15CrMog alloy steel pipe
15CrMoG alloy steel pipe, alloy steel pipe is a type of seamless steel pipe, its performance is much higher than ordinary seamless steel pipe, because this kind of steel pipe contains more Cr, its high temperature, low temperature, corrosion resistance properties are other The seam steel pipe is not comparable, so the alloy pipe is widely used in petroleum, chemical, power, boiler and other industries.
The principle of purifying hydrogen of 15CrMoG alloy steel pipe is that when the hydrogen to be purified is passed into one side of the 15CrMoG alloy steel pipe at 300-500 ° C, hydrogen is adsorbed on the wall of the 15CrMoG alloy steel pipe. Because the 4d electron layer of palladium lacks two An electron, which can form an unstable chemical bond with hydrogen (this reaction of palladium and hydrogen is reversible). Under the action of palladium, hydrogen is ionized into protons with a radius of 1.5 × 1015m and the lattice constant of palladium is 3.88 × 10-10m (at 20 ° C), so it can pass through 15CrMoG alloy steel pipe, under the action of palladium, protons and electrons combine again to form hydrogen molecules, and escape from the other side of 15CrMoG alloy steel pipe. On the surface of 15CrMoG alloy steel pipe, undissociated gas is impermeable, so 15CrMoG alloy steel pipe can be used to obtain high purity hydrogen.

| Brief introduction: more Under the influence of steel prices, the rise in steel prices only lasted for a short period of two or three days, and steel prices returned to the downward trend. On the whole, the overall situation of the domestic steel market is still not optimistic, and the "Golden Nine" peak season is expected to be basically unsuccessful. So can traders still have expectations for the upcoming Silver Ten? The following author mainly analyzes the factors that affect the trend of steel prices. The current problem of overcapacity in China is not a normal state in the market economy, but a result of interventions in the planned economy. For example, some industries with outstanding overcapacity were once encouraged industries. In other words, the current serious overcapacity in some domestic industries may be ... [ detailed ] |
