High Lift Flange/Weld Test Plug



High Lift Flange/Weld Test Plug

Purge, Weld, and Test Flange Connections with the Same Plug

All Flange Styles Improved Seal-to-Pipe Clearance

EST reduces the expense, downtime delays, and waste disposal problems associated with conventional flange-to-pipe weld testing.

Our High Lift Flange/Weld Test Plug lets you 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. Just a simple, rock-solid tool that saves time and money every time you use it.

Each flange test requires a minimum amount of water, and there’s no need to fill the entire line.

You’ll use less water,and minimize your environmental liabilities.
