removing dents from pipes....

[stu]

i remeber a post about this a while back but the search resulted in no threads is there a simple way of removing dents in pipes?? i got an old set of PT mids sat in the garage but there all dented up on the bottom where the pipes bend below the frame rails....silly design if you ask me!!

Theres no point in th pipes being thrown away iof they can be ressurected from the dead!! heres a pic of one of the dents:

ouch those are some killer dents.Plug off one end and either fill it with water,plug off the other end and put it in the freezer, so when the water expands it'll take the dent out, or plug off one end, and put air pressure into the other hole.

It's not really worth trying to do yourself when places like theses do it so cheap.

If you can weld just cut the pipes and bang the dents out with a ballpeen hammer or a rubber mallot. Then just reweld em.

That's what I was thinking but I'd try the water first.

Your best bet. Cut along the old welds and seperate the pipe, do just this and then weld it back.

would the pipes have to be TIG welded back together?? my uncle is a pro MIG welder but has no TIG equipment. Ill try the ice idea when I get back to home

I had a dent in my SST's one time. I took a torch and heated the pipe up to red-hot then put dry ice on the dent and it poped back out after about 10-15 seconds. My dents were about the size of a silver dollar though, not very big.

Take a piece of thick rubber,tire tube etc. and put it over the inlet side of the pipe and secure it with a hose clamp...it is important that it is sealed good.

Put a hose on the exit end of the pipe and clamp it , put an air nozzle into the other end of the hose and clamp that.

The idea is to heat up the dented spots with a torch (rosebud tip) and add air

pressure to the pipe to pop the dents out.(do not exceed 65psi)

It works but it usually discolors the finish on the pipe from the heat so plan

on painting them with hi-temp paint afterwards.

If you heat the pipe cherry red and shoot 150 psi of air into it and the pipe

blows up and kills your poodle, congratulations youre an idiot...and dont

come to me. Dont try this unless you know what you are doing.

 

An easier method is to stick a pertater in the zaust pipe and rev her up to aprox. 600,000 rpm or until the tater is nicely browned... next , pm me as I will buy your

blown up Shee for a fair price

Let us know if it works stu? Otherwise yes it will need tig welded back.

600,000rpm....so about half throttle then, my shee revs to over 1,000,000rpm no wonder that powerband is soooo much fun!!

 

cheers for the help guys, this is a spare set of pipes and there not in a good way! got some DMC's on the shee now, doesnt really matter how they end up so ill try a few things over easter and report back

very interested in the outcome of all this!...pelase let me know or post the results!

thanks in advance

[stu]

i think ill cut them apart with a dremel over easter and then spend a while looking around for a cheap place to get them TIG welded back together. my uncle is a pro MIG welder so he'll be my first point of call....ill get some pics of what im doing in a few weeks for yall

I like that rose bud tip/compresed air idea. Another idea is weld or braise a rod onto the dent then get the area red hot and pull the dent out by pulling on the rod, just don't stab yourself incase the rod breaks. I've done it to headers on a camero before and thats alot thicker metal.
