| index- alloy pipe |
| alloy pipe is
a kind of seamless steel tubes, the performance in general than the
seamless steel tubes is much higher, because such a pipe inside of Cr
more, the high temperature, low temperature-resistant,
corrosion-resistant performance is no other than the seamless steel
tubes On, so alloy pipe in the oil, chemicals, power, boilers, and so
the use of a comprehensive range of industries. Palladium alloy pipe used for the separation of hydrogen and impurities. Palladium hydrogen purification of the principle that, in 300-500 ℃, the question of hydrogen-purification into the side of the palladium, hydrogen absorption was on the wall in palladium, palladium 4 d due to the lack of two electronic electron shell, And hydrogen to generate instability in the chemical bonds (palladium and hydrogen reaction is reversible), in the role of palladium, by ionizing hydrogen proton to its radius of 1.5 × 1015m, while palladium lattice constant of 3.88 × 10 -- 10m (20 ℃), it can be of palladium, palladium and the role of the proton and electron combine and re-formation of molecular hydrogen, from the Palladium on the other side of the escape. Palladium in the surface, not dissociation of gas is not through, it can make use of palladium high Chunqing. Although palladium on the hydrogen through a unique performance, but the mechanical properties of pure palladium poor, high-temperature oxidation at the easy, low-temperature recrystallization and easy to deformation of palladium and brittle, it can not be used for pure palladium through the membrane. Add in the amount of palladium in the IB and Ⅷ ethnic group elements, made of palladium alloys, can improve the mechanical properties of palladium. ABS alloy pipe and plastic for cold fusion is one of them, widely used in building water supply and central air-conditioning, especially in the construction of water legislation and the use of central air-conditioning in the application of. PC / ABS alloy can also produce automotive exterior parts, such as motor vehicles Wheel covers, mirror housing, such as tail Dengzhao. PC / ABS has a good molding, Machinable large car parts, such as automobile fenders.
