Nextgen Steel & Alloys is engaged in producing and exporting SS Spectacle Blind Flanges. We procure stainless steel alloy to produce these flanges from approved mills. Customers can get the fastest delivery of these flanges even at a low cost. We provide these flanges in different sizes. These flanges contain a shape that is similar to spectacles. SS Spectacle Blind Flanges allow for flowing in the pipe system. If these flanges are used, then the possibility of leakage is zero. One end of these flanges is blocked, and the other end is open for flow. The SS Spectacle Blind Flange looks like a pair of glasses; Two metal discs are connected by a metal part and form a flange. These SS spectacle Blind flanges are also known as 8 shaped flanges.
Our flanges are used where the flow of fluid is done without disturbance. These flanges work well at sub zero temperatures. Our flanges are popular due to their unique properties, such as durability, strong structure, and flexibility. These flanges are safe to install and have a long service life. Our company offers SS Spectacle blind flanges that rotate easily to close and open flow in a piping system. These spectacle Blinds consist of two discs connected by a steel plate and forming a flange that separates the piping systems. During maintenance, this flange seals the equipment to prevent leaks.
Our company supplies these flanges, which fulfill the requirements of many industries like the automobile industry, railways, pipeline, and heavy engineering. These flanges are also used in fossil fuel power plants and industrial boilers. Nextgen Steel & Alloys give the training to prepare SS spectacle blind flanges for critical applications. Our company can produce SS Spectacle Blind Flanges even in odd sizes, which is hard to find in stainless steel.
