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 downstream 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. (One of our refinery customers reports that it pays for itself one-quarter of the way through the first use!) Each 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.
