Purge, Weld, and Test Flange Connections with One Plug
Reduce the expense, downtime delays, and waste disposal problems associated with conventional flange-to-pipe weld testing with EST Group’s High Lift Flange/Weld Test Plug.
High Lift Flange Weld Test Plugs allow you to monitor upstream conditions, isolate and purge the weld area, perform the weld, and hydro test weld joint to ANSI B16.5 requirements using only one tool. No blind flanging upstream, no vacuum truck for evacuating the line, and no X-raying. Each flange test requires a minimum amount of water, eliminating the need to fill the entire line. Use less water and minimize your environmental impact!

Features
- Improved seal-to-pipe Clearance: plug can be easily installed and removed even where there is severe weld protrusion
- Flange-to-pipe welds are tested without pressurizing the entire system
- Ported center shaft allows for upstream monitoring
A flange hydro test plug allows you to monitor upstream conditions, isolate and purge the weld area, and perform the weld with only one tool.
