How to choose correct size of concrete pump pipe flange
When selecting the appropriate flange, choosing the right size is just as important as selecting the correct type. An incorrect size can lead to issues such as the inability to install the pipelines or a failure of the sealing surfaces to mate properly, which can severely impact the efficiency of concrete pumping operations on the job site.
We have compiled a size guide for each flange type below for your reference.
