What Are Paddle Spacers & Paddle Blanks?
Paddle spacer (also known as a paddle spacer blind) and paddle blank (also called paddle blind) are essential pipeline isolation components used during maintenance or testing operations. The paddle spacer allows the pipeline to remain open for flow, while the paddle blank fully seals the line. Both are designed as per ASME B16.48 standard for line blinds.
