In this segment, we’ll take a closer see at the key benefits of stainless steel flange and why they’re so well known.
Erosion resistance
The most unmistakable include of stainless steel flanges is that they are not simple to rust. Since it contains chromium and nickel, a defensive film will be shaped on the surface, which can piece a parcel of erosion such as corrosive, antacid, and salt. Subsequently, stainless steel flanges can too be utilized for a long time in a few chemical plants or places such as the ocean side where rust is simple to occur.
High temperature resistance
stainless steel flanges can moreover keep up a great condition at tall temperatures, particularly materials such as 304 and 316, which will not misshape or gotten to be fragile due to tall temperatures. Subsequently, it is regularly utilized in channels that require to be safe to tall temperatures, such as steam channels or kettle systems.
High strength
stainless steel flanges are exceptionally solid and are not simple to break or distort indeed beneath tall weight. This implies that it is especially reasonable for utilize in places that require to withstand tall weight, such as oil pipelines or characteristic gas pipelines.
Good fixing effect
As long as the establishment is adjust, the fixing impact between the stainless steel flanges and the pipeline is exceptionally great, which can successfully anticipate fluid or gas spillage. With the right fixing gasket, the fixing impact can be advance progressed, particularly in high-pressure or high-temperature frameworks.

Stainless steel Non-Standard Flange
Size of Stainless steel flange
Stainless steel flange: 1/4″-160″, DN8-DN4000
Stainless steel flange Pressure-Temperature Class (Service Rating)
Stainless steel flange are classified as per their pressure-temperature ratings which are designated as 150#, 300#, 400#, 600#, 900#, 1500# and 2500#. Large diameter Stainless steel flanges that is 24” to 60” are available up to 900# class. Pressure-temperature ratings are maximum allowable working gage pressures in the bar & the temperatures in degrees Celsius.
Higher the rating, heavier the Stainless steel flange and can withstand higher pressure and temperature. When the temperature goes up, the pressure goes down, and vice versa. Please note that different material has different pressure ratings.
Applications of stainless steel flanges
Oil and gas field
Stainless Steel Flanges are frequently utilized in the extraction and transportation of oil and gas since of their erosion resistance and tall weight resistance, particularly when interfacing hardware such as pipelines, valves and pumps, which can guarantee the security and solidness of the framework beneath tall weight conditions.
Chemical industry

They are ordinarily utilized to interface stainless steel pipelines to guarantee cleanliness and security amid the generation process.
Water treatment and natural assurance ventures
In natural assurance ventures such as sewage treatment and seawater desalination, the erosion resistance and solidness of Stainless Steel Flanges make it an perfect choice for interfacing pipelines and gear, which can guarantee the long-term and steady operation of these frameworks.
Apart from the type, you have to pay attention to some important characteristics when selecting the best flange for your specific applications. These include the size, the pressure class and the material. Let’s take a closer look to some of them.
Selecting the Size
To select the flange size, you need to refer to ANSI/ASME standards. These standards provide the sizing of the flange for the specific pipe diameter that will be connected to the flange. They usually include tolerances together with requirements and recommendations for flange bolting and flange gaskets.
Pressure Class
The pressure class makes reference to the pressure and temperature capacity of the flange. The term is used interchangeable with others, such as “pressure rating”, “class”, “#”, “Lb” or “Lbs”. ANSI/ASME standards are also applicable, and according to ANSI/ASME B16.5, there are seven flange pressure classes: 150, 300, 400, 600, 900, 1500, and 2500. These values are tightly related to sizing too. While two flanges may have the same bore size and the same material, having a higher class means it is bigger, heavier and more robust to withstand higher temperatures and pressures depending on the material. For example, ASME B16.34 takes care of the class for the most common flange materials which are carbon, alloy and stainless steels.
Selecting Material
The usual recommendation is to use a flange made of the same material as the pipes and fittings that will be connected to the flange or at least a compatible alloy. For example, in the case of titanium piping, the best choice would be titanium flanges or zirconium flanges. The idea is that the chemical composition of the materials does not create undesired reactions, especially when in contact with process fluids. ASTM standards apply for the specifications and requirements of the materials. ASTM standards assign a grade for easy identification of the material and describes the chemical composition in percentages. Common ASTM specifications for flanges are A105, A182 and A350. For titanium flanges, the ASTM standard gives specifications such as B363 and B381.
