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 hose for drilling is also used for damping vibrations of rotary plants. In this case, it is made of small length and serves as a compensator.
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.
The drilling hose consists of several successively stacked rubber layers and a metal braid.
- The base is an internal rubber tube, manufactured using special rubber and synthetic mixtures.
- Next layer is a textile braiding.
- The power metal braid is made of high-strength aluminum wire, which is laid on one of the rubber layers by a coiling method.
Rotary Drilling Hose with Multiple Layers of High Tensile Steel Wire Reinforcement
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.
The details of rotary drilling hose:
Structure: it is composed of three parts: tube, reinforcement and cover.
Tube: high quality synthetic rubber, mainly NBR, which is resistant to abrasion, corrosion and oils.
Reinforcement: 2-8 layers of high tensile and high strength spiraled steel wire, making the hose work well in high pressure working conditions.
Cover: high quality synthetic rubber, mainly chloroprene rubber, making the hose resistant to abrasion, corrosion, cut, weather, ozone, aging and sunlight.
Working temperature: -30 °C to +82 °C.
Note: Rotary drilling hose can be divided into five kinds according to the working pressure: grade A, grade B, grade C, grade D and grade E.
Application of Rotary Drilling Hose:
It is mainly used for conveying water-based or oil-based mud and other fluids.
It is often used for oil fields, cement repairing, geological exploration and water conveyance for coal excavation.
