What separates USA Industries blinds from the competition — built into every piece.
Why Our Blinds Are Different
We are the actual manufacturer, not just a reseller. Since 1982, using advanced CNC plasma and waterjet machines, each blind is crafted with engineered symmetry, clean edges, fresh paint (carbon steel), marked or stamped, and color-coded handles for easy flange rating identification. Also, our blind solutions are crafted from top-grade, American milled alloys, including carbon steel, stainless steel, and other specialized materials known for their strength, durability, and corrosion resistance.
Moreover, unlike others who may claim this, USA Industries has the largest stock for immediate delivery and in-house production.
USA Industries' EZ Purge Slip Blind offers operators a safe and modern alternative to the outdated line purging practices involving a slip blind and spacers, which poses safety risks and equipment damage. The EZ Purge slip blind creates a "standoff" area at the flange site for line purging. It seals evenly, preventing damage to flange gasket surfaces caused by wedges, tubing, or other metals used to create space.
A Purge Blind enhances safety and system integrity by:
- Isolating Pipeline Sections: Prevents leaks, spills, and contamination during maintenance.
- Facilitating Welding: Creates a controlled environment for high-quality welds using inert gases.
- Maintaining System Integrity: Allows inspections and repairs without disrupting operations.
- Ensuring Accurate Pressure Testing: Seals sections to prevent leaks and pressure loss.
- Regulatory Compliance: Supports adherence to safety and environmental standards.
