Flexible Choke & Kill Hose JYG-SZ

• application:

api 16c choke kill line is an imptance part in choke kill system, which is an integral part of surface subsea blowout prevention equipment. 1. this hose allows to pump fluid to the well when nmal circulation through the drill string cant be employed; 2. additionally the choke line manifold provide a means of applying back pressure on the fmation while circulating out fmation fluid influx into the well be following a kick; 3.sour service

• stard: api spec 16c
