Fluorine lined check valve enterprise explains how to install flange connection (Part 2)

previously check valve The business people talked to us about several key points on how to install flange connections, and now we will continue to explain the unfinished points. When tightening flanges, it is important to avoid uneven force and follow the instructions to tighten them in a symmetrical and intersecting direction in sequence. After installation, it is necessary to ensure that all components have been evenly fastened. It should be noted that the material of the components must be guaranteed and comply with the product specifications. And to avoid unnecessary looseness caused by unexpected situations such as vibration, attention should also be paid to using washers when tightening, and anti adhesive agents should be applied to the threads to avoid adhesion in high temperature environments.
Since we mentioned the high temperature environment, we cannot forget it here. High temperature used in environments above 150 degrees Celsius PTFE lined valve After the temperature rises, it is necessary to tighten a series of related components again. When tightening bolts at atmospheric temperature, it is important to use torque that takes into account the shrinkage phenomenon of related components in low-temperature environments.
