Spades & Ring Spacer Flanges
Reliable Pipeline Isolation Solutions for Safe Industrial Operations
Spades & Ring Spacer Flanges are essential pipeline isolation components used in industrial piping systems to safely control the flow of liquids, gases, and steam during maintenance, inspection, or plant shutdowns. A Spade (Paddle Blind) completely blocks the flow, while a Ring Spacer (Spacer Ring) allows unrestricted flow through the pipeline. Together, they provide a safe, efficient, and visible method of isolating process lines.
These isolation devices are commonly installed between two standard flanges and are widely used in industries where operational safety, maintenance efficiency, and regulatory compliance are critical.
Royal Steel India manufactures and supplies premium-quality Spades & Ring Spacer Flanges in various sizes, pressure classes, and material grades, ensuring reliable performance and compliance with international standards.
