Threaded Flange

ASME B16.5 Stainless Steel Screwed Flanges manufacturer in India

Flanges are devices, which help connect different systems in the piping industry. A Threaded Flange can be attached without the requirements of welds. These flanges have a thread, which matches with that of the pipe. The process to join these flanges together is very easy. These flanges are also known as a Screwed Flange. This flange can easily provide access to cleaning and inspection within the systems. They are available in nominal sizes between 15NB to 1200NB. The Stainless Steel Threaded Flange is highly resistant against all forms of corrosion and oxidation in various mediums. These flanges are used in high-pressure applications above atmospheric pressure where welding is impossible. Threaded Pipe Flange is nearly similar to a slip-on flange except for the fact that they are made with tapered threads. These flanges are a preferred choice in small diameter pipes, which have high-pressure requirements.  Stainless Steel Threaded Pipe Flange possesses superior strength and excellent tensile and yield strength and can be machined easily. These flanges can be used in explosive areas. For joining pipes of different sizes the Threaded Reducing Flange is used in many applications. These flanges are also used in cases where the pressure is increased or decreased.

Reducing Threaded Flange

Threaded Blind Flange doesn’t possess a hub or a boring center. These flanges are used to seal the ends of hydraulic and piping systems. They are bolted which, makes them easy to be cleaned and maintained. The Threaded Companion Flange is available in pressure classes of 150, 300, 600, 900, 1500, and 2500. These flanges are cost-effective but are highly reliable and efficient for long periods. In the Gi Threaded Flange, the coating of zinc gives them enhanced protection in different stress-induced environments. They are produced following all international and national standards. For the Carbon Steel Threaded Flange, the concentration of carbon is higher. This enables these flanges to exhibit superior strength and toughness. Our renowned workers make use of the latest technology and the best raw materials to produce the Flange Threaded Type along with all our other products.

Bsp Flange can be produced using either tapered or parallel threads. Both the threads possess the same sizes and have an angle of 55 degrees. These flanges are produced following the British standard pipe. The Npt Threaded Flange has tapered threads, which are at an angle of 60 degrees. These flanges can be used without any sealant due to the taper. The threads can be difficult to separate if they are wound tightly. If you have any questions or want to customize any of our products, contact us for more information.
