Blind Flanges

Raised Face Stainless Steel Blind Flanges, Manufacturer Of ASME / ANSI B16.5 Blind Flanges Supplier in India.

A vital part of piping systems, blind flanges are mostly utilized to seal a pipe's or pipeline's end. While blind flanges are solid discs without a center hole, normal flanges are made to connect pipes. They offer piping systems a safe closure for their ends, enabling maintenance, inspection, and modification without causing systemic disruptions. When a pipeline segment needs to be temporarily closed off or when a permanent end closure is needed, blind flanges are frequently utilized. They play a crucial role in keeping debris, moisture, and other impurities out of the pipeline, which could jeopardize its integrity. Blind flanges have the dual purpose of sealing and blocking off areas of a pipeline for maintenance or repairs.
To meet the needs of diverse pipeline types and operational specifications, these flanges are available in a range of diameters, materials, and pressure ratings. Common materials are alloy metals, carbon steel, and stainless steel. These are selected depending on the corrosive nature of the fluids being conveyed, as well as variables like temperature and pressure.
