Steel at high temperatures by external force, will gradually continue to produce plastic deformation. The temperature rises or the stress increases and the creep speed increases. For high-temperature long-term operation of the boiler, steam pipe steel used must be good creep resistance, to avoid creep deformation caused by structural rupture or cause an explosion and other accidents.
Under the action of high temperature, the cementite in the carbon steel will migrate and aggregate due to the energy acquisition, the formation of coarse cementite and mixed in the ferrite, the cement body will gradually change from the sheet into a spherical, For the ball. Because the graphite strength is very low to the existence of sheet, the material strength greatly reduced, increased brittleness, known as graphitization.
Stainless steel duct production line
costs are not high, easy to install. Installed in many locations will not be limited, widely used. Installation and disassembly can be completed in the shortest possible time, and even if the damage is also easy to repair. Does not belong to the filter structure, there is no layout of the oil box. More convenient cleaning. Ventilation effect is good, strong pollution, there will be no leakage of the basic situation.
