APPLICATIONS
🔹 Offline or depressurized pipeline testing
🔹 Maintenance, inspection, and fabrication environments
🔹 Utility, process, and pipeline repair operations
🔹 Hydrostatic testing of weld joints and fittings
🔹 Pre-commissioning validation
🔹 Ideal for safe, repeatable tests in controlled conditions.
KEY FEATURES & BENEFITS
🔹 Dual-seal configuration isolates the weld zone precisely.
🔹 Compact and lightweight for easy handling and quick installation.
🔹 Uses minimal water volume for localized pressure tests (< 1 gallon).
🔹 Aluminum/steel hybrid construction — strong yet portable.
🔹 Ideal for depressurized or workshop testing.
🔹 Reduces downtime and testing costs compared to welded closures.
🔹 Custom sizes and seal materials available on request.
Result: precise testing, simplified setup, and engineered reliability for every weld.

HOW IT WORKS
- Insert the DB-WELD™ plug into the pipe bore beyond the weld area.
- Tighten the compression nuts to expand the dual seals and create the isolation zone.
- Inject water through the test port to pressurize between the seals.
- Hold pressure for the required duration and monitor the test gauge.
- Release pressure and remove the plug. no cutting, no welding, no rework.
Fast installation, low-volume testing, and consistent performance every time.
