through various processes. (Pipe to Pipe, Pipe to Tank, Pressure Vessel to……etc)
A flange serves as a protruding rim or collar employed to link two pipes or other constituent parts. Flanges are typically made of metal but can also be made of plastic or other materials.
Flanges are used in a variety of
applications, including:
Machinery
Flanges are also used to connect components in machinery, such as engines and turbines.
Structural Applications
Flanges, such as bridges and buildings, are also used in structural applications.
Flanges are typically classified by their type, size, and material. The flange type depends on the application and the type of connection required.
The size of the flange is determined by the diameter of the pipe or other component it will be connecting. The application and the environmental conditions determine the flange’s material to which it’ll be exposed.
Flanges are an important part of many engineering systems. They provide a reliable and efficient way to connect components and transfer fluids and gases.

In conclusion, selecting the right flange type is essential for ensuring safety, efficiency, and durability in any piping system. Weld neck flanges, known for their strength and reliability, are ideal for handling higher pressures due to their seamless connection via butt welds.
Other options, such as slip-on or lap joint flanges, cater to specific applications where flexibility or cost savings are priorities. Each flange type offers unique advantages depending on your system’s needs.
Most Popular Flange Styles
Weld Neck Flange
Our most frequently requested flange, the Weld Neck Flange features a neck extension and weld bevel. Provides a natural form connection ideal for larger, high-pressure applications…
Slip On Flange
A simple alternative to the Weld Neck flange, a Slip On Flange is designed to accept the pipe into the center/bore, allowing welding around the outer diameter of the pipe…
Blind Flange
Designed to cap off a line, a Blind Flange has no bore or inner diameter. They are often altered to include NPT threads or custom bore holes to function as hubless Slip On flanges…
Socket Weld / Counter Bore Flange
Socket Weld Flanges feature a recess in the bore to accept pipe insertion before a single fillet weld is applied around the outer joint. Ideal for smaller, high-pressure piping…
Threaded / Companion Flange
Threaded or Companion Flanges contain a female NPT threaded center for connection to male threaded piping. These flanges are commonly implemented in reducing connections…
Lap Joint Flange
Lap Joint Flanges are intended to saddle over a stub end fitting. They feature an extended hub and a machined radius at the base of the flat face…

Frequently Asked
Questions
The slip-on flange is one of the most commonly used flange types due to its ease of installation and cost-effectiveness. It is widely applied in low-pressure, non-critical systems where welding is required but precise alignment is not crucial.
Raised Face (RF): Features a small raised area around the bore for better gasket compression, commonly used in high-pressure applications.
Flat Face (FF): A flat surface across the flange face, suitable for low-pressure systems and softer gasket materials.
Ring Type Joint (RTJ): Features a grooved face that accommodates a metallic ring gasket, designed for high-pressure and high-temperature environments.
The weld neck flange is the strongest type of pipe flange. Its long, tapered neck provides superior stress distribution and structural integrity, making it ideal for high-pressure and high-temperature systems, as well as applications involving severe conditions like vibration or thermal expansion.
The main types of pipe flanges include weld neck flange, slip-on flange, socket weld flange, lap joint flange, threaded flange, blind flange and ring type joint (RTJ) flange.
