Katariya Steel Distributors is a supremely leading manufacturer, exporter and supplier of Blind Flanges. We manufacture our products with premium quality raw materials that are available in the market. Being one of India’s most reputable suppliers of Blind Flanges, we supply them at a competitive price range.

Blind Flanges are known to function similarly to a plug or a cap. It is used to terminate the end of a piping system. These Blind Flanges are basically a flange that does not have a hub or a boring centre. These Blind flanges have a face thickness of a flange, a matching face type and a similar bolting pattern. These Blind flanges allow easy entrance to the interior of a vessel or pipe, unlike a cap that is welded.

These Blind Flanges are quite versatile and they can also be used to seal a nozzle opening on a pressure vessel. These flanges are mostly used for testing the flow of a certain gas or liquid through a pipe or a vessel. Blind flanges are popularly used for high-pressure applications. They are made in all steel material grades like stainless steel, carbon steel and alloy steel. We make sure that all our products go through a number of tests to ensure their quality, safety and durability. We verify all our products before supplying them to our prestigious customers.

Blind flanges can handle high-pressure applications, making them useful in a wide range of industries. Pipe engineering businesses, public services, waterworks, power generating industry, shipbuilding, piping systems, pharmaceutical industry, oil refineries, petrochemical industry, and many more industries use these flanges. These blind flanges have a variety of advantages and capabilities, making them quite handy. They can work in high-pressure and high-temperature environments without breaking down. Blind flanges of the highest quality are provided to our customers.

What are the features of rf blind flange?

An rf blind flange is a specialized type of pipe flange designed for piping systems and pressure vessels. They are made up of two pieces that clamp together tightly and can be used to keep pipes, valves, and other components separated while ensuring the pressure inside the system remains intact. One distinct feature of RF blind flanges is that they do not include a bore or center hole—making them ideal for full-closure applications such as plugging off an unused port or line. Additionally, RF blind flanges typically have raised faces on both sides, which offer extra support and sealing capabilities when matched to a companion flange and gasket of similar dimensions. Finally, these flanges are incredibly reliable due to their low cost and easy installation compared to other traditional flanges.

What are the uses of alloy steel 4 inch blind flanges?

Alloy steel 4 inch blind flanges are incredibly useful in various piping systems, providing durability and stability. From plumbing applications to automotive and aerospace industries, these flanges help connect two pipes or tubes without using extra space or materials. Since they come in multiple dimensions and pressure ratings, they can be used to support light-duty tasks and more demanding applications requiring corrosion resistance and high tensile strength. With their reliable sealing abilities, relatively low cost, and easy maintenance and installation methods, alloy steel 4 inch blind flanges have become an essential component for many industries. They are sure to remain a favorite for years to come.
