cooling pipe beading
blakep82 - 11/5/10 at 03:58 PM

another one on this from me

got the oyster thing from B&Q, wasn't overly impressed by the height of the bead.

had an idea though... what about 3 or 4 pop rivets equally spaced on the end of each pipe? that would do it wouldn't it?

somebody alrready suggested that but not the way I would do it - due to the rivet ends upsetting the smooth water flow inside the tube.

not seen this?

.... and before someone points out, the flaring also will upset the flow .... but I will try another solution - cut groove in tube outer, wrap some aluminium MIG wire then solder it in place (have some small tubing that my DIY tool is too big to flare.

oh, I should point out that I was able to use my DIY tool with a pair of pliers to put the bead onto a radiator outlet that I shortened so not vice needed.

An oyster soldered onto it has worked fine for me. But yes you could use pop rivets though I wouldn't have though they'd give as much height as an olive!

Yeah, they'll shape quite easily out of their shells, but you might need gaffer tape to hold them on!!! Image deleted by owner

I'll wait to be shot down, but I've never beaded a pipe yet, and I've not had one blow off yet either, even boost pipes running 30psi............

^ yeah, i was thinking about this, they grip on pretty tight anyway... wouldn't like to find out the wrong way though lol

It will be fine as long as its the correct size, silicone hose onto new, clean tubing

the rad hoses on my locost were never beaded and they've not come off in 3 years and 5000 miles

thats what i've got, however, its 35mm tube, and 35mm hose, so are a nice tight fit over the tube, but one of the hoses is slightly slack on the pipe, only like 0.5mm different

that will be fine, just put it all together, and get it really hot stood on the drive, if its going to blow one off it will do it then
