Choke and Kill Line Hose Used in Oil Drilling and Exploration

Choke and kill line hose is mainly used in oil drilling and exploration work. It is manufactured as the flexible connection between standpipe and rotary drilling swivel or between pump and rotary vibrator standpipe for mud suction at very high pressure. It is composed of tube, reinforcement and cover. The tube is usually used to transfer the abrasive, corrosive drilling mud and the cover is used to resist the damage caused by abrasion, corrosion, ozone and weather.

Choke and kill line hose can transfer mud safely at high pressure.

Choke and kill line hoses are packed in wooden boxes, making them easier to transport.

The details of choke and kill line hose:

• Structure: it is composed of tube, reinforcement and cover.
  • Tube: resistant to oil, abrasion, acids and alkalis synthetic rubber, principally nitrile rubber.
  • Reinforcement: multiple high tensile steel wire spiral layers.
  • Cover: resistant to ozone, abrasion, corrosion and weather synthetic rubber.
• Inner diameter: 2" - 4".
• Outside diameter: 99mm - 183mm.
• Working pressure: 34.5MPa (5000psi).
• Test pressure: 69.0MPa (10000psi).
• Min burst pressure: 103.5MPa (15000psi).
• Working temperature: -4°F - +200°F (-20°C - +93°C).

Our advantage:

• The working pressure of drilling hose is designed based on the maximum working pressure of drilling machine. The minimum burst pressure of drilling hose is 2.5 times as high as the working pressure. Therefore, even though the pump breaks down, the drilling hose will not burst.
• The tube of drilling hose is made from nitrile rubber, which can prevent the oil-based mud from permeating out of hose leading to the hose damage in the process of conveying the oil-based mud.
• Our drilling hose is manufactured with integral connectors and the connectors are resistant to pull-off, which can avoid the connectors falling off and hurting the workers in the process of pressure test. And this feature improves the pressure resistance and safety performance of drilling hose greatly.

Features:

• Resistant to high pressure.
• Fire-resistant.
• Heat insulation.
• Resistant to weather and ozone.
• Anti-corrosion.

The application of choke and kill line hose:

• Choke and kill line hose is used as flexible connection in the choke manifold and kill manifold system.
• It is used in oil drilling and exploration work.
• It is used for the adjustment of installing error between the drilling pump and the rotary drilling standpipe.

Choke and kill line hose can be used as the flexible connection of the choke manifold and kill manifold system.
