A layer of steel wire, rubber hose, high pressure hose points two layers of steel wire, rubber hose, three layers of steel wire, rubber hose, steel wire hose, four layers and six layer steel wire hose, points according to the requirement, and can be divided into hydraulic equipment with high pressure rubber hose, coal mine high pressure rubber hose, high pressure drilling hose, steel high pressure rubber hose, power plant high pressure rubber hose, oil field high pressure rubber hose, environmental protection equipment high pressure rubber hose, high pressure hose that resistance to high temperature and high pressure hose,Acid and alkali resistance high pressure hose, oil resistance high pressure hose, ocean pressure hose, sandblasting high pressure hose, steam high pressure hose, heat conducting oil high pressure hose, different pressure, different quality, different prices.
In geological and petroleum rotary drilling, it is necessary to transport large capacity fluid mud to the drill bit through high pressure. The rotary drilling hose and the hose assembly are used as flexible connectors in the mud conveying pipeline.
The rotary drilling hose is used between the top of the riser and the rotary joint running up and down.Offshore mud transfer hoses are used to transport mud at high pressure between barges and offshore drilling platforms and are usually longer than 13.5m.
Shorter (9m or less) cushioning hoses are used between the pump and the drilling rig, i.e. the riser manifold, to accommodate different shafts and to isolate vibrations.It is composed of an inner adhesive layer, an inner adhesive protective layer, a middle adhesive layer, a wire winding layer and an outer adhesive layer.The hose lining shall be made of oil and water resistant rubber.The hose reinforcement layer shall be made of woven fabric and wire (rope) material.The outer coating of the hose shall be made of rubber which is resistant to oil, wear and weather aging, and the surface shall have a colored band along its length for installation with the hose.
