• 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

• hose structure :

internal tube: particular polymer engineering plastic as inner sealing tube

internal rubber liner: hnbr based inner sealing elastomer, which is good f fluid with h2s, oil resistance, crosion resistance, high temperature resistance, gas permeation resistance

breaker layer external protection layer: high tension textile fabric

reinfcement f maj pressure withst: high strength steel cable

fire shield layer: glass fiber cloth

cover: neoprene rubber based cover layers, fire resistance, wear resistance, oil resistance, ozone & ageing resistance, uv resistance which is applicable f critical marine environment
