Rotary Vibrator / Drilling Hose

A Rotary Vibrator / Drilling/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.

What is a Rotary Hose

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.

Rotary Hose Are large I.D high pressure flexible rubber steel lines used to connect the swivel to the standpipe.

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.

Rotary Vibrator Drilling/Mud/Pumper/Kelly Hose Specification

Rotary Drilling Hose

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.

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.

Rotary Vibrator / Drilling/Pumper Hose Introduction

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.
The Kelly hose has a diameter of 3-5 inches (inside diameter).

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.

General construction of a High Pressure Drilling Hose

1、Stainless steel interlock stripwound tube
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.

2、Polymer lining
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.

3、Textile plies
To distribute the forces of internal pressure.

The Remaining Part

4、Stiffening spiral (not shown in the picture)
To protect the hose against collapse under axial pulling force and/or as a result of external pressure. Prevents kinking even in sharp bends.

5、Elastomeric cushion plies
To ensure adhesive bonding between different plies.

6、High strength steel cable reinforcements
These are the most important load-bearing elements, they determine internal pressure resistance. The cables are either zinc or brass coated to provide exceptional corrosion resistance.
