Alloy tube (Alloy pipe) is a seamless steel pipe, alloy pipe into the structure and high pressure heat-resistant alloy seamless tubes. The main different from alloy tube production standards and industry annealed alloy tube quenched change its mechanical properties. Achieve the desired processing conditions. Its performance is higher than the average value of the use of seamless steel changeable, the chemical composition of the alloy tube containing Cr more, high temperature, low temperature resistance, corrosion resistance. Carbon seamless alloy composition does not contain little or alloy composition, alloy pipe in the oil, aerospace, chemical, electric power, boiler, military and other industries use more extensive reasons because of mechanical properties of the alloy tube varied good adjustments. Alloy tube alloy tube material roughly: 10 #, 20 #, 35 #, 45 # ,16-50Mn, 27SiMn, 40Cr ,12-42CrMo 16Mn 12Cr1MoV T91 27SiMn 30CrMo 15CrMo 20G Cr9Mo 10CrMo910 15Mo3 15CrMoV 35CrMoV 45CrMo alloy tube Category: palladium alloy tube used for the separation of hydrogen and impurities. Palladium principle is hydrogen purification tube at 300-500 ℃, the hydrogen to be purified is passed through the tube side of palladium, the palladium is adsorbed hydrogen wall due to the lack of two shells palladium 4d electrons, it unstable and can generate a hydrogen bond (such palladium and hydrogen reaction is reversible), the role of palladium, hydrogen is ionized proton radius of 1.5 × 1015m, and the lattice constant of palladium is 3.88 × 10 - 10m (20 ℃ pm), it can, through a combination of protons and palladium tube under the action of palladium and electronics and re-form hydrogen molecules escape from the other side of the palladium tube. Palladium tube surface, dissociation is not gas impermeable, it can be used to obtain high purity palladium tube. Although palladium to hydrogen through the unique properties of pure palladium alloy tube but poor mechanical properties, easily oxidized at high temperatures, the recrystallization temperature is low, easy deformation and palladium tube embrittlement, it can not be through the membrane with pure palladium. Add the right amount of palladium and Ⅷ IB group elements, made of palladium alloy, palladium can improve the mechanical properties of 11 automobile axle casing seamless pipe (GB3088-82) is manufactured automobile axle casing and the drive axle shell axis effective high-quality carbon structural steel and alloy steel hot-rolled seamless steel palladium alloys, silver accounting for 20-30%, other ingredients (such as gold, etc.) content <5%. Palladium alloy of the present application, approximately 20-30% of silver, other ingredients (such as gold, etc.) content of <5%. Rate and temperature of the hydrogen-permeable palladium alloy, the thickness and feel both sides of the membrane material and the purity of the hydrogen pressure difference (P) related. Elevated temperature, increasing the thickness of the P and reduced membrane permeability hydrogen rate will increase. But the temperature rise will decrease the tensile strength of the permeable membrane. Therefore, temperature control is typically a palladium tube about 450 ℃. Some impurities can lead to palladium poisoning, so breathable performance deterioration and even make the film destroyed. Palladium can cause poisoning substances are: mercury, arsenic, halides, oil vapor, sulfur-containing substances, and dust and ammonia. Can be made of a tubular palladium alloy (Pd called tube) or membrane (known as a palladium film). ABS alloy pipe and special cold-melt glue is one widely used in building water supply and central air conditioning especially in building water supply riser pipe and central air-conditioning applications with .PC / ABS alloys can also be produced automotive exterior parts, such as car wheel , mirror housings, tail lamp and so on. PC / ABS has good formability, machinability large automotive parts such as automobile fenders. Alloy pipe steel products as an important part of its manufacturing process and the use of different shape and is divided into seamless steel tube (round billet) and welded steel (sheet, strip) two categories. When hydrogen purification palladium tube at 300-500 ℃ principle is the hydrogen to be purified through the tube into the hydrogen side of the palladium is adsorbed on the wall due to the palladium Pd 4d lack of two electron shells can not generate hydrogen stable chemical bond (this reaction of palladium and hydrogen is reversible) in the role of classification palladium alloy tube (1) seamless steel pipe manufacturing process because of the different, is divided into hot-rolled (extrusion) seamless and cold drawn (rolled) Seamless two. Cold drawn (rolled) pipe is divided into circular pipe and shaped pipe. a. Process Overview of hot-rolled (extruded seamless pipe): perforated tube round heated three-roll rolling, rolling or extrusion detached sizing (or reducing) the cooling pipe billet straightening hydrostatic test (or testing) mark storage. Cold drawn (rolled) seamless steel pipe: round perforated tube starts heating annealing and pickling oiled (copper) multi-pass drawing (cold) heat treatment straightening pipe billet hydraulic test (testing) marker storage. b.
