Harsh Flanges, based in Mumbai, India, stands out as a top manufacturer and supplier of high-quality Spacer Blinds Flanges, which are essential for effective flow control in piping systems. Often referred to as paddle spacers or spectacle blinds when used with blind flanges, these components play a crucial role in either blocking or allowing flow in pipelines, providing a safe and efficient way to isolate sections during maintenance or inspections. Crafted from premium-grade carbon steel, stainless steel, or alloy steel, our spacer blinds meet ASME, ANSI, and other international standards. Harsh Flanges is recognized for its precise fabrication, prompt delivery, and outstanding service in industrial pipeline solutions.
Spacer Blinds Flanges are generally constructed from materials like stainless steel (SS 304, 316), carbon steel (A105), or alloy steels, depending on the specific operating conditions. The stainless steel options offer excellent corrosion resistance, featuring 18–20% Chromium and 8–12% Nickel, while carbon steel delivers robust mechanical properties at a more affordable price. These flanges typically showcase tensile strength ranging from 485–620 MPa and yield strength between 250–310 MPa. They are engineered to uphold structural integrity under varying pressures and temperatures, ensuring dependable performance in systems that require periodic flow isolation or operational switching.
