Testing for Belt Longevity - 20ft Pipe

C

CDAndrews

Hi All,

I have a vendor wanting to run belt sanding tests to prove his belts can significantly decrease cost (over time) by running faster and increase longevity. He has requested to run 5 pieces (20ft in length and about 2" in diameter) repeatedly. These belts (4 in total and 5" wide each) are designed to give a grained appearance to the pipe. The belts will not differ between individual sanders. Each sander will have one belt. Here is my question:

Will running these same 5 pieces repeatedly give me a reliable result as to belt fatigue, load, wear out, etc.?

I would assume, dangerously enough, that once the initial grain has been achieved - on the first pass - that subsequent passes will be easier on the belts than running an unfinished piece each time (as we would in reality). Am I correct?

Thank you all very much!

You need to be able to compare the new to the current baseline. There are two ways to do this: 1) Use the new in the same manner as the current, or 2) Use the current in a parallel study the same as the new.

Yeah, you'd be best served by testing both at the same time, same conditions. Most reliable data achieved that way.

Thank you both very much; I really appreciate your feedback. I was thinking the same. I believe that to be the only way to get a good comparison, without getting into a wrestling match regarding supposed specifics and variables. Unfortunately, while I am the foreman and project manager, I'm not the final decision-maker on the project. I have to ride the line between what I know to be true (and can prove) and how the "more experienced" guys have handled vendors for years. Wish me luck; I'm walking in with my head held high...

I realized the way I replied only showed up in response to normzone's post. I wanted to make sure I thank you directly as well. So, thank you very much for your early and accurate response!
