SPECTACLE BLIND FLANGES / FIGURE 8 BLANK
When it comes to industrial piping systems, the importance of flanges cannot be overstated. They are essential components that connect various pipes, valves, and equipment, ensuring the safe and efficient operation of the system. Among the many types of flanges available, one that stands out for its versatility and benefits is the spectacle blind flange. This unique flange is designed to provide a temporary or permanent closure of a pipeline, allowing for maintenance, repairs, or modifications without interrupting the flow of fluids or gases. But that's not all - spectacle blind flanges offer many other advantages, such as cost-effectiveness, flexibility, and improved safety. We'll take a deep dive into the world of figure 8 blank flanges, exploring their construction, uses, benefits, and more, to help industries make informed decisions when choosing flanges for their piping systems. So, buckle up and get ready to discover the wonders of spectacle blind flanges!
​
Spectacle Blind Flanges are safety devices used to isolate a piece of equipment or a section of line when the equipment or line needs to be inspected or removed from service. The flange is formed by joining together two metal discs with a section of metal. Spectacle blinds are also known as figure 8 flanges. The thickness of the spectacle blind is specified based on the line pressure and pipe size. Tesco Steel & Engineering manufacture a wide range of high quality Spectacle Blind Flanges in India. We offer these flanges in ASME/ANSI/DIN standards.
