Key Benefits

Discover the key advantages that make our services reliable, efficient, and optimized to your project needs.

Minimized downtime

Tests only the weld. Localized testing lowers fluid use and significantly reduces maintenance project timelines.

High-Pressure Capability

Enables welds to be subjected to pressures up to 4,500 psi, providing confidence in performance and long-term reliability.

Reduced Wastewater

Our tools make it possible to achieve significant reduction in wastewater - just 1/4 gallon of water required for a 24" test

Versatile Tools

Works in any orientation. Covers multiple pipe schedules and diameters with one tool - even in elbows and tees.

How It Works

Tool insertion and positioning

Hydratight places the in-line tool around the weld or section to be tested or isolated.

Seal engagement

Twin seals create a secure, vapor-tight barrier or define a localized test area.

Localized pressure testing

The isolated section is pressurized to verify weld integrity without affecting the rest of the system.

Results verification

Technicians confirm that welds meet safety, performance, and compliance standards.

Safe maintenance support

The barrier allows hot work or modifications to proceed with minimal risk.

Tool removal and reuse

After testing, the tool is removed and ready for future deployment.
