Also referred to as a paddle flange, paddle blank, line blank, isolation or test blind, flange skillet, and more.

A paddle blind is generally used as a temporary blocking device to stop flow in a process piping system that does not require constant maintenance.

With our in-house engineering team, we manufacture our paddle blinds on-site using precision CNC plasma and waterjet machines. With speed and precision to manufacture new and custom paddle blinds, as well as a huge inventory of rental paddle blinds in-stock and ready to ship 24/7-365 days of the year, we can have them where you need them, when you need them!

Frequently found in refineries, petrochemical and cement plants, bulk loading and storage terminals, liquid petrochemical gas and natural gas gathering systems, marine facilities, steel mills, and food processing facilities, paddle blinds are used during line repairs, maintenance and turnarounds.

Our Pledge to You

Whether you rent or purchase, every blind we ship to you will be ground to a smooth edge finish, stamped, painted and color coded for easy identification. Likewise, our industrial blinds are available with raised face dimensions (per ASME specifications), mill or serrated finish (125 / 250 RMS typical), as well as ring type joint (RTJ), oval or octagonal, and male or female configurations. Moreover, our inventory consists of 516 - Gr70 Spec Carbon Steel material made to ASME B16.47 & B16.48/ANSI B16.5 & B16.2 standards.
