EZ Purge® Slip Blinds
Safely Purge While Preventing Equipment Damage from Traditional Methods
USA Industries, Inc.'s EZ Purge slip blind replaces an unsafe and outdated practice for line purging applications that uses a slip blind and several spacers sandwiched between the blind and the gapped flange. Although this procedure can be used to create a purging area, several problems exist that will lead to unsafe practices and/or damage to the operators equipment.
The purge blind creates an "stand off" area at the flange site, that allows for line purging. It seals evenly, resulting in no damage to the flange gasket surfaces associated with using wedges, tubing, or other metals to create space between the blind and flange.
- Safer, quicker and easier than traditional purging methods
- Prevents damage to flanges from makeshift spacers
- Unique handle quickly identifies blind as a Purge Blind
Frequently Asked Questions
Our standard thickness is 1/2" with 1/4" milled slots.
We can manufacture hydrotest EZ Purge blinds that will withstand hydrotesting, but our standard blinds are designed for isolation only. Please let us know at the time you're ordering, and we can increase the thickness of the non-purged side to withstand hydrotesting.
Yes, but if you want them much deeper, we will suggest the total thickness of the blind to be increased.
Carbon steel blind handles are painted to match the standard flange rating colors. All of our slip blinds are indent marked and polished to smooth edges.
We have designed our EZ Purge blind to have an effective purge area of 50% to prevent damage of the gasket surface.
Yes. Our proprietary design allows you use this blind with or without a gasket on the purge side. This will not affect the amount of purge flow.
Yes. We can do both machined 125-250 rms finishes and RTJ male or female surfaces upon request.
