definition of kelly hose supplier
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.

A rotary hose is also used as a means of permitting the kelly to be either raised or lowered through the drilling process while also allowing the drill bit to be raised with the drillstring. For this reason, it is also often referred to as a “kelly hose.”
Rotary hoses also function during the process that allows the drilling fluid to be pumped through the hose when the bit and drillstring are raised and lowered. This process is imperative in the completion of the drilling process.
These rotary vibrator hoses are made up of the Gates range of Black Gold hoses that meet the severe demands of today’s drilling methods including directional drilling, pressure pulses and elevated temperatures.
A rotary/pumper hose is used in oil well drilling. It acts as the crucial instrument in the connection being made between the standpipe and the swivel.

Rotary Drilling/Pumper hose is mainly used for conveying water-based or oil-based mud and other fluids in the working temperature of -30 °C to +82 °C.
The reinforcement is made from 2-8 layers of high tensile and high strength spiraled steel wire, making the hose have solid structure and resistant to high pressure.
The cover is made from high quality synthetic rubber, mainly chloroprene rubber, making the hose resistant to abrasion, corrosion, cut, weather, ozone, aging and sunlight.
A Kelly hose (also known as a mud hose or rotary hose) is a flexible, steel reinforced, high pressure hose that connects the standpipe to the kelly (or more specifically to the goose-neck on the swivel above the kelly) and allows free vertical movement of the kelly while facilitating the flow of drilling fluid through the system and down the drill string.
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.

The space around a pipe in a well bore, the outer wall of which may be the wall of either the bore hole or the casing; sometimes termed the annular space.†
One or more valves installed at the wellhead to prevent the escape of pressure either in the annular space between the casing and the drill pipe or in open hole (for example, hole with no drill pipe) during drilling or completion operations. See annular blowout preventer and ram blowout preventer.†
A blowout preventer that uses rams to seal off pressure on a hole that is with or without pipe. It is also called a ram preventer. Ram-type preventers have interchangeable ram blocks to accommodate different O.D. drill pipe, casing, or tubing.†
A heavy, flanged steel fitting connected to the first string of casing. It provides a housing for slips and packing assemblies, allows suspension of intermediate and production strings of casing, and supplies the means for the annulus to be sealed off. Also called a spool.†
A pit in the ground to provide additional height between the rig floor and the well head to accommodate the installation of blowout preventers, ratholes, mouseholes, and so forth. It also collects drainage water and other fluids for disposal.†
The arrangement of piping and special valves, called chokes, through which drilling mud is circulated when the blowout preventers are closed to control the pressures encountered during a kick.†
A centrifugal device for removing sand from drilling fluid to prevent abrasion of the pumps. It may be operated mechanically or by a fast-moving stream of fluid inside a special cone-shaped vessel, in which case it is sometimes called a hydrocyclone.†

A small enclosure on the rig floor used as an office for the driller or as a storehouse for small objects. Also, any small building used as an office or for storage.†
The hoisting mechanism on a drilling rig. It is essentially a large winch that spools off or takes in the drilling line and thus raises or lowers the drill stem and bit.†
The cutting or boring element used in drilling oil and gas wells. Most bits used in rotary drilling are roller-cone bits. The bit consists of the cutting elements and the circulating element. The circulating element permits the passage of drilling fluid and uses the hydraulic force of the fluid stream to improve drilling rates.†
The heavy seamless tubing used to rotate the bit and circulate the drilling fluid. Joints of pipe 30 feet long are coupled together with tool joints.†
A wire rope hoisting line, reeved on sheaves of the crown block and traveling block (in effect a block and tackle). Its primary purpose is to hoist or lower drill pipe or casing from or into a well. Also, a wire rope used to support the drilling tools.†
The heavy square or hexagonal steel member suspended from the swivel through the rotary table. It is connected to the topmost joint of drill pipe to turn the drill stem as the rotary table turns.†
A device fitted to the rotary table through which the kelly passes. It is the means by which the torque of the rotary table is transmitted to the kelly and to the drill stem. Also called the drive bushing.†

Shallow bores under the rig floor, usually lined with pipe, in which joints of drill pipe are temporarily suspended for later connection to the drill string.†
A series of open tanks, usually made of steel plates, through which the drilling mud is cycled to allow sand and sediments to settle out. Additives are mixed with the mud in the pit, and the fluid is temporarily stored there before being pumped back into the well. Mud pit compartments are also called shaker pits, settling pits, and suction pits, depending on their main purpose.†
A diesel, Liquefied Petroleum Gas (LPG), natural gas, or gasoline engine, along with a mechanical transmission and generator for producing power for the drilling rig. Newer rigs use electric generators to power electric motors on the other parts of the rig.†

Wedge-shaped pieces of metal with teeth or other gripping elements that are used to prevent pipe from slipping down into the hole or to hold pipe in place. Rotary slips fit around the drill pipe and wedge against the master bushing to support the pipe. Power slips are pneumatically or hydraulically actuated devices that allow the crew to dispense with the manual handling of slips when making a connection. Packers and other down hole equipment are secured in position by slips that engage the pipe by action directed at the surface.†
A relatively short length of chain attached to the tong pull chain on the manual tongs used to make up drill pipe. The spinning chain is attached to the pull chain so that a crew member can wrap the spinning chain several times around the tool joint box of a joint of drill pipe suspended in the rotary table. After crew members stab the pin of another tool joint into the box end, one of them then grasps the end of the spinning chain and with a rapid upward motion of the wrist "throws the spinning chain"-that is, causes it to unwrap from the box and coil upward onto the body of the joint stabbed into the box. The driller then actuates the makeup cathead to pull the chain off of the pipe body, which causes the pipe to spin and thus the pin threads to spin into the box.†
A vertical pipe rising along the side of the derrick or mast. It joins the discharge line leading from the mud pump to the rotary hose and through which mud is pumped going into the hole.†
A rotary tool that is hung from the rotary hook and traveling block to suspend and permit free rotation of the drill stem. It also provides a connection for the rotary hose and a passageway for the flow of drilling fluid into the drill stem.†
The top drive rotates the drill string end bit without the use of a kelly and rotary table. The top drive is operated from a control console on the rig floor.†

Drilling hose also called Oilfield drilling hose, rotary drilling hose, is hollow, thin-walled, steel or aluminium alloy piping that is used on drilling rigs. It is hollow to allow drilling fluid to be pumped down the hole through the bit and back up the annul-us. It comes in a variety of sizes, strengths, and wall thicknesses, but is typically 27 to 32 feet in length (Range 2). Longer lengths, up to 45 feet, exist (Range 3).
Oilfield drilling hoses have found their wide application in the extraction of minerals such as oil & gas drilling. With the help of the drill pipe, a drilling mud is injected into the well at a very high pressure, most often technical water, hydrogel solution or clay-based solutions. The drill hose is also used between oil tankers and drilling wells in the sea. Drilling hoses can be used on stationary and mobile drilling rigs, for drilling wells in the sea.
The drilling rotary hose is suitable for flexible connection between the top of the drilling riser and the swivel which can move vertically. It resists corrosion of hydrogen sulfide and can deliver water, oil, mud high‐pressure media.
Rotary drilling hose is mainly used for conveying water-based or oil-based mud and other fluids in the working temperature of -30 °C to +82 °C. It is often used for oil fields, cement repairing, geological exploration and water conveyance for coal excavation. It is composed of three parts: tube, reinforcement and cover. The tube is made from NBR, which is resistant to abrasion, corrosion and oils. The reinforcement is made from 2-8 layers of high tensile and high strength spiraled steel wire, making the hose have solid structure and resistant to high pressure. The cover is made from high quality synthetic rubber, mainly chloroprene rubber, making the hose resistant to abrasion, corrosion, cut, weather, ozone, aging and sunlight. The hose has longer service life as a result.

A kelly hose is a piece of mining equipment. Specifically, it refers to a piece of equipment used in the mining of fluid or semi-fluid resources, such as oil and natural gas. The main purpose of a kelly hose is to allow the drill string to be raised and lowered at the same time that drill fluid is being pumped through it. This is important, as drill fluid is critical to the mining process.
In most cases, a kelly hose is classified as a large-diameter hose. This means that the inside diameter is usually between 3 and 5 inches (about 7.6 cm and 12.7 cm). This wide diameter allows for a significant rate of flow and reduces the likelihood of a blockage occurring in the hose.
The kelly hose must also be able to withstand large amounts of pressure. This applies primarily to the pressure of the fluid flowing through the hose. For this reason, it is often made of highly durable material and is generally reinforced with steel.
In a derrick or drilling rig, the kelly hose connects the standpipe, which is the rigid metal shaft that delivers the mining fluid, to the swivel, which is the piece that supports the weight of and controls the rotation of the drill string. Its purpose is to provide a flexible drilling fluid conduit, as a rigid conduit would be unable to move with the swivel and would therefore disallow movement of the drill string and, subsequently, the bit.
The drilling fluid, sometimes called drilling mud, carried by a kelly hose is critical to operations in several ways. It keeps the bit cool, which helps reduce friction and failure. It also cleans the bit and carries away drill cuttings so they cannot damage the drill assembly. Some varieties are used for additional purposes, such as preventing corrosion and providing hydrostatic pressure. Drilling fluid is not necessarily fluid, but may, in fact, be a solid, liquid, gas or other combined form.
The kelly hose is so named because of its connection with the kelly, the actual mechanical piece that ejects the drilling fluid over the drill string. It may alternatively be called a mud hose or a rotary hose. Failure can occur, despite the rugged construction of the hose. Such failure can lead to damage to the rig or a failure to operate. Failed kelly hoses must be repaired or replaced before mining operations can safely and effectively resume.
