Description
Technical field
The utility model relates to a kind of flexible liquid delivery pipe, especially a kind of high pressure fire-retardant heat-insulated spray-proof flexible pipe of carrying the high temperature and high pressure flow body medium.
Background technique
In oil exploration drilling in the used preventer that prevents blowout or will carry the liquid medium of High Temperature High Pressure in the hydraulic control circuit in the steelmaking equipment in the employed pipeline usually, if employing steel pipe, it easily leaks, yielding, meet the naked light quick heating, refractory nature is poor, laying is in the open air got up also very difficult, therefore, has now been replaced by flexible pipe basically.It is metallic hoses that some its internal layers are arranged in the existing flexible pipe, and this is unnecessary at the liquid medium that is used for the no solid impurity of hydraulic control circuit delivery pipe conveying, and its shortcoming is that also its cost is higher and crooked flexibility is relatively poor.It is rubber layer that some its outer walls are arranged in the existing flexible pipe, and such flexible pipe refractory nature is poor, especially has the occasion of meeting naked light danger all inapplicable at oil drilling or field of steel-making etc.
Also having outer in the prior art is the high pressure fire prevention thermal insulation flexible pipe of rubber layer for the oven wire mesh blanket inwall, in order to make the pipe high temperature resistant heat insulation, refractory masses is set between internal and external layer, for can be high pressure resistant, steel wire floor is set therebetween, establishes steel wire floor in the outside of innermost rubber layer often, will establish rubber layer again toward contact in the outside of steel wire floor, refractory masses is set outside it, and outermost is established the Stainless Steel Wire braid.Such flexible pipe has three problems, the one, refractory masses sees through the Stainless Steel Wire braid and partly exposes, the general refractory material that uses is an aluminum silicate fiber, also be called loose wool, its fiber strength deficiency, wind erosion-resistance performance is also poor, therefore, especially in the open use the refractory masses rapid wear in the environment; The 2nd, the existing flexible pipe capability of antidetonance is not high; The 3rd, existing flexible pipe will be provided with rubber layer in the middle of refractory masses, refractory masses is compressed, and like this, flexible pipe weight is increased, and cost improves.
Summary of the invention
The purpose of this utility model provides a kind of light weight, softness, can resist naked light, wind erosion-resistance performance is good and explosion-proof, the high pressure fire-retardant heat-insulated spray-proof flexible pipe of long service life.
For achieving the above object, the utility model is taked following design proposal:
The tube wall of this high pressure fire-retardant heat-insulated spray-proof flexible pipe is from the inside to the outside successively: first layer is a rubber layer; The second layer is a steel wire floor, and described steel wire can be one deck to six layer steel wire, one to three layer steel wire in this way, and steel wire is a Weaving type, four to six layers of steel wire in this way, then steel wire is a winding type, is provided with rubber layer between adjacent two-layer steel wire; The 3rd layer is fire-resistant explosion-proof material layers, in this layer, comprise the several layers refractory masses, it constitutes for the aluminum silicate fiber loose wool, explosion-proof layer of fibers is distributing between adjacent aluminum silicate fiber loose wool layer, this explosion-proof layer of fibers is the 0.1-10 micron by diameter, and length constitutes at the explosion-proof fiber (being also referred to as explosion-proof defend and split fibre) of 1-10 millimeters long, and they are the state of mutual overlap joint, bridging in described aluminum silicate fiber loose wool; The 4th layer is the fire-resistant heat insulating material layer, is the aluminum silicate fiber layer, and layer 5 is the high-temperature coatings layer, layer 6 stainless steel braid.
This blowout prevention flexible pipe has increased a fire-resistant explosion-proof layer on the basis of existing blowout prevention flexible pipe, establish refractory insulating layer outside this layer.In use, when body was heated, these explosion-proof fibers can make this fire-resistant explosion-proof layer intensive, and more and more tighter, thereby had prevented the explosion of body when being subjected to high pressure effectively.
Further, rubber layer no longer is set between fire-resistant explosion-proof layer and refractory insulating layer fire-resistant explosion-proof layer is carried out the integral body constraint,, press tight more more because this fire-resistant explosion-proof layer in use can be more and more intensive as mentioned above.Like this, under the situation that has increased fire-resistant explosion-proof layer, there is no need, add one deck rubber restraint layer as prior art.In actual use, in order to prevent the loose displacement of fire-resistant explosion-proof layer before using, can be provided with several steel wires that lash every a segment distance and get final product in the longitudinal direction.Therefore, said structure can make this flexible pipe in light weight, and cost also decreases.
In addition; the outside of the described refractory insulating layer of this blowout prevention flexible pipe in the stainless steel braid is provided with one deck high-temperature coatings layer, and it has strengthened aluminum silicate fiber intensity and wind erosion-resistance performance, prolongs the working life of aluminum silicate fiber; therefore, can protect the aluminum silicate fiber refractory insulating layer effectively.Described high-temperature coatings layer is generally hard pitch, and the thickness of coating layer is generally 0.02-0.07cm.
The high pressure fire-retardant heat-insulated spray-proof flexible pipe that model utility provides, owing to adopted fire-resistant explosion-proof material layers, between fire-resistant explosion-proof material layers and refractory insulating layer, do not establish rubber layer, and in outermost stainless steel braid, be provided with the high-temperature coatings layer, therefore, the high pressure fire-retardant heat-insulated spray-proof flexible pipe that the utility model provides has light weight, soft, can resist naked light, the advantage that wind erosion-resistance performance is good and explosion-proof, compare with the thermal insulation blowout prevention flexible pipe that existing thickness is similar, weight is little, bending performance is good, be more suitable in high temperature, the conveying of high-pressure liquid all can use safely under the various rugged environments of indoor and outdoor, and working life is longer.
