 |
|
Just wondering what's the best choice for pipe material for heat dispersal??..
My bus was running silicone from front to back ( rad's up front) but i recently found a set of mgf metal water pipes and was thinking about replacing the middle section on the bus as this might help..am i right in thinking this and would it be even better to get a set of stainless ones off ebay?
or is there something else that would be even better ?

Not much point buying MGF pipes if you are going to cut them up anyway, just buy some tube and make new ones...

It's for a baywindow dude, dont have to cut them up they are fine as they are for the centre section...
Was more interested in the heat dispersal side of things as it's for a scooby turbo...

knowing rover the metal pipes wll only be there to save cash  alloy would be the best for heat dispertion hence why modern car rads are made from it. putting fins on the outside of the pipe like welding 100's of washers to the outside would increase the surface area and help cooiling. check out power steering return hoses alot up the alloy fined idea to get rid of heat

Copper's good for dispersal. Google "Galvanic corrosion" and make your own mind up. Insulate it from steel (piping & chassis)
Plus points: Very easy to bend, cut, solder, commercial fittings available
Minus: Work hardening, corrosion (salt & maybe galvanic)
If you want to get really technical:
Best
Silver
Copper
Gold
Aluminium
Brass
Steel (Relatively, it's really bad)
Ally's used as its value is low in comparison

thats told me then! to be fair as elusive points out copper is more efficent than alloy at heat distibution and you can get fittings as easy as pie for it, but it's expensive in bigger sizes  does anyone know if copper would be ok to be used as main coolant run on a van or could vibration fracture it over time? and would the copper pipes be ok with a alloy head? just thinking out loud but all old cars that ran copper rads mini's escorts etc had all iron engines and now we have alloy heads and all alloy motors we have alloy radiators to match is that just a coincidence or is there more to it like a electrolytic issue etc

I read loads of articles. Copper/steel/ally seem to be ok as long as they don't physically touch each other.
Did see some bloke's write up where he'd used copper. He stripped tje engine 60k. Miles later due to spun bearing. No corrosion.
Make your own decision.
Use a quality coolant.
