Weld & Isolation Tests

The Small Bore and Standard Bore Isolation and Test Plugs are designed to provide an isolation barrier on localized field repairs and modifi­cations, designed to isolate, monitor and vent hydro­carbon vapours to a safe area. SPR’s plugs incor­porate unique features such as engineered seal geometry and proprietary material blends to make it the most appli­cation-efficient tool on the market while keeping safety the number one goal.


SPR’s bore tools are schedule-specific for pipe sizes ranging from 0.75” – 42”. Each tool can be easily adapted with gripper jaws to make them back pressure rated up to 1,500 PSI.
