Flanges made of stainless steel are characterized by a particularly flat shape and many holes that are located over the entire surface of the product. It is in them that the studs and bolts are placed. This type of fastening is usually used in cases where the most stable and, at the same time, strong connection between pipes is required. Connections are also used in the installation of various structures, rotating elements, and elements of pipelines.

Also, super duplex flanges made of stainless steel can be used to connect individual fittings for fastening in different pipeline sections. Collar flanges made of stainless steel should be considered separately. They have a wide distribution; therefore, they are used in many modern industries. In this way, the equipment is often connected to the main, to which, over time, it will be possible to connect a pipeline or other containers. By choosing the right stainless steel Flanges Manufacturers in India, industries can ensure the reliability and durability of their equipment and systems, ultimately leading to increased efficiency and productivity.

Peculiarities of Stainless Steel Flanges

Characteristic features of copper nickel flanges:

various modifications of seals;mounting variations;Type of connection used (threaded, blind, welded, collar, flat).

Blind-type flanges belong to a separate category of flange connections. Unlike other types of connections, they are not used to connect individual elements of the pipeline but are only responsible for the tightness index of the used bends. Thus, they replace the more familiar plugs. In the manufacturing process, it is customary to use a flange connection method:

Casting- In this case, further machining is possible as one of the budget options. It differs from grinding by the method of influencing the work surface by removing various defects.Press-forging- In this case, the method of additional processing of the working surface of the product using a lathe will be applied.

A certain amount of AISI-304, 321, and 316 steel will be required to manufacture the product. However, other steel grades can be used as the main raw material if there is a tangible benefit or a need for such manipulations. Elements are distributed based on the available design features:

when placing an element on a welded ring, GOST 12-822-80 is applied;flat flanges GOST 12-820-80;Butt-welded collar products GOST 12-821-80.

Positive Qualities of Stainless Steel Flanges

Stainless flat units have a number of such positive qualities:

High indicator of reliability and durability, thanks to many technological characteristics.With the help of a flange, it is possible to ensure the proper level of sealing at any junction of the units, with the possibility of subsequent tightening.With it, you can carry out installation and dismantling work at a regular frequency. In this case, special damage and consequences will not follow.


Based on the advantages discussed, it is clear that stainless steel flanges are a valuable component in various industrial applications. However, it is important to note that the quality of the product is crucial in ensuring its effectiveness and longevity. As such, it is highly recommended to rely on professional suppliers for duplex pipe fittings. With their expertise and experience, they can provide high-quality products that meet industry standards and regulations.
