Skid Base frames

[prmmel]

We have historically manufactured 5-150HP blower base frame packages from carbon steel. We are transitioning to AL. These base frames typically consist of a motor direct drive to a blowerhead on a frame. By changing to AL, we have agreed that we may need to beef up the frames accordingly, but we are concerned with vibration causing issues. There are no shear points on the frame, basically just 4 bolts on the motor and 4 on the blower. They are typcially supported on 3", 4" or 6" channel that is inverted or flat plate. We are looking for advise if anyone knows of reasons not to do this.

Thanks,

Mel

Hi prmmel

Can you not get an analsys done?
What about possible corrosion problems between aluminium and other steel parts like bolts for example.

If oxidation is an issue, we would paint accordingly where needed. Typical equipment indoors will not have an issue. I did not want to drag out in analysis of the metals. We have built about 10-15 units of AL with no detected adverse affects. I was just trying to reach out and see if anyone had comments on bad experiences.

Hi prmmel

Well I didn't know from your first post you already had some experience of the aluminium skids I thought you were just considering it.
I have experience with steel skids for pumps and motors never done one in aluminium though.
