Isolation & Inline Weld Testing
Traditional isolation procedures for weld testing demand lengthy schedules and unmitigated risks. Numerous blind flanges, skillets, and air movers are required in order to clear the asset of harmful vapors, where even with the use of air movers controlling vapor gases are unpredictable. These risks coupled with project constraints make traditional isolation and weld testing procedures outdated.
Inline isolation tools advance safe construction tasks related to welder safety, pressure testing, and weld seam integrity testing. Through the use of patented mechanical functionality, isolation and inline weld testing technology monitors seal integrity and safely vents vapor gases away from the immediate hot work zone. By mechanically performing a double block and bleed upstream of the planned hot work area, a set of compression bolts seal the tool and the internal diameter of the pipe asset. Water and other mediums are then inserted into the annulus of the tool and pressurized to ensure an adequate seal on the desired cavity area. In the duration, pressure is monitored to ensure seal integrity. Once confirmed, vapors are allowed to exit the isolation and inline weld testing tool prior to initiating hot work. This procedure is replicated for weld test integrity, eliminating the need for performing a pressure test on the entire asset.
Understanding that facility work areas demand schedule and asset friendly solutions, isolation and inline weld testing tools empower fast response, minimize multiple contractors onsite, and deliver proven and safe pipe cavity operations.
