Overview of Multi functional Crack Propagation Rate Testing Machine Equipment:

FCCMulti functional crack propagation rate(CGR)The testing machine is used for corrosion fatigue loading and crack propagation length measurement of materials in corrosive environments. Crack propagation measurement adoptsDCPDLaw can be applied in corrosive media environments.

Continuous corrosive environments include: high temperature, high pressure, purified water (temperature)0-650℃, pressure0-35Mpa)Water environments containing trace amounts of alkalinity, acidity, and salts can also be used for higher concentrationsNaOHTheNa2CrO4TheN2O4TheHNO3TheNH3OHTheH2STheCOTheCH4IncludingCl-The corrosive environment of solutions, methanol, phosphate hydraulic oil, acetic acid and other media requires consideration of the service life of the high-pressure reactor system when the concentration of some media reaches a certain level.

The required material for the experimental kettle is determined based on the temperature and pressure of the medium and its environment. The metal corrosion high-pressure reactor and its associated hydrochemical control system achieve reliable control of temperature, pressure, hydrochemical control, and water circulation.pHTheDOThe conductivity is controllable across the entire range.
