WHY YOU NEED TO USE A PURGE BLIND

USA Industries offers the The EZ Purge slip blind is a safe and modern alternative to the outdated line purging practices involving a slip blind and spacers, which poses safety risks and equipment damage.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.

Safety is enhanced by a purge blind, which minimizes the risk of accidents or environmental hazards during maintenance or repair activities by isolating sections of the pipeline. It helps control the release of hazardous substances or gases, reducing the potential for leaks or spills.
During maintenance, repairs, or modifications of piping systems, a purge blind prevents contamination by sealing off sections of the piping where work is being done. This ensures that foreign materials such as dirt, debris, or contaminants do not enter the system.
Facilitating welding operations, a purge blind creates a controlled environment during welding or fabrication processes by sealing off the section of the pipeline where welding is taking place. This allows for the purging of the pipe with inert gases such as argon to prevent oxidation and ensure high-quality welds.
Maintaining system integrity, a purge blind isolates specific sections for inspection, testing, or repair without affecting the rest of the system. This is particularly crucial in industries where pipeline integrity is critical, such as oil and gas, chemical processing, and pharmaceuticals.
During pressure testing procedures, a purge blind is used to isolate sections of the piping system for testing purposes. By sealing off the area being tested, it ensures accurate pressure readings and prevents leaks or pressure loss from affecting the results.
To comply with regulations, many industries adhere to strict regulations governing the maintenance, repair, and testing of piping systems. Using a purge blind as part of these processes helps ensure compliance with regulatory requirements and industry standards for safety and environmental protection.
