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 E-Z Purge blinds can help eliminate all of those problems. Our
Purge Blinds are easily identifiable and can be made to any specifications requested.
The current standard we use is a 1/2” thick 516 Gr70 slip 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.
