Looks to me to be the heater pipes.
There seems to be a tiny leak from the component in your picture, I'm unsure of exactly what it is as I've not seen one on any of the vans I've owned but it looks to be either a isolation valve of perhaps a bleed point.

Trust me to be different
The air conditioning doesn't seem to be getting as cold as it used to, could it be something to do with that?

Should have added the air con pipework are the aluminium ones above the ones you refer to.

The white residue is not corrosion but what's left from the coolant after the liquid element of it has evaporated.

With vehicle air con basically it either works or it doesn't, by that I mean if when activated the compressor runs and the pipework gets cold (very cold) it is working. The degree of cold and how quickly it reaches that state will normally be a result of the design and equipment of the system, unlikely to slightly deteriorate over time.

Just been told that in uk, to get your vehicle re gassed has gone through the roof as the government has just put a huge levy on R33 & the like. Which is what most vehicles had before the CFC friendly stuff that is used today came out. They say generally to sw the air con on every now & then to keep the seals in the compressor lubricated. I do not think the picture of jans is refrigerant as it evaporates as soon as it escapes.

Residue after evaporation, not coolant.
