definition of kelly hose pricelist

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.

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.

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.

The kelly provides a connection between the rotary table, also called the kelly bushing, to the drill string that allows the drill string to turn around its longitudinal axis and move up and down along its length. The hole in the kelly is matched by a hole in the kelly bushing that allows for the passage of drilling fluid into the bore. A kelly is used in fluid or oil assisted bore projects.

99 (opens in new tab)at Bed Bath & Beyond (opens in new tab)Pros+Large dust cup+Comfortable handle+Good pick-upCons-Bulkier to store than a cordless vacuum-Brushroll can"t be switched off-Wand can be cumbersome for overhead cleaning One minute reviewShark is well known for making some of the best vacuum cleaners (opens in new tab) around and we know the brand as one of the frontrunners when it comes to cordless vacuums (opens in new tab)

In the UK it"s known as the Shark Anti Hair Wrap Bagless Cylinder Pet Vacuum CZ250UKT, meanwhile those in Australia should look out for the Shark Bagless Barrel Vacuum CZ250

It"s a great choice for those who don"t like upright or stick style vacuums or for anyone who wants a reliable clean without having to worry about how much battery is left

(opens in new tab)It"s well priced in comparison to cordless vacuums and is also cheaper than Shark"s top-of-the range canister vacuum, which comes in at $479

4kg without the hose or any attachments in place and without a full dust cup, the canister itself is a pretty good weight for most people to carry up and down stairs, the large carry handle and rubberized grip certainly help, too

2 inches/49 x 26 x 26cm (h x w x d) and there are plenty of different configuration options for storage, depending on whether you"ve got a tall or short cupboard space

There"s a powerful self-cleaning brushroll that"s designed to remove debris from deep within carpet fibers, whilst avoiding that annoying clog of hair around the brush

Although it"s not quite so easy to maneuver in this mode, we didn"t feel we had as much control over the direction of vacuuming as when it"s in standard mode

The floorhead is self-supporting so when you click it upright to go and move a stray sock out of the way, it stays put without falling over or having to be placed on the floor, plus the brushroll will automatically pause

(Image credit: Future)General pick up is good on both carpet and hard floor and the beauty of a plug-in vacuum means you don"t feel the need to use one of the lower power levels to conserve battery, you"ll only need to switch to lower power for vacuuming delicate rugs or upholstery

Edge cleaning is good, too, and it was able to collect oats from along our baseboards no matter whether we approached with the front or side of the floorhead

The canister is small enough to balance on stairs and by removing the wand and attaching the floorhead or one of the tools directly to the handle, cleaning stairs is a breeze

(Image credit: Future)The dust cup is easy to remove and during our tests all of the dirt and dust fell straight out into the trash at the push of a button

Having said that, though, the large capacity means you don"t have to do this too often, which is particularly helpful if you"ve got allergies and are sensitive to the usual dust cloud that erupts upon emptying a vacuum

9% of dust and allergens inside the vacuum and the large dust canister means you shouldn"t need to empty it too regularly either, great news for allergy sufferers

Don t buy it if You want the freedom of a cordless vacuum While there are positives to a plug-in vacuum, the negative is that you can"t stray further than 25 ft / 9 meters from a power socket so there"s less freedom, which won"t suit everyone
