UUuummmmm...... i give up ! !

Is the "serpentine" a reptile or an animal of some kind ?

Is it a hose ?

Can it move by itself ?

When you go to order a replacement, does the vendor call the serpentine a different name like "hose" or "snake" or coil...?

Always use the name of the object that is used by the supplier or vendor.

No, serpentine is not a reptile, it is a kind of snake. In the cold winter nights, it gets cold and we are trying to isolate all of the serpentine snakes to help them live a happy and healthy life...

If somebody is talking about heat transfer, steel, tank, heat loss, separator, steam etc along with serpentine, it is clear that that serpentine is a heat exchanger.

Try to understand before mocking and learn some manner

aggie,

Go to Online Materials Information Resource - MatWeb. There you will be able to select the appropriate material for your heat transfer system.

I will try.

Thanks.

Stainless steel "serpentine" with more surface. (longer, wider etc) S.M.

Larger bore or wrapped with 1/16" dia. stainless rod spaced 1/16" apart- sort of like fins.

That sounds reasonable. I will think on it.

Thanks.

Dear Aggie,

Open the link below and you will find a very good article about material selection for heat exchangers in desalination plants. I think it will help to solve your problem :

On the other hand, energyguru's solution (stainless steel tube with fins) also sounds like a good idea too.

'...What kind of material would you advise for this situation?...'

Curponickel, is one of numerous alloys you might consider. Cupronickel is often used in sea water heat exchangers because it is resistant to corrosion in sea water and it has good thermal conductivity.

The liquid side heat transfer coefficients are so much smaller than the coefficient in the metal that tghe conductiivity of the metal plays no part in the overall coefficient.

Probably there is heavy fouling on one or both surfaces.
