Stainless Steel Flanges: Their Types and Applications
Stainless Steel 310 Flanges
ASTM A182 SS 310 Flanges is sulfidation resistant and can be used in moderately carburizing environments due to its high chromium and mild nickel concentration. Because of their high toughness to -450 degrees F and low magnetic permeability, 310 SS Flanges are used at extremely low temperatures. Stainless steel 310 Flanges are commonly used in mildly carburizing environments, such as petrochemical applications. In irregular use, SS 310 Flanges have a high oxidation tolerance of up to 1035 degrees C and 1050 degrees C in continuous operation. Stainless Steel 310 Flanges are oxidation, sulfidation, and carburization resistant.
The following are the top 8 Stainless Steel Flanges Used in Stainless Steel Pipes:
Welded Neck Flanges
The protruding necks of these flanges make them easy to identify. Weld neck flanges are designed to withstand high pressures and temperatures and will match the pipe’s diameter and bevel.
Flanges with no visibility
These flanges are ideal for sealing vessel openings or pipe systems without a bore in piping systems or vessels that require periodic inspection. Blind flanges with or without hubs can be used. The flange can easily withstand significant tension due to internal pressure.
Flanges for Slip-On
Because they are larger in diameter than the pipe, these Stainless Steel 310 Flanges are welded to a location and are ideal for low-pressure applications. They are slidable.
Socket Weld Flanges
These flanges are used in the chemical processing industry because they are designed for high-pressure pipes with small diameters. Internally welded socket weld flanges contribute to the fatigue resistance of the product.
Flanges with Threads
These flanges can be used for a variety of applications and can be assembled without the use of welding. Externally threaded pipes are suitable for stainless steel threaded flanges, which should not be used at high pressures or temperatures.
Flanges for Lap Joints
Flanges made of low alloy steel or carbon steel are slip-on flanges that can be used with stub end fittings. They are ideal for use on piping systems that require regular inspection and maintenance, such as low alloy steel or carbon steel pipes.
Flanges for Orifices
Steel flanges are used to gain access to a line in order to metre liquids or gases. In the orifice flanges, orifice plates or flow nozzles are inserted.
Joint Flanges of the Ring Type
In high-pressure and high-temperature applications, flanges with a ring-type joint are used. The ring-type joint flanges on blind, slip-on, or weld neck flanges have a squeezable groove. Flanges help to prevent leaks in pipelines that transport media under high pressures and temperatures.
