DIN17175 SA 192 Boiler Tubes ， 15CrMo 15CrMoG Seamless Black Pipe High Pressure

DIN17175 15CrMo/15CrMoG Seamless Tubes for High-Pressure Boiler description

For high-pressure boiler (working pressure 9.8MPa or more generally, the working temperature between 450℃-650℃) of heating surface tubes, header, economizer, superheater, reheater and so on.

Application For high, middle, low-pressure boiler and pressure purpose 15CrMoG alloy tube of the principles of the purified hydrogen at 300-500 ℃, the hydrogen to be purified is passed through one side of the 15CrMoG alloy tube, the hydrogen is adsorbed on 15CrMoG alloy wall, palladium 4d electron shell lacks two electronics, it can with the hydrogen generating unstable chemical bonds (palladium and hydrogen, this reaction are reversible), palladium, hydrogen is ionized proton whose radius is 1.5 × 1015m, while the lattice constant of palladium 3.88x 10-10M (20 ° C time), it can be through 15CrMoG alloy tube role of palladium proton combined with electronic and re-formation of the hydrogen molecules to escape from the other side of the 15CrMoG alloy tube.

In the 15CrMoG the surface of the alloy tube, not dissociated gas impermeable, can therefore be used 15CrMoG alloy tube to obtain high purity hydrogen.

15CrMoG seamless tubes heat treatment: Normalizing and tempering
