2 kelly hose in stock

Kelly hose is used to connect the standpipe to the swivel. It allows the drill string to be raised and lowered while the drill fluid is pumped through it. Kelly line usually contains two layers of plated steel cables to reach 5000 psi operating pressure. Inside tube is made of special NBR to improve abrasion and corrosion capability. Rubber cover is compatible with the ozone, sunlight and oils for a long time. It is supplied with multiple end fittings – API flanges, threads, butt-welded union and other as specified.

Kelly drilling hoses are big inside diameter (3" to 4" ID) high pressure flexible lines used to between the standpipe and the swivel. This flexible piping permits the kelly to be raised and lowered while drilling fluid is pumped through the drill string. The simultaneous lowering of the drill string while pumping fluid is very important to the drilling operation.

Rotary drilling hose is mainly used for conveying water-based or oil-based mud and other fluids in the working temperature of -30 °C to +82 °C. It is often used for oil fields, cement repairing, geological exploration and water conveyance for coal excavation. It is composed of three parts: tube, reinforcement and cover. The tube is made from NBR, which is resistant to abrasion, corrosion and oils. The reinforcement is made from 2-8 layers of high tensile and high strength spiraled steel wire, making the hose have solid structure and resistant to high pressure. The cover is made from high quality synthetic rubber, mainly chloroprene rubber, making the hose resistant to abrasion, corrosion, cut, weather, ozone, aging and sunlight. The hose has longer service life as a result.

Dongying ROBUST offers every type and style of rotary drilling rubber hose. Compare the various drilling and hydraulic fracking benefits to determine the best choice for your application.

MAIN APPLICATION:The rotary/drilling hose is used in oil drilling industry, bore hole operation and washing, used on drilling rig for deliveringpetroleum based fluid: water,cement, mud

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.

A large-diameter (3- to 5-in inside diameter), high-pressure flexible line used to connect the standpipe to the swivel. This flexible piping arrangement permits the kelly (and, in turn, the drillstring and bit) to be raised or lowered while drilling fluid is pumped through the drillstring. The simultaneous lowering of the drillstring while pumping fluid is critical to the drilling operation.

High Pressure Drilling Rotary Hoses is used in drilling and exploration work. Suitable for hydraulic fluids, such as hydraulic oil, fuel oil, lubricants, emulsion, glycol and water.Drilling hose is also used to adjust the installation mistake between drilling pipe line and stand pipe to avoid shake. To transmit high pressure oil or water based mud.

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