If several pipelines with different pressures converge into one, could there be a phenomenon of mutual pushing?

The phenomenon of mutual blocking: In my understanding, it means that those under high pressure prevent those under lower pressure from moving forward along the process, and it’s even possible for those under high pressure to override those under lower pressure
There can be a phenomenon of mutual interference; pipelines with higher pressure may hinder the flow of fluid in those with lower pressure, and reverse flow may even occur. .
It should depend on the pressure in the main pipe; if the pressure in the main pipe is lower than that in the branch pipes, then the fluid from those branch pipes can flow into the main pipe. However, if the diameter of the main pipe is small and its pressure is higher than that of a certain branch pipe, then the fluid from that branch pipe will definitely flow back
It mainly depends on the pressure at the end where the fluid is going; if the pressure difference is large and the pipe diameter allows sufficient flow, then there is generally no problem. On-site, it is also necessary to consider the specific locations of the joints between each branch and the main pipe, as well as the pressure levels in each case. If a branch is located far away and has low pressure, it will be difficult to integrate it into the main pipe.
