Chemical A105 blind plate BL flange standard American system
After careful comparison, the chemical industry flange standard American system does not have universality under the pressure level of 5.0 MPa, which is different from the European system and should be noted in application.
Temperature consideration of BL flange of A105 blind plate
Various standards of flange have different withstand voltage at different temperature, so they can not be matched randomly. In ansi-150, if the pressure is equivalent to 4.448 n / in 2 = 6.895 kPa (LBF = 0.4536 KGF), it is 667. 2 N / in 2 = 1.034 MPa (150 LBF), but different standards have different pressure resistance at different temperatures. Applicable to different standards of flange, such as mercury, JIS, American National Standards Institute, German National Standards Institute, etc. We not only need to use pressure to correspond, but also consider the temperature class. Even if the same material has different pressure resistance at different temperatures, please refer to resources for details.
