15 CrMoG alloy steel pipe

15 crmog alloy steel pipe is a kind of seamless steel pipe, its performance is much higher than the average seamless steel tubes, because this kind of steel tube containing Cr inside is more, its high temperature resistance, low temperature resistance, corrosion resistance is the performance of the seamless steel tube than the other, so the alloy steel pipe in petroleum, chemical industry, electric power, boiler, etc used more extensive.

15 crmog alloy steel pipe is the principle of hydrogen purification, under the 300-500 , the stay purified hydrogen bubbled into 15 crmog alloy steel tube side, the hydrogen adsorption on 15 crmog alloy steel pipe wall, as a result of the palladium 4 d shell lack of two electrons, it can generate unstable with hydrogen bonds (palladium and the reaction is reversible hydrogen), under the action of palladium, ionized hydrogen protons as the radius of 1.5 x 1015 m, while palladium lattice constant of 3.88 x 10-10 m (20 ), so by 15 crmog alloy steel pipe, under the action of palladium and protons combined with electrons to form hydrogen molecules, escape from the other side of the 15 crmog alloy steel pipe.

In 15 crmog alloy steel pipe surface, not can't be through by the dissociation of gas, so the available 15 crmog alloy steel pipe to obtain high purity hydrogen. Although is unique for hydrogen through palladium performance, but the poor mechanical properties of the pure palladium, oxidable at high temperature, recrystallization temperature is low, easy to make 15 crmog alloy steel pipe deformation and brittle, so can't use pure palladium through the membrane. By adding a palladium IB and g element, made from alloy, palladium can improve mechanical properties of palladium.

Hunan great steel pipe co.,ltd is the good supplier of this kind of steel pipe.
