Hydraulic Pipe Repair

[Edhertz]

Has anyone out there done a fracture repair on a hydraulic pipe? The leak is on the pump to accumulator pipe at the accumulator end at the flare junction. I guess this was caused by vibration even though it was well secured by brackets. Is the pipe of two part construction and if it is can it be brazed or silver soldered effectively?
Cheers for replies in advance

Brazed is best....because very high pressure....and it should be sleeved as a "hole fill" would not be that strong I would guess

As Alasdair says exactly, I've made several successful repairs by sleeving and brazing in the past...

Thanks for replies. Problem is the fracture is at the root of the swaged flange so not possible to get a sleeve on it unless it's split.

Me too. The XM hydraulic pipe used to fracture where it enters the pump (usually due to a flat Acc sphere) I silver soldered an appropriately sized olive on the the pipe, only shortened it by about 1/4". Brazing will do, similar temperature - but soft solder won't, Guess how I know.

Thanks for your comments. I might try your method if all else fails. I've got a shout out in the 'wanted section for a pipe ....... worth a try!

Just to finish off this hydraulic pipe saga.

No joy sourcing a replacement apart from a scrapper who wanted £20.00 just for delivery from Swindon. Following Peter.N.'s reply I cut the pipe at the fracture but was unable to obtain a suitable olive, so I made a steel one up on my trusty Harrison L5 with a seating angle of 37 degrees and silver soldered it in the same relative position as original.

Finding this seal in the accumulator inlet was a surprise since it does not appear on the piping parts diagram

Job done!

[Peter.N.]

Well done.

Would you fancy a simple little cash job for your lathe? Make a cone in stainless?

Excellent work

I like clever ways to solve problems ........... well thought out Sir
