kelly hose drilling pricelist

Flexible drilling rubber hoses play an important role in petroleum extraction. They should suffer high operating pressure, extreme operating temperature, abrasion and other inferior elements. Our special compounded synthetic rubber has been proven an effective and economical way to reject these problems. All our oilfield drill hoses are manufactured as API 7K or other related specifications.

Steel cable reinforcement loads most working pressure up to 15,000psi. The wires are usually zinc-plating or copper platting to improve steel wire resistant against rust and corrosion. Due to the thick reinforcement, the hoses should be handled or stored in correct way to avoid kicking or crushing. They will substantially decrease their rated operating pressure.

Rotary hose, Kelly hose, cement hose, mud hose, jumper hose and vibrator hose and choke & kill hoses are the most popular oilfield rubber hoses. They convey high-pressure drilling fluid from one place to another. Many end fittings are provided to satisfy different applications. Most end fittings are made according to API standards. Special order is also available.

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.

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.
