Combined with our pipe cutting, sever and beveling field services, we are able to provide a complete turnkey pipe isolation and weld testing service. We can manage the entire project and get your equipment back in service safely with minimal downtime.

Turnkey Plug Isolation
& Weld Testing

The need to add new flanges or replace existing flanges and butt-welds to a pipe system is a part of capital expansion or general maintenance. Traditional solutions such as full line pressure test or using mud plugs are problematic and expensive. We have replaced these messy and time consuming procedures with a simple and convenient hydrostatic testing system.

Isolate the Line

Using a double block and bleed plug we are able to monitor and isolate potential explosive vapors from hot work areas.

Test the Weld

Once welding is complete, a hydrostatic test using a minimum amount of liquid can be performed to verify the integrity of the welds.
