Steel pipe flanges are designed to connect pipes, valves, and other equipment in a piping system. They create a secure and leak-proof joint by bolting together two flanges with a gasket in between. Stainless steel flanges are highly desired because of their excellent strength and resistance to corrosion.
Steel pipe flanges are known for their exceptional strength and durability. They can withstand high-pressure environments, heavy loads, and mechanical stresses without compromising structural integrity. This makes them suitable for demanding oil and gas, petrochemical, and power generation applications.
Stainless steel flanges, in particular, exhibit excellent corrosion resistance. They are resistant to rust, oxidation, and chemical reactions, making them ideal for applications involving water, chemicals, or corrosive substances. Their ability to resist corrosion ensures the longevity and reliability of the piping system, reducing the risk of leaks and ensuring safe operations.
The steel pipe flanges are highly versatile and can be utilized in various applications. They can be used with different piping materials like steel, stainless steel, and plastic. Moreover, they come in multiple sizes, pressure ratings, and configurations, making them customizable to meet specific project needs.
Steel pipe flanges are designed for easy installation and maintenance. They provide a secure connection between pipes, allowing for quick assembly and disassembly when necessary. This facilitates maintenance tasks such as inspection, repair, or replacement of components within the piping system, reducing downtime and improving overall efficiency.
The primary function of steel pipe flanges is to create a leak-proof joint between pipes. They form a tight seal that prevents fluid leakage by bolting two flanges with a gasket in between. This is essential in applications where leakage can result in safety hazards, environmental contamination, or financial losses.
Steel pipe flanges work with pipe flange gaskets to enhance the sealing performance. Gaskets of rubber, neoprene, or PTFE are placed between the flanges to provide a reliable and flexible seal. The choice of gasket material depends on temperature, pressure, and chemical compatibility.
Different types of steel pipe flanges are available for specific uses, allowing engineers and designers to choose the best style for their system requirements and ensure optimal performance and safety.
To ensure a leak-proof connection, pipe flange gaskets are used with steel pipe flanges. These gaskets are placed between the flange faces, creating a seal that prevents fluid or gas leakage. Common gasket materials include rubber, neoprene, and graphite, each offering different temperature, pressure, and chemical exposure resistance levels. The choice of gasket material depends on the specific requirements of the application.
To summarize, flanges are crucial in many industries to guarantee reliable connections, effective flow management, and system stability in piping systems. Flanges are vital in promoting safety, dependability, and efficiency in various fields ranging from oil and gas, chemical processing, and water treatment to power generation.

There are several benefits to using a pipe flange including: it provides a secure connection between pipes, valves & other equipment; it allows for quick disassembly by providing installation or modification access points; and it increases the strength at the joint.
The application and type of flange determine the way in which the connection is made. Always consider the fluid being conveyed through a pipeline, the operating temperature, flange type, size, pressure class/rating and other specifications prior to installation. This ensures safety during installation and operation of the piping system.
ACCESS OUR SIZE & BOLT CHART
A pipe flange has several components: a unique bolt pattern, connection type (e.g. socket weld, threaded, slip on, etc.) and face. They have varying bolt patterns that are based on the type of flange and its diameter.It is important to note that flanges do require a gasket to make the seal except for ring-type joint faces.
Pipe flanges can be manufactured from a casting (cast from a mold) or forging (using energy to change the shape of billet/ingot). They also come in various pressure ratings: 150, 300, 600, 900, and pounds. While they are available in several diameters, the larger flanges are available in the higher pressure class/rating.

Flanges also have several types of facing which include: flat face, ring-type joint, lap joint, tongue & groove and raised face. The facing is the area that is used to seal the flange.
Industry Flat-Full Face Raised Face Ring-Type Joint Face Cast-Iron Equipment X High Pressure/High Temperature (up to °F/750°C) X Low-Pressure Water Pipe Systems X Process Plants (Chemical, etc.) X Oil & Gas X X Valves XThe face itself can be serrated or smooth. There are several industries that traditionally require a specific type of facing.
There are several types of pipe flanges in a piping system; but there are 6 main types – blind, lap joint, slip on, socket weld, threaded and weld neck. Each of them has properties that determine their use in commercial, industriall and institutional applications. Always consult your project manager prior to installing any pipe flange into any application.
Raised Face or Flat Faced?
There are other types of flanges including: orifice, reducing, ductile iron backup, copper solder joint and many more.
Flanges are available in several alloys including: copper, brass, stainless steel, carbon steel, titanium, aluminum, superalloys, tool steel and alloy steel. Each alloy carries specific attributes:
Alloy Attributes Alloy SteelCan a stainless steel flange be put with carbon steel pipe?
Absolutely not, it would cause galvanic corrosion. Always consult your project team to ensure a proper, safe installation. Does Merit's offering of pipe flanges come with flange protectors? Yes. Do ANSI Flanges come in raised face (RF) and flat-faced (FF)? Yes, Merit's ANSI Flanges are raised face. The raised face can be machined off to make it the flat-faced style. Can a flange be identified without stampings on the sides? Yes, traditionally, the bolt dimensions, OD and thickness can identify which class the flange is.
