rotary kelly hose manufacturer

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.

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.

ISO 9001:2000 certified custom manufacturer of abrasion, oil & weather resistant reinforced hose with tubes, covers & fittings for rotary drilling & exploration work. Hose are available in various models with specifications including 2 1/2 in. to 5 in. ID, 3.06 in. to 8.90 in. OD, 5 ft. to 100 ft. length, 2500 psi to 7500 psi rated working pressure, 48 in. to 72 in. minimum bend radius, 3 in. to 6 in. API thread, 2 in. to 3 in. NPT thread, minus 40 degrees F to plus 200 degrees F operating temperature & 3.9 lbs. to 43.6 lbs. weight/ft.

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.

API 7K Rotary Drilling hoses also called oilfield drilling hoses, vibrator hoses, mud hoses, cementing hoses, kelly hoses, de-coking hoses, for the steady high pressure oilfield service. PME Grade D and Grade E rotary hose are designed and produced for mud delivery and cement service on the drilling rigs, by pumping mud at extra high pressure in oilfield drilling operation and exploration.

PME Rubber High Pressure Rotary Drilling Hoses, API 7K Certification, Grade A, Grade B, Grade C, Grade D, Grade E, Grade F.The rotary connection between mud pump and standpipe is called mud hose or kelly hose.

Drilling rotary and vibrator hoses (High Pressure Drilling Hoses) are designed as API 7K Spec as the flexible connection between the standpipe and swivel for pumping mud at a very high pressure in oil drilling and exploration. This hose features high strength spiral steel wire reinforcement which provides a very flexible connection capable of withstanding high pumping pressures at API working pressures, also called mud hose, cement hose, kelly hose or shock-resistant hose.

Our high pressure drilling hoses are often equipped with API end fittings. Connection type covers LP, NPT, TBG and BSPT thread, welding or integral forged union or flange.

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.

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.

The high pressure hoses are a bonded construction comprising steel and elastomeric materials. The principal characteristic of bonded construction is the build-up of individual layers in the flexible hose wall which are then combined into one unit through vulcanisation. Hose assemblies are manufactured as a single bonded unit to specified lengths where the couplings are a chemically bonded integral part of the hose.

Protects the polymer lining from mechanical damage, prevents blistering in case of high pressure gas service and decompression with vacuum service, supports the wall of the flexible hose. This layer is optional and present only for rough bore hoses, such as for flexible choke & kill lines with TauroFlon™ liner.

Fluid barrier of the flexible line. Protects the hose construction from corrosive and abrasive effects of the conveyed medium. The thickness of lining depends on the internal pressure, the inside diameter and the conveyed medium. The lining material is selected to withstand chemical and heat effects of drilling mud, well effluents, cement slurry, hydraulic fluid or whatever substance is conveyed through the hose.

Drilling hose(rotary hose)made according to API 7K spec, applies for flexible hose connection between the top of oil drilling stand pipe and vertical moved swivel joint in well drilling, well cementing, work-over and down-hole servicing operation. drilling hose is also used to adjust the installation mistake between drilling pipe line and stand pipe to avoid shake, sometimes to transfer high pressure oil and water base mud with the lowest aniline point of 60°C from the swivel pipe in high pressure, and down-hole operation high medium such as water, oil etc, drilling rotary hose can be used for prefect work too.
