oilfield term 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.

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.

Reinforcing our capability to meet the growing demand forLarge Diameter Hose (LDH), JGB Enterprises, Inc. has decided to expand our production capabilities to include 12” crimping.

With our continued development and support of the energy exploration market, JGB Enterprises, Inc. has invested in the Techmaflex PES-500 Large Bore Hose Assembly Machine.

We feel this investment will lead the energy exploration market to the next level. We also look forward to this investment opening more opportunities in markets where the need for safety of crimped large diameter hoses exists.

Onshore and offshore, today"s drilling environments demand the most advanced products, superior performance, and excellent service. Oil field hoses consists of High Pressure hoses, Rotary, Kelly, Vibrator, and Mud Pump hoses, Cementing hoses, Choke and Kill hoses, Blow Out Preventer (BOP) hoses, and Petroleum and Fuel Transfer hoses.

High pressure oil field hoses range from 2" ID up to 5" ID with a wide range of available end connections. These hoses are built strong and are designed to last.

Choke hoses and kill hoses are commonly grouped together as Choke & Kill hoses. These hoses are usually 2" to 3-1/2" ID armored hoses designed to survive those critical moments when a well experiences trouble. More dangerous environments commonly call for fire rated Choke & Kill hoses which can survive even longer if things really get out of hand.

Rotary drilling hoses which are commonly referred to as Kelly Hoses are used on the drilling rig as high pressure, flexible rubber, steel reinforced hoses used to connect the standpipe to the swivel or top drive. Made of heavy duty rubber and steel cables the rotary hose flexible piping allows the Kelly, the bit, and drill string to be raised and lowered while the drilling fluid is pumped through. The lowering of the drill string while pumping fluid is crucial to the drilling process and a durable reliable hose is a most. Usually made in diameters of 2", 2-1/2", 3", 3-1/2", and 4" ID"s and in lengths starting at 4ft vibrator hoses all the way up to 91ft.

This is the brief explanation of a Kelly rotating system on the rig. Kelly rig is on an old style rigs and  nowadays it is mostly used on land operations. For offshore operation, a top drive system is used instead.

The upper end of the drill pipe is screwed onto the saver sub. The saver sub is used to protect and minimize wearr and tear on the threads at the bottom of the Kelly. The Kelly is about 40 ft in length with a square or hexagonal shape and it is hollow throughout in order to transport the drilling mud.  Kelly moves freely through a Kelly bushing even though the drill stem is rotated.

A Kelly cock valve is located at the top of a Kelly and it is a safety valve which can be closed to stop back pressure from coming back to damage other surface equipment.

A swivel attached to the hook does not rotate, but at the bottom part it supports the Kelly which is being rotated while drilling.  Drilling mud is pumped from a mud pump to a stand pipe manifold, Kelly hose and then to a gooseneck connection at a swivel.

A rotary table rotates a Kelly bushing and it simultaneously rotates a Kelly and a drill string and a drill bit. A rotary table has two main functions. The first one is to provide rotation to a drill stem and a bit and the second function is to hold slip in order to support the weight of a drill stem when it is not connected to a Kelly.

A master bushing severs its function as a rotary motion transmission from a rotary table to a Kelly. Additionally, it is a link between a slip and a rotary table.

A Kelly bushing (some people call “rotary Kelly bushing”) engages a master bushing via four pins and rollers inside a Kelly bushing to allow a Kelly to move up or down freely while it is rotated or in a static mode.

New rubber compounds, higher working pressures and temperatures, stricter environmental and safety regulations – all make hose selection a challenge. At Gates, we make it easy. That’s because our line of high pressure oilfield hoses are made with the demands of today’s drilling methods in mind. From rotary-vibrator drilling hoses to choke and kill hoses, find oilfield hoses built tough to handle the pressure.

Parker"s Series 7234 Wildcatter Oilfield Slim Hole Rotary Drill Hose is compatible with many oilfield media and provides excellent high pressure service across multiple drill site applications. The hose incorporates high pressure and high temperature capabilities and features a cover that is resistant to abrasion, oil and weathering to provide maximum performance. Series 7234 is qualified with permanent crimp couplings for a safe and secure connection and provides robust service life in challenging applications.

• Couplings attached with bands or clamps may reduce the working pressure of the hose assembly to less than the maximum rated working pressure of the hose. Refer to NAHAD Industrial Hose Assembly Guidelines
