Flange Weld Testers

Introducing the Flange Weld Testers, designed to provide integrated solutions to piping problems by allowing you to purge, weld, and test flange connections with a single tool. These testers are essential for efficient and safe pipeline maintenance and repair.

Key Features:

• Fast and Easy Installation: Simplifies the process of installing and testing flange connections, reducing downtime.
• Efficient Pipe Repairs: Enables faster pipe repairs and retrofits, improving overall productivity.
• Reduces Non-Destructive Examination (NDE): Minimises the need for additional NDE processes.
• Minimal Water Use: Requires a minimal amount of water for testing, reducing handling and waste.
• Safety Factor: Designed with a minimum 1.5:1 safety factor for reliable operation.
• Upstream Monitoring: Equipped with a center port for upstream monitoring, ensuring accurate testing and safety.

Maximum Test Pressures:

• 150 ANSI Flange Class: Up to 450 psi (30.9 Bar)
• 300 ANSI Flange Class: Up to 1,125 psi (77.2 Bar)
• 600+ ANSI Flange Class: Consult Patriot International for higher pressure ratings

Functionality:High Lift Flange Weld Test Plugs allow you to monitor upstream conditions, isolate and purge the weld area, perform the weld, and hydro test the weld joint to ANSI B16.5 requirements using only one tool. This eliminates the need for blind flanging upstream, vacuum trucks for evacuating the line, and X-raying. Each flange test requires a minimal amount of water, avoiding the need to fill the entire line.

Specifications:

• Flange Sizes: From 3/4” (DN20) to 24” (DN600)
• Pipe Schedule and Clearance:
  • Sizes available for schedules 40, 60, XS, and STD
• Ports:
  • Vent & Fill Port NPT sizes vary by flange size (from 1/8” to 3/4”)
• Dimensions and Weight:
  • Detailed dimensions and weights are provided for each flange size and rating, ensuring precise fitting and handling

Applications:

• Isolating Sections for Maintenance: Ideal for isolating sections of pipelines during maintenance and repair.
• Safety Assurance: Ensures safe and reliable testing of flange welds to prevent leaks and failures.
