Surface mounted copper

[mfgs]

I have an install job to do in a curved bay where the pipework will all be surface mounted and on show. I am at a loss to know how to bend a full length in a curve to match the bay! Anyone done anything similar?

It has to be spot on and look good. I have 3 radiators to fit around this huge bay.

how much are we talking bend wise?

something like this?

Yeah similar but the full run is about 15m with tee offs for rads. But that's the effect I am after! What do you suggest?

 

[ShaunCorbs]

would need a drawing to see what your on about tbh

So the wall is basically like a semi circle with an circumference of about 25m roughly. I have to run about a 15m run around this huge semi circle with surface mounted pipes. So full 3m lengths need to be bent to match the curve of the wall. If that makes sense?

Imagine running surface pipework around the inside of that building.

Are you having the rads bent to the same curve?

Did this in a pub bay window about 30years ago.
Use a 15mm bending spring, fasten on a piece of earth wire. Mark off measurements on the earth cable and slide it in from each end. Mark of where the spring needs to be and bend with your knee until it’s the same as the bay. Slide the spring out , a bit at a time and repeat the bend until it’s all the same.
Hope this makes some sense.

Its not in the job spec as being curved radiators, so I am assuming thet aren't. But the pipework is stated as being matched to the curve of the wall.

It's only a slow bend then. If you held a three meter length of tube across the bay with the ends touching it, how far away from the wall would the centre of that length be?
Just so I can see it in my minds eye!

At a guess maybe 300-400mm max

 

[ShaunCorbs]

bet you could do that with clips

Would be under a bit of pressure though mate 😱😱😕😕

shouldnt be bad over 15m tho

It is only a slow bend that. I would do it by hand. Take your time.

So how are the bends in the first picture done then?

sand and bent round the cylinder

You can still get 15 soft copper on a coil ?could work with plenty of clips . cheers kop

Why not bring pipes through floor to rads if your trying to make one big rad out of several it may not work unless linking top and bottom and then get cold at last rad ....brum

Could you use tube from a different table?

Sand or water will achieve that kind of bend.
