I am looking for some advice on repairing oxy/acetylene hoses. A couple of years ago we had some employees trained by BOC on repairing our equipment. I wanted to check to see if we are still ok to repair our own equipment, if it is checked adequately.
We are in heavy industry and therefore use quite a lot of oxy/acetylene hoses as they sustain a fair amount of wear. If any equipment is found to be faulty we use a double ended tailpiece and hose crimps to connect the hoses together. The hoses are then submersed in water to test the equipment. We also carry out daily leak checks on all of our equipment using appropriate leak detector spray and carry out submersible tests weekly.
Do you think we are meeting relevant guidelines and legislation when repairing this equipment or is it now recognised that hoses should be replaced every time there is a leak?
Any help would be greatly appreciated.

Given the possible outcomes from an equipment failure my risk assessment came up with replace, do not repair.
I was not impressed with the amount of time and effort that would be required to PROVE in court
that our repair procedures would have no bearing on any incident involving said equipment .

Worked for BOC safety for 12 years and don't disagree with the procedures you have in place which seem reasonable on face value. Although not my core specialty (It's COMAH) The BCGA CP17 Code of practice does not recommend the repair of Pressure gauges to BS 6752 or BS EN 562 Safety devices to BS 6158 or BS EN 730
Air/fuel gas blowpipes to BS EN 731.
That said however there is a repair and test procedure laid down in the various BS ENs and the outline of this is in the BCGA document CP 17.
Available from BCGA - sorry but you have to pay for that - have a nice day..

Hi,
I also work in heavy industry and we adopt similar methods to you in repairing hoses. we buy approved repair kits from BOC and as long as there is not too many repairs in a length of hose, this is fine (there is a criteria for the amount of repairs in hoses) but am not qiute sure what it is.
Hope this helped

Repair ?
When you take the cost of the time to repair and test into account, and then compare the cost of new hoses (with attached fittings), you are looking at losing money by repairing damaged hoses.
Have you considered looking at the reasons for the damage ?

In most cases the reason hoses get damaged is because the hose itself is worn from being dragged around the workplace, Ozone cracking from age.
Simpler quicker and less bother to replace, cos you will have to anyway. Get the guys to respect the kit,it may just last a little longer.
Anybody smell gas?

Thanks for all of your responses. I additionally wrote to BCGA to ask for their advice. This was their response:
Thanks for the enquiry.
In our Code of Practice CP7 we state that repairs to otherwise good hoses are allowed provided that couplers to BS EN 562 are used and that the completed assembly passes the tests in BS EN 1256.
So in my view your system is in line with our recommendations
Again thank you for your support

Hi Daniel
Just so that you have no remaining illusions:-
In the event of any actual or potential hose failure that could be implicated in any enforcement interest; you cannot rely upon any external guidance in itself.
You will definitely require to be able to prove that you have detailed & specific procedures for repair that include competence to confirm hose either side of repair is not too degraded, explicit procedures that include standards to be attained during the repair, and especially a thorough & robust testing regime to prove the repair is acceptably safe.
