A flange casting is typically a cast ring designed to connect the sections of a pipe or other machinery which requires a connecting joint.
Most cast options are outdated and flanges provided to modern specifications are made from plate or forged carbon steel or stainless steel. Before you buy flanges, it is crucial to note that these flanges come in different measurements, diameters, sizes, types/forms, and materials.
Several types of flanges are available for different types of applications. Therefore, all you have to do is choose your product on a per-project basis. When we talk about the materials to use in your applications, a variety of factors come into play. Therefore, some crucial aspects that are required to be considered while buying stainless steel flanges are discussed in this blog:
Choose the right stainless steel flange
It is crucial to note the diameter of the pipes to which the flange needs to be connected. Also, you must understand that these pipe connections could be ERW, welded, seamless, etc., and would help you choose the required flanges.
Stainless steel pipe flanges, rings, and discs attach to the pipe to increase the strength or support based on the existing connection type from the pipe, which are usually welded or screwed to the pipe end. These pipe flanges are designed per the specifications and are easy to customize by established manufacturers.
Choose the flanges based on the project design
SS Flanges are accessible in numerous grades. The client’s selection of products needs to rely on the budget and project you need. However, top-quality products need to be costly and need to be sturdy.
Both SS 316L Flanges and SS 304L Flanges are corrosion resistant alloys with a high, 95% alloy composition. SS 316 and SS 304 belong to the chromium-nickel category and are grades that withstand standard corrosion. It needs to be durable, resists most basic chemicals, and hold more excellent resistance to numerous types of deterioration.
Selecting SS Flange types available in market
Here’s how you can select the SS flange types available around the market:
SS Slip-on flanges
The bore size of the slip-on flange as a standard is slightly larger compared to the outside diameter of the connecting pipe, as the pipe has to slide inside the flange then needs to be connected by the execution of the fillet weld around the perimeter.
SS Weld neck flanges
SS Weld neck flanges are helpful in high/low-temperature applications and high-pressures that require an unrestricted fluid flow conveyed by the piping system. These butt-weld end connection flanges are most common in industrial applications to ensure a high strength connection between assemblies.
SS Blind Flanges
Most piping systems require regular inspection and blind/blank flanges are common inspection point. This type of flange, when selected according to the proper pressure class, can easily handle the stress caused by the liquid’s operating pressure and pressure flowing through the pipe. They are helpful to ‘blank off’ valves, pipelines, etc… in almost all applications.
SS Threaded Flanges
You can assemble the flange without welding, and hence it is easy to remove. You do not have to use it for applications where bending stresses involve high pressure or temperatures. A seal weld is useful in conjunctions with times.
SS Lap joint flanges
It is a type of slip-on flange but made for connecting to a stub end for rotation. Lap joints are helpful to maintain carbon/low alloy steel pipes with additional mechanical properties. These flanges are similar to slip-on flanges but are characterized by the radius-rounded interior edge of the flange face and generally come with a taller hub.
SS Socket-weld flanges
Smaller diameter socket weld and counter bore flanges handle the applications with high pressures like steam lines but with limited spacing. You must ensure durability possess internal welds—the bore of the pipe and flange match provides a good flow connection.
SS Orifice flanges
If you want to combine two pipeline components in assemblies for which you need easy access to modify, inspect, and clean, orifice sets are commonly recommended. Types need to vary as per the use and maintain high-pressure applications, and line blanks are also usually installed for maintenance or operating differentials.
Conclusion
Even if you find a range of flanges in the market, we offer you the best quality for your establishment. Nothing can beat stainless steel flanges in most lighter corrosion applications. The above blog signifies the buying guide of stainless steel flanges above; we hope you’ve now good knowledge about various steel flanges and whether they are the best option for you or not.
