High-Quality Figure 8 Blanks / Spectacle Blinds – ISO Certified, ASME B16.48 & ANSI B16.5 Flanges, EN 1092-1 and API 590 Compliant, Class 150 to 2500 Ratings, MSS SP-44 Approved Manufacturer. Bhavani Industries is a leading manufacturer and supplier of Figure 8 Blanks, also known as Spectacle Blinds, designed for safe and reliable flow isolation in piping systems. These components consist of two metal discs—one solid (the “blank”) and one with a bore (the “spacer”)—connected by a web or tie bar, resembling the shape of the number 8. Figure 8 Blanks are primarily used during maintenance, inspection, or shutdowns, allowing for easy switching between open and closed positions to isolate specific sections of a pipeline without disassembling the system. They are widely used in critical process applications where absolute flow shutoff is required. We offer Figure 8 Blanks in sizes ranging from ½” to 36”, with thicknesses and dimensions in accordance with ASME B16.48, ANSI B16.5, and customer specifications. These components are available in a variety of pressure classes, such as Class 150, 300, 600, 900, 1500, and 2500, and are manufactured using high-grade materials including Stainless Steel (304, 316, 321, 347, 904L), Carbon Steel (A105, A516 Gr.70), Alloy Steel (F11, F22, F91), and Nickel Alloys (Inconel, Hastelloy, Monel). Each product is machined with precision, ensuring proper fit and sealing in high-pressure and high-temperature applications. Figure 8 Blanks offer several advantages, including ease of installation, enhanced safety during equipment servicing, and clear visual confirmation of open or closed status. They are extensively used in industries such as oil & gas, petrochemical, chemical processing, power generation, refineries, and offshore facilities. At Bhavani Industries, all Figure 8 Blanks undergo stringent quality testing, including dimensional inspection, PMI, hydro testing, and third-party inspection, to ensure long-term performance and full compliance with international standards.
