PADDLE BLINDS PRODUCT DESCRIPTION
Paddle Blinds, also known as spade blinds or line blanks, play a pivotal role in ensuring safety and operational efficiency in pipeline maintenance and fluid control systems. These flat plates, inserted between flanges within piping systems, serve as temporary barriers to stop or regulate the flow of liquids or gases during inspections, repairs, or testing. Made from carbon steel, stainless steel, or other durable alloys, paddle blinds are designed to withstand high pressures and temperatures, catering to the rigorous demands of industries like oil and gas, petrochemical, and power generation. Their ease of installation and removal makes them a preferred choice for system isolation, offering a cost-effective and reliable method for ensuring workplace safety and preventing potential leaks or accidents. With various thicknesses and sizes available to match different piping specifications, paddle blinds are essential tools for maintaining uninterrupted and secure operations in complex industrial environments.
Paddle blinds find frequent use in refineries, chemical plants, petrochemical plants, cement plants, steel mills, storage terminals, and food processing facilities.
Also referred to as a paddle blank, line blank, skillet blind, blind spade, isolation or test blind and more.
We constantly innovate new piping isolation solutions and enhance our products. We have two options for blinds: the patented EZ Lock Blind Rack® and our custom industrial blind solutions. Our custom solutions include EZ Vent-Purge®, EZ Vent®, EZ Purge®, and EZ Guillotine™ blinds. These options can help you save time and money.

You will receive your paddle blinds with smooth edge finishes, stamped, painted, and color-coded for easy identification, whether you rent or buy, that adhere to ASME specifictions.
Frequently Asked Questions
We are the actual manufacturer, not just a reseller. Since 1982, each blind is crafted with perfect symmetry, clean edges, fresh paint, marked or stamped, and color-coded handles for easy flange rating identification. Moreover, unlike others who may claim this, USA Industries has the largest stock for immediate delivery and in-house production.
Most requests are for 5/16" thickness, although 1/4" or 3/8" are also very common.
T-handles, 7 handles, and Straight handle. We can also make custom handles for you.
Yes. We will customize your blind to your exact specifications.
We stock our isolation and hydrotest blinds with a mill finish and offer a 125/250 RMS serrated finish as a standard option, but we can manufacture to your exact requirements.
The term "paddle blind" is a general term that doesn't specify the thickness or purpose of the blind (whether for isolation or testing).
A "hydroblind," also known as a "hydrotest blind," is designed to withstand the maximum pressure during pipe testing according to ASME specifications.
Some companies exclusively use hydroblinds for isolation or testing, considering it a safer option. This ensures the blind can withstand latent pressure buildup in the line, unlike the 5/16" thickness isolation blind that might fail if the pressure rises significantly.
This is dependent on the flange's AMSE rating. Sizes and thickness are manufactured to the ASME 16.48, API 590, ASME 16.5 specifications and will hold the pressure that the spec calls for.
We will manufacture your paddle blind(s) in any alloy you require, so long as the material is available.
Our color-coded handles allow you to easily identify the flange rating for the blind(s) you need.
