Product Features• Safer, quicker and easier than traditional practices
For line purging applications, past practice has been to use a slip blind and number of spacers sandwiched between the blind and the gapped flange. While this procedure can effectively be used to create a purging area, a number of problems exist which can lead to unsafe practices and/or damage to equipment.
USA Industries' new EZ Purge® Blinds can help eliminate all of those problems. The EZ Purge blind creates a "stand off" area at the flange site, allowing for line purging. The EZ Purge blind seals evenly, eliminating damage to flange gasket surfaces often associated with the dated practices of using wedges, tubing, or other metals to create space between the blind and flange.
EZ Purge Blinds are easily identifiable due to a uniquely shaped and color coded handle. They can be made to any specifications requested. The current standard we use is a 1/2" thick isolation blind with a 1/4" deep channel milled at either 3/4", 1", or 1 1/2" widths depending on the blind size. The ratio of gasket area versus purge area is approximately 50% to allow for proper sealing force distribution.
Blinds come standard in sizes from 1/2" to 96" and flange classes from 150# to 2500#. Unless otherwise specified, our Purge blinds are painted flat black and are stamped with their size & rating for ease of use. Custom configurations available to suit your specific purge flow requirements. In-stock orders are shipped the same day.
