Oilfield Rotary Drilling Hose Choke and Kill Hose
10,000psi W.P. 15,000 psi Test-22,500 psi Minimum Burst   
 

Certification/Standards: 

API Spec 16C--ISO 14693

Recommended For: 

Flexible hose between the riser and manifold or around the ball joint of offshore drilling rigs, specially designed to withstand high pressure.

Tube: 

Modified Nitrile. Black. Resists abrasion, corrosion, oil, and up to 20% H2S.

Reinforcement: 

Multiple layers of textile fabric and steel cable, with one layer middle rubber placed between cable layers.

Cover: 

Fire resistant rubber cover, stainless steel armored to handle abrasion, corrosion, cutting, gouging, oil and weather.

Swaged couplings. Full range of couplings are available, such as hammer unions, flanges, camlock, male thread, etc.

Temperature: 

-4℉ to +200℉ (-20℃ to +93℃) continuous service.

Options: 

Accessories such as safety clamps and hose lift eyes are available upon request.

Test:  

Each hose is tested at 15000psi for 15 minutes. Pressure test graph, test certificate and letter of conformance are issued for each hose.

Application: 

The choke & kill line works as the connection part when drill platform, semi-submersible drilling vessel or drilling vessel moves relatively and for adjustment of the installation variance of the drilling rig. It transfers oil, gas, mud and other high pressure media. It is mainly used for connection of inner and outer high pressure choke and kill hose and as flexible connection between mud & gas separator and choke manifold.
