Product Description

 

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.
