High Lift Flange Weld Test Plug

Monitor upstream conditions, isolate and purge the weld area, perform the weld, and hydro test the weld joint with one easy tool. No blind flanging upstream, no vacuum truck for evacuating the line, and no X-raying. Each test requires a minimum amount of water, no need to fill the entire line. You will use less water and minimize your environmental impact. Operating pressures to ANSI B16.5 requirements.

Test Pressure
150# 450 PsiG 31.0 BarG
300# 1125 PsiG 77.6 BarG
600# 2250 PsiG 155.1 BarG

Size Range
3/4” to 24” NPS (DN20 to DN600)
Higher flange classes & pressures available

Standard Seal Material
Urethane**

Features

• Designed to function in four distinct ways: as a purge dam, weld fixture, test plug, and a weld isolation plug

• Flange-to-pipe welds are tested without needing
to pressurize the entire system

• Ported center shaft allows for upstream monitoring

• Segmented compression tube design allows for the adjustment of the distance between the flange and seal

• ASME PCC-2 Type III testing device¹
