Kill Hose

Flexible Choke & Kill Hose

API 16C Choke and kill line is an importance part in choke and kill system, which is an integral part of surface and subsea blowout prevention equipment.

1. This hose allows to pump fluid to the well when normal circulation through the drill string cant be employed;

2. Additionally the choke line and manifold provide a means of applying back pressure on the formation while circulating out formation fluid influx into the well bore following a kick;

3. Sour service
