Chinese factory of coal mine high pressure rubber hose for mine

  Chinese factory of coal mine high pressure rubber hose for mine   In rotary drilling, geology and oil needs large capacity by high pressure mud fluid conveying to the drill bit, using rotary drilling hose and hose assemblies used as flexible connectors in the slurry transportation pipeline. Rotary drilling hose at the top of the riser and run up and down between the rotation of the section.Marine mud hose in the barge and ocean drilling platform between the high pressure mud conveying, often more than 13.5 m length. Short damping hose (9 m or less), used in drilling pump and frame between the vertical pipe manifold, in order to apply different axial and vibration isolation.   Drilling hose structure By the inner rubber protection layer, middle layer, innerrubber protectionlayer, middle, wire spiral layer and external rubber cover. Hose lining layer should be made up of oil resistant, water resistant rubber. Hose enhanced layer should be made of fabric and wire (rope) materials. Hose outer cladding should by oil resistance, abrasion resistance and weather resistance of rubber aging, the surface should have a colored band along the length direction, so that the use of hose and installation.   Parameters

We have advanced standards for design, mainly produce stainless steel metal hoses, metal bellows, nets, metal&non-metallic compensator polyurethane, high/low pressure hose, hose sheathed insulation, all kind of connectors and other products. Which are widely used in electric power, dock, construction, steel, mining, petroleum, chemical, cement, transportation and other industries of various pipes and equipment. All the products have passed the ISO9001 international quality system certification.   Honors 1) It has obtained ISO9001-2000 International Quality Certificated. 2) All of the products are determined as " The Best Products of Chinese Technology" by China Technological Enterprise Council. 3)Our company has the right of "Products Import & Export". 4) They are also insured the product quality liability insurance by PICC.   Certificates     Using Instruction: A. When choosing hose, please pay attention to the folloings: Working environment: working temperature, weather, and the connection with other materials. Conveyable Matter: Liquid, gasses, solid, mixture of above matters. Convey ways: delivery matter under the pressure, delivery and suction under vacuum. Working condition: the pressure and temperature for convying matter, use frquency, impulse and movement. Installation: Bending,vibration of the system, the risk of damaged caused by hitting and friction, application of the right connecting mode.   B. There is limited life for hose assemble;please pay attention that the followings woud reduce the hose useful ife: a. Making the bend radius smaller than the min bend radius. b. Twisting, stretching, weld line, squeeze or corrode the hose. c. To be used exceeded max temperature or lower the min temperature. d. To be used exceeded the impulse pressure of the max working pressure(the impulse pressure means the rapid rise of pressure). e. The quality of fitting is not up to the standard and assembling is not well.   C. Requirements for using hose: a. The pressure(including the impulse pressure)filled in the hose must not be exceeded the max working pressure. b. Hose can not be used under the temperature not stipulated or suggested including the conveable matter. c. Hose can not be used under the bend radius that is smaller than the min bend radius stipulated or suggested, or it will block the matter passing, and reduce the hose useful life. The hose should be prevent from twisting or warping around the connection part, because the bending for this part will damage the reinforcement, as a result, the hose will be damaged quickly. d. The hose can not be used when it is twisted. e. The edge of hose fitting should be smooth; the size of mandril, sleeve or other accessory must be in confirmed. Less or more control of assembling power will also damage the assembly,. f. There is a limited life for hose, please check and change it regularly.
