drilling kelly hose in stock

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 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.

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.

The main advantage of a kelly hose is that it helps you move water from one point to another without much struggle. Hose pipes are also versatile and can be used for various activities in your home or at your workplace. Moreover, rubber horse pipes are durable since rubber is a strong material. This means that you won’t need to replace it often. Additionally, rubber hoses are less prone to cuts and abrasions. Another advantage of this hose pipe is that it absorbs shocks and vibrations. Also, there is no need for specialized bending or brazing since it can bend easily. Lastly, it reduces pressure surges and lubricates itself.

When buying a kelly hose, there are several factors that you need to consider, including length, couplings, thickness, and price. The length of the kelly hose is an important factor to consider. If you are taking the water to the furthest corner of your compound, consider getting a longer pipe for convenience. Also, if you are watering a large garden, a longer pipe will serve you better. Couplings or horse pipe fittings are also another important consideration. These are the accessories that help you connect your pipe to the water source. They can either be made from brass or plastic. Some people prefer plastic couplings since they are lightweight, but they can break easily. Brass fittings are heavier but long-lasting. Lastly, consider the thickness of the pipe. This refers to the number of layers used to make the kelly hose. Thickness determines the weight of the pipe and ease of bending.

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.

Meets the severe demands of today’s drilling methods including directional drilling, pressure pulses and elevated temperatures. Tube is designed to handle abrasive, corrosive and oil based drilling muds. The cover is designed to handle external damage from abrasion, corrosion, gouges, oil and weather.

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.
