Harshita Stainless provides the best Stainless Steel Spectacle Blind Flanges in Delhi, India. These blind flanges are applied for semi-permanent pipe section isolation for maintenance or testing purposes. They are manufactured using SS 304, 316, and 904L and provide strength, corrosion resistance, and sound pressure containment. ASME B16.48 compliant, our spectacle blind flanges are extensively used in industries such as oil & gas, petrochemical, and power generation. Harshita Stainless provides accuracy machining and long-term performance, delivering these key components ready to use in high-pressure, high-temperature conditions in India.
Made of SS 304/316/904L with chromium (18–23%), nickel (8–28%), and up to 4% molybdenum, these flanges are offered with tensile strength of 485–620 MPa and yield strength of 170–250 MPa. The flanges are resistant to oxidation, thermal cycles, and corrosive media with stable mechanical behavior. The design of the flange provides strong sealing ability and structural integrity.

Stainless Steel Spectacle Blind Flanges typically do not require corrosion protection coatings due to their inherent corrosion resistance. However, in highly corrosive environments, additional coatings may be applied for enhanced protection.
These flanges find applications in chemical plants, refineries, offshore facilities, and pipelines for easy inspection and isolation. Spectacle blinds allow for safe system operation by moving between the open or closed positions without dismantling. Harshita Stainless provides them throughout Delhi and India, serving industries that require schematized maintenance and leak-tight sealing in hostile processing conditions.
