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.

Owing to over twenty years market experiences in supplying high-pressure flexible oilfield rubber hoses, Hebei Qianli Rubber Products Co., Ltd. has been an important partner of many famous customers including America, East Asia, Africa and other countries and regions in the world.

Oilfield drilling hoses are vital components for rig drilling systems. Rotary drilling hose, mud hose, cement hose, Kelly hose, vibrator hose are working under high-pressure. Once the hose failure, it will cause catastrophic damage to the equipment, body health and property. Our professional engineers can help you solve any problem in safe storage, handling and other technical problems.

Drilling hoses should work in harsh environments. Therefore, high performance such as abrasion resistance, pressure capacity and life expectancy should be paid much attention to when you select them. If you have any problem with the drill hoses, contact us – bond@hebeiqianli.com.

Our drilling hoses are equipped with API end fittings – flanges, NPT threads and butt-weld unions to meet requirements on the market. Bespoke end fittings are also available.

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 rotarydrilling and pumping equipment against vertical wave action on offshore drill platforms. The Motion Compensator hose is not recommended for phosphate ester fluids.

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.

13 Causes Of Hose Failure 1) Mis-application -Perhaps the greatest cause of failure is using a hose, fitting, or clamp in an application that it is not designed for.

2) Kinking at or near the fittings -Once the barb of the fitting cuts into the tube of the hose, the product being conveyed can escape into the reinforcement and eventually lead to bubbling or blistering of the cover within several feet of the end.

3) Temperature Exposure- As temperature increases pressure ratings decrease. Excessive hot or cold temperatures will lead to discoloration, cracking, or hardness - as well the build up of static electricity if hose wire has not been ground properly.

5) External damage to hose carcass -Kinks, crushed sections, and cover damage which exposes reinforcement will eventually break down the reinforcement and lead to a hose failure.

6) Exceeding the minimum bend radius -Kinking, crushing, or forcing a hose to bend beyond its minimum bend radius (measured from the inside edge of the hose, not the centerline). This is commonly seen on high pressure hoses or vacuum hoses.

7) Defective hose or improperly installed or selected clamp -Failure from a defective hose will typically occur in the first few hours of service, such as pin holes, blow-outs, or tube and cover separation. Improperly installed or selected clamps can result in the coupling ejecting from the end of the hose. Always confirm the manufacturer recommendations based on STAMPED information.

8) Tube or cover not compatible with fluids or environment -Usually results in discoloration, swelling, sponginess, or the breakdown of the hose carcass. For material handling hoses, always rotate to ensure even wear of the hose tube.

9) Old age -Hose is not ‘pipe’, it is a flexible component that will degrade over time. Shelf or service life will range from 1 to 20+ years, depending on its composition, application, and environment. Older hoses become discoloured, stiff, or burst at low pressures.

10) Incorrect hose length -Too short of a length does not allow the hose to expand/contract due to changes in pressure or temperature and causes excessive stress on the fittings or hose reinforcement.

11) Twisting hose during installation or service -Twisting a hose rather than naturally bending the hose will reduce life. It is estimated a 7% twist when installing a hose in a permanent application can reduce hose life by 90%.

12) Poor workmanship -Hose and fittings are made of a unique blend of different materials with complex manufacturing methods - human error, inconsistent machinery, or poor product quality or raw materials can result in defects or variances greater than allowable tolerances. As for failure at the end fitting, ends blowing off assemblies can be a result of sub-standard coupling procedures or due to the “mixing-and-matching” of incompatible hose, couplings, or clamps.

13) Contaminated media being transferred -Foreign particles or residue in the fluid or air can flow through the tube and break it down or wear it out prematurely. Always clean hoses prior to installing in field to ensure there is no cross-contamination.

Heavy machinery fires are often caused by hydraulic hose failures.  Pressurized hydraulic fluid escaping from a failed hose assembly can be atomized into a fine spray that can be ignited by heated engine surfaces such as the engine exhaust or turbocharger.

Hydraulic hoses often fail due to age and wear, requiring regular inspection and replacement of hydraulic hoses to prevent failures. Hoses may also fail if they are misrouted.  Misrouting can lead to the hose being pinched or causing it to chafe against a sharp metal surface.

Hydraulic hoses can also fail due to improper assembly.  Hydraulic hose assemblies are made by cutting a section of hose to length and then crimping metal fittings on each end. Hydraulic hoses differ in material and construction by manufacturer but generally have three layers; an inner leakproof layer that conveys the hydraulic fluid, a reinforcing layer of metal braid, and an elastomeric outer layer that protects the inner layers from wear and environmental exposure.

Hydraulic hoses must be assembled with compatible fittings and strict adherence to the manufacturer’s directions.  The ends of some hydraulic hoses must have the outer layer removed before the fitting is installed, a process called skiving, though not all hoses require skiving.  The fittings must be fully installed on a squarely cut hose prior to crimping them in place.  The correct die and crimping machine specified by the hose manufacturer must be used. The fittings must be measured after crimping to ensure that they were crimped to the manufacturer’s specifications.

Fittings can separate from the hose ends under pressure if they are under or over-crimped, the hose is not fully inserted into the fitting before crimping, an incompatible fitting is used, or the hose is not prepared in accordance with the manufacturer’s directions. Over-crimping also can provide a leak path within the fitting that allows the hydraulic fluid to migrate between the outer and reinforcing layers, leading to bubbles in the hose near the fitting and eventually rupturing the outer layer, exposing the hydraulic fluid to possible ignition sources.  Hoses with visible bubbles should be replaced immediately.

When a fire occurs, hydraulic hoses are often consumed, complicating the evaluation of whether a hose failure led to the fire.  Visual inspection and micrometer measurements can determine whether a suspect hose fitting was properly crimped to the correct diameter. If a hose is partially consumed, the fitting on the undamaged portion of the hose can be sectioned and examined for proper assembly.

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.

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. The drillstring portion of the drilling line and the connection to the rotary hose is thus crucial.

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.

Made of heavy rubber and steel cables the hose is basicly flexible piping that allows the Kelly and the bit and drill string to be raised and lowered while the drilling fluid is pumped through drill string.

lowering the drill string and pumping drilling mud is very important to the drilling process and when these hoses go down or fail in service a entire rig can shut down.

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.
