Hi Mike.. .
I have read your post about Floor truss designing. If you have to need any help please tell me.

I have a pipeline with a DP of 900 psi that will be Hydrotested to 1125 psi


in this pipeline there are 6 ball valves to drain/ vent the pipeline. Those valves (rating # 600) and accordingly the max operating pressure for those valves are 1480 psi.

can I hydrotest the pipeline with valves in closed position, and without installing blind flanges because it is difficult to remove during the hydrotest?

Hi there can anyone assist with resetting blower oil timer for amada fo4020nt please
