Relying solely on stopples to guard against upstream vapors and pressure upsets can put employees at risk when working with live lines. If complications at the stopple occur, detection needs to be immediate… as there is zero room for error. Add an extra layer of protection by combining a hot tap/stopple with EST Group’s GripTight® Isolation Plug to complete tie-in work safely.
We’ve Got Your Back
So what makes our GripTight Isolation Plug the go-to solution when isolating, welding, and testing live lines for tie-in work? It’s the grippers! We integrated our GripTight® gripper technology with the functionality of a conventional Double Block and Bleed Plug to minimize the risk of accidental blowouts/expulsions due to unexpected upstream vapor and pressures.
- Test Pressure: Up to 2250 PsiG (155 BarG) between the seals
- Upstream Monitoring: Up to 1500 PsiG (103 BarG)
- Size Range: 3/4” to 48” NPS (DN20 to DN1200) - larger sizes available upon request
- Standard Seal Material: Urethane – Additional materials available upon request
- Dual Port Design: creates a positive pressure barrier between the seals, safely isolating hot work from any residual upstream gases
