Description
Technical field
The present invention relates to a kind of high-strength magnesium Al-alloy pipe.
Background technique
Tubing is exactly the material for making pipe fitting.The different tubing of different pipe fittings, the quality of tubing directly determines the quality of pipe fitting.These type of tubing multiplex such as construction engineering, power plant, chemical plant, there is operative norm GB/T5310, for high-pressure autoclave: there is operative norm GB/T8163, seamless steel tubes for liquid service: have operative norm GB3087, low pressure boiler seamless steel pipe: have operative norm GB/T9948, seamless steel tube for petroleum cracking: have operative norm GB/T14976, fluid conveying stainless-steel seamless pipe, common material has alloy (15CrMo, 12Cr1MoV) carbon steel (10#, 20#, 45#) stainless steel (304,316).
Can see that these the 5 kinds plastic tubes that can be applied to indoor confession hot and cold water all respectively have its merits and demerits by above contrast, the unique unique advantage of aluminium-plastic composite pipe is the infiltration that can intercept gas, this is useful when being applied to the water heating system of closed circulation (heating system as ground paving hot-water line), because the oxide etch that can prevent the infiltration of oxygen from avoiding in system.Other plastic tubes also can make up the shortcoming of its blocking oxygen difference with several method, so can be applied to the water heating system of closed circulation equally.Except above-mentioned 5 kinds of plastic tubes, outer line plastic-steel tube and pipe fitting and plastic-coated steel and pipe fitting, mould multiple copper pipe, plastic lining aluminium pipe etc. also can be applied to the indoor field for hot and cold water.These linings are moulded or the metal tube of plastic-coated also respectively has its own unique merits and demerits.Such as lining is moulded or plastic-coated steel take Coating Steel Pipe as matrix, its mechanical property reliable the most easily by users to trust.So, at present domestic and international in the field of indoor for hot and cold water above-mentioned various tubing be in fact all used, and all constantly to improve and developing.Aluminium-plastic composite pipe develops very fast at home, can expand market share accordingly from now on, but can not infer that aluminium-plastic composite pipe will become the main flow of indoor water pipe accordingly.Various tubing contention can be predicted and divide the situation accounting for indoor water pipe market by long-term existence.In the field of indoor for cool and hot water pipe, the domestic manufacturing enterprise that all has of above-mentioned several tubing sets up production line, and goes into operation.

A kind of high-strength magnesium Al-alloy pipe of the present invention, have very strong high strength, mechanical property is good, the advantage that cost of production is low.
Embodiment
Below preferred embodiment of the present invention is described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.
Wherein, described high-strength magnesium Al-alloy pipe comprises the magnalium layer of the superiors, polymer matrix composites layer and the undermost refractory alloy layer in mesosphere combine, described polymer matrix composites layer comprises silicon carbide, boron, aluminium oxide and carbon fiber, described magnalium layer accounts for the 21%-24% of the overall component of high-strength magnesium Al-alloy pipe, described polymer matrix composites layer accounts for the 31%-34% of the overall component of high-strength magnesium Al-alloy pipe, described refractory alloy layer accounts for the 40%-50% of the overall component of high-strength magnesium Al-alloy pipe, described refractory alloy layer is cobalt base superalloy, described magnalium layer accounts for 23% of the overall component of high-strength magnesium Al-alloy pipe, described polymer matrix composites layer accounts for 32% of the overall component of high-strength magnesium Al-alloy pipe, described refractory alloy layer accounts for 45% of the overall component of high-strength magnesium Al-alloy pipe.
Further illustrate, refractory alloy is divided three classes material: 760 DEG C of high temperature materials, 1200 DEG C of high temperature materials and 1500 DEG C of high temperature materials, tensile strength 800MPa.Refer in other words more than 760--1500 DEG C and the high temperature metallic material of long-term work under certain stress condition, there is excellent hot strength, good anti-oxidant and hot corrosion resistance, the combination properties such as good fatigue behaviour, fracture toughness, have become the irreplaceable critical material of military-civil gas turbine engine hot-end component.760 DEG C of high temperature materials mainly can be divided into iron-base superalloy, nickel base superalloy and cobalt base superalloy by matrix element.Wrought superalloy, cast superalloy and powder metallurgy high-temperature alloy can be divided into by preparation process.Solution strengthening type, precipitation strength type, oxide dispersion intensifying type and fibre strengthening type etc. are had by schedule of reinforcement.Refractory alloy mainly for the manufacture of turbine blade, guide vane, the turbine disk, the high-temperature component such as high-pressure compressor dish and firing chamber of aviation, naval vessels and industrial gas turbine, also for the manufacture of the conversion equal energy source conversion equipment of aerospace craft, rocket motor, nuclear reactor, petrochemical equipment and coal.
Further illustrate, polymer matrix composites can only use within the scope of the different temperatures below 350 DEG C usually again.Developmental research was applicable to 350 DEG C ~ 1200 DEG C various metal-base composites used rapidly in the last few years.Metal-base composites take metal or alloy as matrix and various reinforcing material compound and obtained composite material.Reinforcing material can be the silicon carbide of threadiness, granular and crystal whisker-shaped, boron, aluminium oxide and carbon fiber.Metallic matrix, except metallic aluminium, magnesium, also develop non-ferrous metal titanium, copper, zinc, lead, beryllium superalloy and intermetallic compounds, and ferrous metal is as metallic matrix.Metal-base composites is except having except high strength, high-modulus equally with polymer matrix composites, and it can be high temperature resistant, does not fire simultaneously, nonhygroscopic, heat-conductivity conducting good, radioresistance.Be compelling Aero-Space high temperature material, can be used as the surfacing of aircraft turbine engine and rocket motor hot-zone and supersonic aircraft.Current development and perfect metal-base composites with fastest developing speed with silicon-carbide particle aluminum alloy.The proportion of this metal-base composites only has 1/3 of steel, is 2/3 of titanium alloy, close with aluminum alloy.Its strength ratio middle-carbon steel is good, close and slightly higher than aluminum alloy with titanium alloy.Its wear resistance is also good than titanium alloy, aluminum alloy.Small lot is applied to automotive industry and mechanical industry at present.What in 5 ~ 15 years, have commercial application prospect is piston of automobile, brake parts, connecting rod, robot components, machine element, sports equipment etc.The invention provides a kind of high-strength magnesium Al-alloy pipe, have very strong high strength, mechanical property is good, the advantage that cost of production is low.
