Difference between 15CrMoG alloy pipe and 15CrMoG alloy steel pipe

Difference between 15CrMo alloy pipe and 15CrMoG alloy steel pipe and its characteristics The principle of purifying hydrogen is to use under high temperature environment and withstand a certain pressure. When the hydrogen to be purified is passed into the side of 15CrMoG alloy steel pipe at 300-500°C, Hydrogen is adsorbed on the wall of the 1515CrMoG alloy steel tube. Since the 4d electron layer of palladium lacks two electrons, it can generate an unstable chemical bond with hydrogen (this reaction of palladium and hydrogen is reversible). Under the action of palladium, hydrogen The ionized protons have a radius of 1.5×1015 m, and the lattice constant of palladium is 3.88×10-10 m (at 20° C.), so they can pass through 15CrMoG alloy steel tubes. Under the action of palladium, protons combine with electrons and reform hydrogen. The molecule escapes from the other side of the 15CrMoG alloy steel tube. On the surface of the 15CrMoG alloy steel tube, the undisassociated gas is impervious, so the 15CrMoG alloy steel pipe can be used to obtain high purity hydrogen.

5CrMo steel is a widely used steel in the power industry and has a high thermal performance at 500°C-550°C. When the use temperature is greater than 550°C, its thermal strength performance is significantly reduced. Usually 15CrMo steel is mainly used for high and medium pressure pipelines with steam parameters of 510°C, steam pipes, and heat pipes with a wall temperature of 550°C.
Foreign steels of the same type include the former Soviet Union's 15XM, the American Trademarks T12, P12, the Japanese Trademarks STBA22, STPA22 and the German 13CrMo44.
The normal microstructure of 15CrMo steel is ferrite plus pearlite. During the long-term operation of 15CrMo steel at a working temperature of 500°C to 550°C, pearlite spheroidization and alloying elements between solid solution and carbide occur. With the redistribution and the change of the carbide phase structure, the thermal strength and mechanical properties of 15CrMo steel gradually decreased as the degree of pearlite spheroidization and the degree of depletion of solid solution as the alloy element increased, so that the material gradually deteriorated or even failed. Therefore, the degree of pearlite spheroidization in 15CrMo steel structures has long been widely used as one of the important criteria for determining the reliability of such steels.

In other words, lowering the speed increases the torque. A planetary gearing system has a ring gear with a sun gear at its center and three planetary, or pinion gears, equal distances apart from each other that rotate around the sun gear. The shaft that connects the hydraulic travel motor to the Final Drive gearbox turns the sun gear at a super-high speed. The planetary gears mesh with the sun gear and turn while rolling around the ring gear. They spin at a slower rate than the sun gear, and that speed reduction increases torque.
