I'm aware of the cost difference with the raw material, but does getting a large frame like that powder coated eat up most of the cost difference?

I am working on a custom, one off, welded frame design for a troughed roller conveyor. This will require a ~8'x2'x3' welded box frame (2" x1/16" thk square tubing) and two u channels about 6" wide, 2" tall, 6' long (9ga) welded on. Customer does not require stainless but painted steel at...

Does anyone know where I can find or how I can design the plastic/rubber seals described in this article? Article is "Key Linear Motion Design Details For Harsh Environments" by linearmotiontips.com Thanks

Hello, I'm looking for some information on different types of finishes or coatings (corrosion resistant) commonly available for aluminum 6061 I commonly use anodizing and electroless nickel. On different machines I've seen aluminum parts with a clear coating that feels smooth like an epoxy.

@25362 That is the same graph that i use. I understand how you could estimate the Pr easily but not the Tr because they are curves.

I understand how to use them but my book gives very exact answers that I feel I could only estimate. Is there a formula used when your P(reduced) and T(reduced) aren't nice numbers to work with? For example a Pr of .977 and a Tr of 1.038. My compressibility chart has a large gap between Tr of 1...
