Steel Central Heating Pipes

[sealo0]

Hi All

Just wondering if someone could answer a quick question?

The central heating in my house is piped in a steel pipe not galvinised(Sp). Before I replace the current boiler next year (I hope) I want to upgrade the bedroom rad's (*2) & bathroom but as the title says these are steel with compression fittings.

Can I just (for now) remove the old steel pipe & pumb in a short lenght of 15mm copper into the existing 15mm steel compression fittings

What sort of steel

Stainless steel was used back in the year dot and would account for the compression fittings.

Don't know off a compression fitting for steel tube which is normally threaded other than leadlok and repair fittings.

Hi

It seems to be extruded but it is within 0.0003/4" of 15 mm copper pipe.

I'd post a picture but i can't see how to do it.

Sounds very much like the old Simplicity Elm Mild Steel Tube that you have installed.

Take it from one who knows - replace the bloody lot, urgently.

It will be going next year.

But what I need to know now is can I insert a copper pipe into these steel compression fittings???

once you mix copper and steel you accelerate corrosion, so be sure to add a corrosion inhibitor.

Hi all

Thanks for all the replies.

JohnD ~ If you have a look at the second I think worring about corrision is a bit late now!!!

The steel compression fitting I'm on about is in img 1 if anyone can say if I can put copper into there, it will hopely only be for 6/8 months

Arghhhh..looks like Tru-wel(d) like I did as an apprentice in 1972 but the job was E.Sussex....those are 3/4 inch pipes and fittings so you`ll need to use adapter olives with 22mm fittings...P.S. I only did the underfloor lagging because I was 1st. year then Never done anything like the other pic.

You will be ok using copper,your fittings are brass.The pipe could be a sort of stainless steel,used during a copper shortage in the late 70s,ive come across it a few times,bit of a bastard to cut and bend,try and replace it when possible.
