Pipe Joint Breakage or Pump Casing Cracked

If you your pipe welded joint broke often or pump casing cracked ,it is likely
due to misalignment between pipe and pump casing
The pipe could be pulling to one side ,and is creating a lot of pressure on the pipework
and casing

Remove the bolts and nuts to check if the pipe flange stays parallel to the pump casing flange
Check both pump and pipe centre line , realign

This also cause vibration to pumpsets


Very often contractor weld the pipe first before alignning to the pumpset
and later will try pulling the pipe to meet the pipe pump inlet/outlet
This is very common and happening all the time here

Plant people will always blame the pumpset supplier or coupling not properly aligned
