Abstract
The present invention is a kind of refractory heat-insulating hose, mainly is made of rubber, fireproof paint, knitmesh and sheath or rubber pipe, steel wire winding layer, rubber layer, refractory paint, thermal-protective coating, knitmesh and sheath etc.Characteristics such as have refractory heat-insulating, bending radius is little, and is shock-resistant, easy to use, inexpensive, the naked light refractory temperature reaches more than 750 ℃, and 30 minutes, the withstand voltage 42MPa that reaches.Be mainly used in the hydraulic transmission equipment of high temperature, inflammable, hyperbaric environment, as oil exploration blowout control equipment hydraulic control pipeline, the steel-making of metallurgy industry, blast furnace, open hearth etc. transmit occasions such as medium near naked light high temperature place hydraulic equipment.
Description
The invention belongs to liquid conveying hose, be mainly used in the conveying of liquid under the high temperature condition in the industries such as oil, chemical industry and metallurgy.
The oil pressure flexible pipe that in the past used on the steel making furnace, heat resistance is poor, and working life is short, and the external steel hard tube line that uses in the oil well blowout control equipment has easy leakage, distortion, installation inconvenience, meets deficiencies such as naked light quick heating and refractory nature difference.The flexible pipe (outsourcing bellows) of drilling well that U.S. COFLEXIP produces and service purposes, all undesirable at aspects such as fire resistance period, crooked pliability, cost and working lifes.
The purpose of this invention is to provide the refractory heat-insulating hose series product, use in equipment such as metallurgy, can not only satisfy usage requirement, resistance to high temperature is good, and bent toughness is good, long service life; In equipment such as oil blowout prevention, use, the refractory temperature height, fire resistance period is long, and crooked pliability is good, and is withstand voltage, and cost is low, and long service life.
The present invention is achieved in that for the general refractory heat-insulating hose that uses in the industries such as chemical metallurgy its structure is that from inside to outside, first layer is a rubber layer, as the ordinary rubber pipe, itself is with the rubber pipe of steel wire or nylon thread winding etc.; The second layer is a fireproof paint, J60-90 that produces as Tianjin or ER-863 etc.; The 3rd layer for knitmesh, promptly directly is made into the iron net at skin, or twines iron net, iron platinum etc., with fastening and make it have certain crooked pliability; The 4th layer is sheath, available heat fusibleness rubber (PVC modification), bellows, and the fire resistant coatings that vulcanized rubber or Tianjin produce etc. have protective actions such as shock resistance, the most handy fire resistant coating.For improving its refractory nature, between fireproof paint layer and knitmesh, can wrap with the flame-retardant textile layer, as glass fiber cloth or push away nylon cloth etc.Also can set up the fireproof paint layer again between flame-retardant textile layer and knitmesh, one deck or which floor flame-retardant textile layer and fireproof paint layer add.Between knitmesh and sheath, preferably has the poly-vinyl alcohol solution adhesive coatings.
For refractory heat-insulating of using in the equipment such as oil well blowout prevention and flexible pipe with certain resistance to pressure, its structure is, from inside to outside, first layer is a rubber pipe, close or rubber or common oil resistant rubber pipe etc. as the fourth eyeball, the second layer is that steel wire twines skeleton, so that it is withstand voltage, and certain bent toughness arranged, around one deck or which floor; The 3rd layer is again rubber layer; The 4th layer is the fireproof paint layer; Layer 5 is a thermal-protective coating, and useable glass fiber, glass wool, rock wool, alumina silicate or polyvinyl alcohol add an amount of rock wool etc.; The 6th layer is knitmesh, and the 7th layer is sheath.For improving its usability, be preferably in and set up fireproof paint layer and/or fastening fire-retardant winding layer between thermal-protective coating and knitmesh, as twining with flame-retardant textile or with the galvanized wire winding etc.For improving its refractory nature again, be preferably in and set up poly-vinyl alcohol solution coating and/or fireproof paint layer (it is the same not state notion) between knitmesh and the sheath again.
Base of the present invention is managed and is, and is not only heat-resisting but also prevent fires, anti-again certain pressure, and the sheath protection, and wrap very tightly, when using, bending has good performance equally.
First series product of the present invention have good Fire insulation, and crooked pliability and shock-resistant usability are fire-resistant generally more than 600 ℃, and the time if lose naked light, can use under 300 ℃ of states more than 30 minutes for a long time.Can satisfy the usage requirement under the high temperature operating conditions such as metallurgy, chemical industry.
The refractoriness of second series product of the present invention can reach 750 ℃, and more than time 20-30 minute, crooked pliability is good, and general bending radius is about 0.3m.Can satisfy the usage requirement of oil well blowout control equipment well, in case when the blowout fire takes place, because of it can resist combustion half an hour in raging fire, can provide the enough time to start hydraulic blow out preventer, close well head, the cut-out burning things which may cause a fire disaster makes fire hazard be reduced to minimum degree.Duo Jia uses in the oil field, and effect is fine.The present invention is successful Application on the oil recovery well at sea also.External relevant expert thinks that product of the present invention is in fire resistance period, crooked pliability, impact resistance, and aspects such as usability all have superiority, and require the corrosion protection aspect especially at sea in the operation, is that the above-mentioned flexible pipe that is applied to drilling well and service purposes is inaccessible.
Below be the test result of national product quality supervision and test test center to refractory heat-insulating high pressure hose of the present invention, check is according to International Power association criterion (IEC331) and American Petroleum Institute's related standards (APL), detect conclusion: 750 ℃ of naked light combustion temperature, after 30 minutes period of combustion, flexible pipe rubber topping sheath burns, and flame is not by refractory layer, and as seen the sebific duct middle part cuts off dissects, the sebific duct internal layer does not fire, and does not have distortion.Oil resistance: in hydraulic oil temperature 40-100 ℃, soak 24H, there is not rotten obscission.Resistance to acids and bases: in 4%HCl and 4%NaOH solution, soak 24H respectively, no change.Anti-artificial seawater: in artificial seawater, soak 24H, no change.Pressure test: 3.15MPa voltage stabilizing 3 minutes, do not have and leak.More than the acid pressure 42MPa.Heat insulation test: when medium is clear water the outside and inside temperature ratio of flexible pipe greater than 4,300-500 ℃ of time of steel plate heating-up temperature, 20 minutes.Minimum bending radius is tested less than 300mm, no change, medium clear.All conform with standard and usage requirement.
