Even if you do need to make thicker pipes, strength in a metal generally increases with the square of the thickness, so it doesn't cost twice as much in materials to double the strength.
- londons_explore 4y agoThis isn't true. For pipes, double the pressure requires double the wall thickness, which requires double the material. However, I don't think raw material cost is a big part of the cost of refrigeration systems anyway.
- samtho 4y agoThe “soft” copper tubing they use in refrigerant lines is not only very cheap (it’s not 100% copper) but is very much over built for pressure it is likely going to be subject to. It’s way cheaper, in this instance, to simply sell a line set that works with 99% of systems instead of having dedicated factory lines and consumer confusion from having different grades of registrant tubing.
