Abstract

Rørplugg (10) for å tette et rør (12) ved et valgt sted har et perifert system av glidere (18). Det første trinn med å feste pluggen (10) på plass, blir gli- derne (18) beveget i forhold til skrå overflater (22) for å komme i kontakt med det indre av rørledningen (12). I et annet trinn blir gliderne (18) låst i den stillingen ved oppstrøms rørled- ningstrykk som viser på et stempel (10) for å forårsake radial utvidelse av stemplene (26) via et overknekksledd (40)
