Rotary Drilling Hose is the customary name for "rotary drilling and shock absorption rubber hoses", and it is also commonly called "drilling equipment hose" and "water hose".

In geological and petroleum rotary drilling, high-pressure fluid slurry needs to be delivered to the drill bit by high pressure, and rotary drilling hoses and hose assemblies are used as flexible connections in the mud conveying pipeline.

Rotary drilling hose is used between the top of the riser and the rotating joint that runs up and down. The marine mud conveying hose is used for high-pressure mud transportation between the barge and the offshore drilling platform, and the length is usually greater than 13.5m.

The shock-absorbing hose is short (9m or less) and is used between the pump and the rig, that is, the riser manifold, to apply different axiality and isolate vibration.

 

Structure
 

It consists of inner rubber layer, inner rubber protection layer, middle rubber layer, steel wire winding layer and outer rubber layer.

The inner lining of the hose shall be composed of oil and water resistant rubber.

The hose reinforcement shall consist of textile and wire (rope) materials.

The outer coating of the hose shall be composed of oil-resistant, abrasion-resistant and weather-resistant rubber, and the surface shall have a colored band along its length to facilitate installation and use with the hose.

 

Application
 

Wire-wound drilling hose is used in oilfield cementing, workover and petroleum geological exploration, small drilling rigs and hydraulic coal mining, fluid transportation such as mud
