kelly hose specification pricelist

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.

Drilling hose/ Rotary Hose / kelly hose, made according to API 7K standard, applies for flexible hose connection between the top of oil drilling, well cementing, work-over and down hole servicing operation. 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.

High pressure rubber mud hose, vibrator hose and drilling hose consist of 4 layers. The framework is made of steel wire rope with high strength.The inner seal layers adopts synthetic rubber which is weather,oil and heat resisting.The material of external protective layer for rubber mud, vibrator and drilling hoses is also made of synthetic rubber which effectively resists aging,oil and abrasion.Besides, additional layer for fireproofing can be added according to customer request.

the steel wire winding drilling hose consists of the inner rubber layer, the inner glue protection layer, the medium glue layer, the wire winding reinforced layer and the outer rubber layer.

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.

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.

The kelly rotary drilling hose is 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. Kelly Rotary drilling hoses are used in oil fields, well cementing, well repairing, geological explorations, small drilling machine, and water

Flexible connection between standpipe andswivel (Rotary Drilling) or betweenpump and standpipe (Rotary Vibrator) for pumping mud at extra high pressure inoil drilling and exploration work. Meets the high demands of directional drillingand down linking with negative pressure pulses and elevated temperatures. Thishose can also be used as a Motion Compensator hose for stabilization of rotarydrilling and pumping equipment against vertical wave action on offshore drillplatforms. The Motion Compensator hose is not recommended for phosphateester fluids.
