IBR Approved Flanges

Flanges are used to connect pipes and valves in different piping systems. The IBR Approved Flanges are manufactured following material grades, dimensions, and pressure classes set by the Indian Boiler Regulation. These flanges offer a continuous flow of material without any obstruction and leakages. They are designed to resist all forms of corrosion and extreme temperatures. Apart from this, they have good tensile and yield strength. These flanges are widely used in industrial systems, the automobile industry, sewage systems, food processing, plumbing, etc. We are the leading manufacturer and supplier of IBR Approved Flanges. We aim to produce top-quality products, which are available to all at reasonable rates.

We are manufacturer of IBR Approved Slip on/ Blind Flanges

The IBR Blind Flange is made without a bore or hub. These flanges are used to close ends of high-pressure pipes or valves. These flanges can be fixed permanently or bolted. The IBR Approved Slip on Flange is a cost-effective and a popular flange. These flanges can be easily slid on pipes and welded at precise locations. The IBR Approved Forged Flange is formed when thermal and mechanical energy is used to change their shape in a solid form using steel billets. Our renowned workers make use of the best raw materials and latest innovative technology while designing all our products.

To connect pipes of different sizes, the IBR Reducing Flange is used. These flanges are easy to weld on other pipes and are preferred in low-pressure applications. The IBR Approved Threaded Flange act as companion flanges. These flanges are very common while creating reducing connections. These fittings come in pressure ratings of 2000-6000. All our products can be customized according to your requirements in different shapes and sizes. If you have any questions about our flanges or other products, contact us for more information.
