Petroleum Drilling Hose

API 7K Rotary drilling rig hose/Mud hose/Vibrator hose

5,000psi W.P. – 10,000 psi Test-12,500 psi Minimum Burst

Certification/Standards:

API Spec 7K-ISO 14693-NACE MR0175

1.Purpose:

suitable for rotary hose for flexible connection between the top of the drilling riser and the vertically movable water faucet in the oil drilling and mud delivery systems,and for the adjustment of installing error between the drilling pump line and the riser for the connection and vibration isolation.

It is also suitable for delivering in large quantity at high pressure the water-based or oil-based mud with the min. aniline point at 66℃ pumped out of rotary drilling equipment.Moreover, it resists to corrosion from hydrogen sulfide and delivers water, oil,mud and other high-pressure media in borehole operation in oil field.

2.Construction:

It made of inner sub or stainless steel armor inner tube ,carbon fiber reinforce sub,middle sub,steel wire reinforce sub ( steel catenarian line reinforce sub ),and carbon fiber outer sub.

3.The product is classified into steel wire reinforcing type and steel link line reinforcing type.

4.Applicable standard: API Spec7K SY/T5469

5.API emblem practical license Numbers: 7K

for:Commonly used in drilling,cementing,work over services as flexible connector between standpipe and

Application: Used as Flexible connection between standpipe and swivel (Rotary Drilling) or between pump and standpipe (Rotary Vibrator) for pumping mud at extra high pressures in oil drilling and natural gas exploration work (including 50D, 70D).

Temperature Range: -30°C~ 120°C, or manufactured upon customers' requirements

Hose Reinforcement:2~ 6 layers spiraled by single high-strength steel wire, and rubber as a binder to make the layers into one complete and sound construction

Lining: Principally NBR constructed, featuring oil-resistant, abrasion-resistant, acid, alkali & flame resistant.

Hose Cover: Primarily CR fabricated, featuring oil-resistant, abrasion-resistant, weatherproof and anti-ageing

Coupling Type: NKT 60X2.5 , HAMMER UNION 1502 , BSPT 4"

Reference Standard: API Spec 7K,ISO 6807

Flexible connection between standpipe and swivel (Rotary Drilling) or between pump and standpipe (Rotary Vibrator) for pumping mud at extra high pressure in oil drilling and exploration work. Meets the high demands of directional drilling and down linking with negative pressure pulses and elevated temperatures. This hose can also be used as a Motion Compensator hose for stabilization of rotary drilling and pumping equipment against vertical wave action on offshore drill platforms. The Motion Compensator hose is not recommended for phosphate ester fluids.

Tube:HNBR rubber. 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:Modified Nitrile. Black. Specially designed Ultra abrasion cover is resistant to abrasion, corrosion, cutting, gouging, oil and weather.

Couplings: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, hose lift eyes and stainless steel armor are available upon request.

Test:Each hose is tested at 10000psi for 15 minutes. Pressure test graph, test certificate and letter of conformance are issued for each hose.

Test: Each hose is tested at 10000psi for 15 minutes. Pressure test graph, test certificate and letter of conformance are issued for each hose.

Strong quality control team, advanced laboratory.

Before the mass production, test each batch of raw material.

After the production, test each hose to guarantee a 100% qualification.

Each hose tested at 2 times of working pressure.

We do everything possible to supply good quality goods for our customer.

After finishing the hose production, we will pack the hose.

In general, the packing will use woven bag and plastic film.

Special packing is available according to customers' requirements
