kelly hose specification 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.

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.

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.

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.

Armored hose assemblies with flame resistant cover withstand minimum 1300°F (+700°C) flame temperature at working pressure for 5 minutes without failure.

Accessories such as API 16D quick connector, self-sealing union and exterior armor to protect hoses against extreme environmental damage are available upon request.
