Pressure rating of high pressure rubber joint
High-pressure rubber joints are relatively low-pressure rubber joints.
Common pressure grades of low and medium pressure rubber joints are:
DN15-DN3200: PN0.25, PN0.6, PN1.0
DN15-DN1400: PN1.6
high pressure rubber joints pressure grades are:
DN15-DN800: PN25
DN15-DN200: PN40
DN15 -DN800: When the PN64
high-pressure rubber joint works under high pressure, the temperature of the medium should not be too high. As the temperature of the medium increases, the lower the working pressure that the rubber joint can withstand.
In addition, frequent repeated high pressure and normal pressure conversion will quickly damage the rubber joints and easily leak water.
