These plugs have a Urethane seal.

Steam, Sniff, Purge, Weld and Test - All With The Same Plug.  For quickly isolating and hydrostatically testing the weld joint of any welded flange-to-pipe connection.

The new and approved "High Lift" seal design permits greater seal to pipe clearance and higher seal expansion.  This means the plug will easily pass over weld penetration.  Grinding out deep root penetrations is eliminated.

This plug will reduce 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.  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.
