Double block and bleed technology trough a single Hot-Tap:
Prostopp uses two independently manipulated plugging heads to seal your pipeline with the
possibility of bleeding the space between the two plugging heads.
This hydraulically activated isolation tool uses an energized seal which allows for one sealing element to cover multiple wall thickness per nominal pipe size and has no problem with ovality of your pipeline. The sealing elements can be used more than once.
ProStopp DS maximum isolation pressure is 285 psi (19 bar), and can be used in carbon steel lines for gas, liquid, or refined oil products at temperatures up to 100°C in sizes 4” – 12”.
